Trang 31 Introduction
Equities represent a significant portion of the portfolio for many investors Hence, equity portfolio
management decisions are very important This reading brings together a lot of knowledge learnt at
Level I and Level II and applies it in a practical manner
2 The Role of the Equity Portfolio
This section addresses LO.a
LO.a: Discuss the role of equities in the overall portfolio
Equity as an asset class represents a significant source of wealth in the world today US equity markets
amount to about half of the world’s equity markets
Equity can be found in both individual and institutional portfolios For example, pension funds typically
allocate on average about 47% to equities
Investing internationally across multiple markets offers diversification benefits
It has been observed that as compared to bonds, equities offer superior protection against
unanticipated inflation This is because companies are able to pass on some of the inflation to customers
and their earnings tend to rise with inflation
Historical data suggests that equities have long term rates of return They therefore play an important
role in the portfolio
3 Approaches to Equity Investing
This section addresses LO.b
LO.b: Discuss the rationales for passive, active, and semi-active (enhanced index) equity investment
approaches and distinguish among those approaches with respect to expected active return and
tracking risk
Passive Management
In passive management, investors do not change their security holdings even if their outlook changes
They assume that in general the equity market is efficient, hence indexing is the best strategy They
simply invest in a portfolio that attempts to match the performance of a benchmark index However, it
is important to note that this approach is not completely passive because the portfolio needs to change
when the index is reconstituted or when the weight of a stock in the index changes
Active Management
Active managers try to outperform the benchmark portfolio by investing in underpriced securities and
avoiding (or shorting) overpriced securities Although passive management is gaining popularity, active
management continues to be the dominant management style
Semiactive Management
Trang 4This approach is also called enhanced indexing or risk-controlled active management It is a variant of
active management Here the manager tries to outperform benchmark but at the same time also tries to
keep tracking risk in control
Comparison
Refer to Exhibit 3, which shows a comparison of the three approaches Typically the enhanced indexing
approach tends to have the highest information ratio
Indexing Enhanced Indexing Active
Expected active return (excess return over
Tracking risk (standard deviation of active
LO.c: Recommend an equity investment approach when given an investor’s investment policy
statement and beliefs concerning market efficiency
While several variables need to be considered in making a decision about the appropriate investment
approach, the most important factor is the investor’s view on market efficiency If the investor
believes that markets are efficient, then a passive management strategy should be employed On the
other hand if the investor believes that there are inefficiencies in the market which can be exploited
then an active management strategy is preferable
4 Passive Equity Investing
According to William Sharpe:
before accounting for transaction costs, the return on the average actively managed dollar will
equal the return on the average passively managed dollar; and
after accounting for transaction costs, the return on the average actively managed dollar will be
less than the return on the average passively managed dollar
Therefore it makes sense to purse passive equity investing strategies
4.1 Equity Indexes
A stock index’s characteristics are determined by four choices:
1 Boundaries of stock index’s universe: Broader universe will measure overall market
performance Narrower universe will measure performance of only a specific group of stocks
2 Criteria for inclusion: Defines the requirements that a company must satisfy to be included in
Trang 5(includes dividends)
LO.d: Distinguish among the predominant weighting schemes used in the construction of major
equity market indexes and evaluate the biases of each
Price weighted:
Here each stock is weighted according to absolute share price
The index is biased towards the highest price share
The performance of the index represents the performance of a portfolio that simply bought and
held one share of each index component
It is simple to construct The index is the sum of the share prices divided by the number of
shares
The DJIA is the most prominent example of a price weighted index
Value weighted:
Here each stock is weighted according to its market cap
A sub category is float-weighted index, where the market cap is adjusted to reflect the number
of shares that are actually available to investors For example, if a large portion of shares is held
by promoters and is not available for trading then, it will be excluded in the free float market
Here all stocks are weighted equally
The index has a small company bias, because it includes many more small companies
It requires frequent rebalancing because varying stock returns will cause stock weights to drift
from the calculated equal weights
Refer to Example 1 from the curriculum
4.2 Passive Investment Vehicles
This section addresses LO.e
LO.e: Compare alternative methods for establishing passive exposure to an equity market, including
indexed separate or pooled accounts, index mutual funds, exchange-traded funds, equity index
futures, and equity total return swaps
The main choices available for passive investment vehicles are:
1 Indexed portfolios
2 Equity index futures
3 Equity total return swaps
Trang 6Indexed Portfolio
The main categories of indexed portfolios are:
conventional index mutual funds
exchange-traded funds (ETFs)
separate accounts or pooled accounts
The following table shows a comparison between a conventional index mutual fund and an exchange
traded fund
Conventional (Open End) Index Mutual
Funds
Buy/sell shares at market close at NAV Buy/sell any time during trading day ETF
Shareholder accounting at the fund level
can be a significant expense
No fund level shareholder accounting ETF
Less tax efficient (because selling shares
results in higher capital gains taxes)
More tax efficient (because in-kind redemption process results in fewer taxable events)
ETF
Cost associated with providing liquidity to
shareholders who are selling fund shares
Transaction costs for those buying/selling ETF but those holding shares have protection
ETF
Separate accounts or pooled accounts
Generally, indexed institutional portfolios are managed as separate or pooled accounts (having multiple
portfolios under the same management) When a portfolio is large – as is the case with institutional
portfolios – the use of separate or pooled accounts is more cost effective compared to both
conventional index mutual funds and exchange traded funds
Equity index futures
These are low cost vehicles for obtaining equity market exposure
However they have finite lives, and must be rolled over to maintain a long term position
In a portfolio trade, a basket of stocks are traded together
However, a basket cannot be shorted if any of the components violate the uptick rule This
makes trading cumbersome
Because of these reasons ETFs are more popular compared to index futures
Equity total return swaps
They are a relatively low cost way of obtaining long term exposure to an equity market
They major applications are:
o Receive total return of a non-domestic equity index in return for an interest payment to
a counterparty that holds underlying equities more tax efficiently
Trang 7o Use equity swaps to rebalance portfolios because trading securities might be more
costly
Approaches to creating a indexed portfolio
This section addresses LO.f
LO.f: Compare full replication, stratified sampling, and optimization as approaches to constructing
an indexed portfolio and recommend an approach when given a description of the investment
vehicle and the index to be tracked
Full replication
All stocks in the index are included in the portfolio
The advantages are that the tracking risk is low and the portfolio only needs to be rebalanced
when the index constituents change
The portfolio return is lower than index return due to:
o Administrative fees
o Transaction costs
o Cash drag
Stratified sampling
Allows manager to build a portfolio that retains the basic characteristics of the index without
having to buy all stocks in the index
Process
o A matrix is created using two or more dimensions
o The index stocks are placed in different cells of the matrix according to their
characteristics
o The weights of each cell is calculated
o Random sample are drawn from each cell and the samples are included in the index
based on the calculated weights
Compared to full replication it has lower costs but higher tracking error
Optimization
It is a mathematical approach to index fund creation involving the use of:
o a multifactor risk model, against which the risk exposures of the index and individual
securities are measured, and
o an objective function that specifies that securities be held in proportions that minimize
expected tracking risk relative to the index subject to appropriate constraints
It has lower tracking risk than stratified sampling
The drawbacks are:
o Even the best models can be imperfectly specified
o There can be false signals due to overfitting of data
o Even in the absence of index changes and dividend flows, optimization requires periodic
trading to keep the risk characteristics of the portfolio aligned with the risk
Trang 8characteristics of the index being tracked

5 Active Equity Investing
5.1 Equity Styles
Refer to Example 3 from the curriculum
This section addresses LO.g and LO.h
LO.g: Explain and justify the use of equity investment–style classifications and discuss the difficulties
in applying style definitions consistently
LO.h: Explain the rationales and primary concerns of value investors and growth investors and
discuss the key risks of each investment style
5.1.1 Value investment style
Here the focus is to buy stocks that are relatively cheap in terms of purchase price of earnings or
assets
The belief is that most investors over-pay for glamor (growth) stocks So it is best to avoid them
and look for value in the not-so-glamorous stocks
Empirical studies show that value style may earn positive return premium relative to market
The main risk of this strategy is that a stock’s cheapness can be misinterpreted A stock may be
cheap because of a good reason, and a value investor may fail to factor this reason
The main sub styles are:
o Low price multiple
o High dividend yield
o Contrarian: Look for stocks which are in trouble and selling at low P/B
5.1.2 Growth Investment style
Here the focus is to buy stocks which have high earnings growth
The belief is that if earnings go up and P/E stays the same, then stock prices will go up
Growth stocks have high sales growth relative to the market and tend to trade at high P/Es, P/Bs
and P/Ss ratios
If a stock is trading at a premium, growth investors expects this premium to remain
The main risk for a growth investor is that the expected growth does not materialize
The main sub styles are:
o Consistent growth: Historical record of growth that is expected to continue in future
o Earnings momentum: Hold the stock as long as the momentum in earnings continues
and sell when the momentum breaks
5.1.3 Other active management styles
Market oriented style
Trang 9 This style falls between value and growth An investor will buy a stock if the market value is less
than intrinsic value
The sub styles are:
o Market-oriented with value-bias
o Market-oriented with growth-bias
o Growth-at-a-reasonable price
o Style rotators: Adopt a style that is expected to work in the near future
Market capitalization based style
Small cap investors believe that smaller firms tend to be underpriced as compared to intensely
researched large cap stocks
Mid cap investors believe that mid-caps are less researched than large caps and are less risky
than small caps
Large cap investors favor the relative stability of large companies
Refer to Example 4 from the curriculum
5.1.4 Techniques for identifying Investment Styles
This section addresses LO.i
LO.i: Compare techniques for identifying investment styles and characterize the style of an investor
when given a description of the investor’s security selection method, details on the investor’s
security holdings, or the results of a returns-based style analysis
Two major approaches are:
Returns-Based Style Analysis (RBSA)
Focus on characteristics of overall portfolio as revealed by portfolio’s realized returns
Regress the portfolio returns against the return series of a set of security indexes
The indexes should be 1) mutually exclusive, 2) exhaustive with respect to manager’s
investment universe, and 3) should have distinct sources of risk (ideally should not be highly
correlated)
The regression coefficients or betas should be non-negative and sum to 1
For example, Rp = 0.75 x LCVI + 0 x LCGI + 0.25 x SCVI + 0 x SCGI
Here the portfolio had a beta of 0.75 on a large-cap value index (LCVI), a beta of 0 on a large-cap
growth index (LCGI), a beta of 0.25 on a small-stock value index (SCVI), and a beta of 0 on a
small-stock growth index (SCGI) We could infer that the portfolio was run as a value portfolio
with some exposure to small stocks
Refer to Example 5 from the curriculum
Refer to Example 6 from the curriculum
Refer to Example 7 from the curriculum
Holdings-Based Style Analysis
Trang 10 Here we categorize individual securities by their characteristics and aggregate results to reach a
conclusion about the overall style of the portfolio
An analyst may examine the following variables:
o Valuation levels: A value oriented portfolio will have companies with low P/E, P/B ratios
o Forecast EPS growth rate: A growth oriented portfolio will have companies with high
forecasted EPS growth rate
o Earnings variability: A value-oriented portfolio will hold companies with greater earnings
variability because of the willingness to hold companies with cyclical earnings
o Industry sector weighting: Growth oriented portfolios tend to have higher weights for
industries such as IT and healthcare Value oriented portfolios tend to have higher weights for industries such as finance and utilities
Refer to Example 8 from the curriculum
Refer to Exhibit 15 which summarizes the advantages and disadvantages of the two approaches
Exhibit 15 Two Approaches to Style Analysis: Advantages and Disadvantages
Returns-based
style analysis
Characterizes entire portfolio
Facilitates comparisons of portfolios
Aggregates the effect of the investment process
Different models usually give broadly similar results and portfolio characterizations
Clear theoretical basis for portfolio categorization
Requires minimal information
Can be executed quickly
Holdings-based style
analysis
Characterizes each position
Facilitates comparisons of individual positions
In looking at present, may capture changes in style more quickly than returns-based analysis
Does not reflect the way many portfolio managers approach security selection
Requires specification of classification attributes for style; different
specifications may give different results
More data intensive than based analysis
returns-5.1.5 Equity Style Indexes
This section addresses LO.j
LO.j: Compare the methodologies used to construct equity style indexes
Trang 11A security may be assigned:
to value exclusively or to growth exclusively in all instances;
to value exclusively or to growth exclusively but only if the value of some characteristic exceeds
or is less than a specified threshold value; or
in part to growth and in part to value
There is no clear definition available to distinguish between value and growth However, the trend is
towards using multiple variables – price, earnings, book value, dividends, growth rates, etc – in deciding
how to categorize a stock
Buffering refers to rules for maintaining the previous style assignment when the stock has not clearly
moved to a new style It reduces turnover in style classification and therefore reduces transaction
expenses
Refer to Example 9 from the curriculum
The following sections addresses LO.k
LO.k: Interpret the results of an equity style box analysis and discuss the consequences of style drift
5.1.6 The Style Box
The style box is a popular method of characterising a portfolio’s style The most widely recognized
version of the style box is the Morningstar style box
Refer to Exhibit 18 which shows the Morningstar style box for Vanguard Mid-cap growth fund As shown
most of the fund’s holdings are midcap growth stocks
Value Blend Growth
5.1.7 Style Drift
Style drift occurs when a portfolio manager deviates from his original stated style objective Professional
investors view inconsistency in style, or style drift, as an obstacle to investment planning and risk control
because:
Investor does not get the desired exposure to a particular style
The manager may be operating in an area outside his expertise
Refer to Example 10 from the curriculum
5.2 Socially Responsible Investing
This section addresses LO.l
LO.l: Distinguish between positive and negative screens involving socially responsible investing
criteria and discuss their potential effects on a portfolio’s style characteristics
Trang 12Socially responsible investing (SRI), also called ethical investing, integrates ethical values and societal
concerns with investment decisions SRI criteria may include:
industry classification, reflecting concern for sources of revenue judged to be ethically
questionable (tobacco, gaming, alcohol, and armaments are common focuses); and
corporate practices (for example, practices relating to environmental pollution, human rights,
labor standards, animal welfare, and integrity in corporate governance)
The screens may be negative, for example where an investor refuses to invest in an alcohol, tobacco or
armaments company Or the screens may be positive, for example where an investor only wishes to
invest in companies that have good corporate practices
Analyst should understand the impact of an SRI criteria on portfolio’s financial characteristics If you
know the potential biases introduced by SRI, you can take appropriate actions determine the
appropriate benchmark
5.3 Long–Short Investing
This section addresses LO.m
LO.m: Compare long–short and long-only investment strategies, including their risks and potential
alphas, and explain why greater pricing inefficiency may exist on the short side of the market
This style focuses on exploiting the constraint that many investors face related to short sales The belief
is that since many investors cannot take short positions, stocks may become overvalued
Pair’s Trade
Here an investor goes long an undervalued stock and goes short an overvalued stock from the
same industry
The major risk comes from the use of excessive leverage, which can magnify losses
Price Inefficiency on the Short Side
The reasons for price inefficiencies can be:
Many investors only look for undervalued stocks
Management fraud, window dressing, negligence
Bias towards ‘buy’ recommendations
Sell-side analysts may be reluctant to issue negative opinions
Equitizing a Market-Neutral Long–Short Portfolio
LO.n: Explain how a market-neutral portfolio can be “equitized” to gain equity market exposure and
compare equitized market-neutral and short-extension portfolios
A market-neutral long–short portfolio has no market exposure In other words the market beta is 0
Such a portfolio can be equitized (given equity market exposure) by taking a long position in equity
futures contracts This is an appropriate strategy when an investor wants to add an equity beta to the
return It is important to note that, in some markets ETF’s may be a more attractive way than futures to
equitize This is because futures contracts are short-term and need to be rolled over frequently This can
Trang 13be costly
The Long-Only Constraint
The long-only constraint limits an investor’s ability to benefit from an extreme negative view on a stock
The most that the investor can do is reduce his weightage to 0 Thus, long-short strategies have an
advantage over long-only portfolios
Short Extension Strategies
Such strategies partially relax the long-only constraint by specifying the level of short selling allowed For
example 130/30 means an investor can short 30% of the portfolio value and use the proceeds to go long
on 130% of the portfolio value Refer to the table below for a comparison between an equitized
long-short strategy and a long-short extension strategy
Equitized long-short strategy Short extension strategy
Needs a liquid futures, swaps or ETF
market
Does not need a liquid futures, swaps or ETF market
It has zero beta and hence is
considered an alternative investment
It is a substitute to a long-only strategy and not considered an alternative investment
Appreciable increase in the proportion of a manger’s investment insight that is incorporated in the portfolio
Gain market return and earn alpha from the same source
Refer to Example 11 from the curriculum
5.4 Sell Disciplines/Trading
This section addresses LO.o
LO.o: Compare the sell disciplines of active investors
An investor may need to sell stocks to rebalance or to raise cash The use of various strategies can help
the investor decide when to sell
Substitution: replace existing holding when another stock offers higher risk-adjusted return
Rule based: Sell when a certain rule or criteria is met For example a value investor might sell if the P/E
ratio rises above a certain level
Implications of sell discipline need to be evaluated on an after-tax basis Value investors generally have
relatively low turnover; they buy cheap stocks hoping to reap relatively long term reward
6 Semi-Active Equity Investing
This section addresses LO.p
LO.p: Contrast derivatives-based and stock-based enhanced indexing strategies and justify
enhanced indexing on the basis of risk control and the information ratio
Trang 14This is a variant of active management and is also called ‘enhanced index’ or ‘risk controlled active’ In
this approach the manager tries to outperform the benchmark but also keeps tracking risk in control As
shown earlier in Exhibit 3, enhanced indexing strategies tend to have the highest information ratio
Semiactive equity strategies come in two forms:
Derivatives based
Here the manager obtains exposure to the desired equity market through a derivative
The enhanced return is obtained through something other than equity
For example, if a manager is equitizing cash i.e holding cash and an long position in an equity
futures contract, then he can enhance his returns by altering the duration of the underlying
cash If the yield curve is upward sloping, he would invest in 3 year notes instead of 90 day bills
to get additional returns
Stock based
Here the manager tries to generate alpha by identifying stocks that are underpriced or
overpriced
If manager has no opinion on a stock then it will be kept at benchmark weight
Risk is controlled by limiting the degree to which a stock can be underweighted or
overweighted
Fundamental law of active management
The fundamental law of active management states that an investor’s investment ratio (IR) is equal to
what he knows about a given investment (the information coefficient, IC) multiplied by the square root
of the number of investment decisions made each year (Breadth)
IR = IC√Breadth
The IC is measured by comparing the investor’s forecast against the actual outcomes Skillful managers
have higher IC The narrower an investor’s breadth, the greater the IC must be to produce a good
information ratio
Refer to Example 12 from the curriculum
Refer to Example 13 from the curriculum
7 Managing a Portfolio of Managers
This section addresses LO.q
LO.q: Recommend and justify, in a risk-return framework, the optimal portfolio allocations to a
group of investment managers
To allocate funds to equity an investor needs to choose between passive management and active
management As we move from passive management to active management, the expected active return
and active risk increases The combination of equity mangers that will maximize the active returns for a
given level of active risk (determined by the investor’s level of aversion to active risk) is obtained by the
Trang 15following objective function
Maximize (by choice of managers) UA = rA− λ𝐴σA2
where,
UA = expected utility of the active return of the manager mix
rA= expected active return of the manager mix
λ𝐴 = the investor’s trade-off between active risk and active return; measures risk aversion in active risk
terms
σ𝐴2 = variance of the active return
Consider a hypothetical case where the performance of available managers is shown in Exhibit 21
Expected Active Return Expected Tracking Risk
Using the values in the above table, we can generate the following efficient frontier (Exhibit 22)
We can also generate the following waterfall chart (Exhibit 23) that shows the manager mix for each
level of active risk
Trang 16Now, given a level of active risk, we can choose a manager mix that will maximize active returns For
example, for an active risk of 1.51%, the manger allocation is shown below (Exhibit 24)
Based on the efficient frontier graph in Exhibit 22, an active risk of 1.51 corresponds to an active return
of 1.92% This means the information ratio (IR) = 1.92 / 1.51 = 1.27
The portfolio active return and risk can also be calculated using the following formulae:
Portfolio active return = ∑ hAirAi
n
i=1Where,
ℎ𝐴𝑖= weight assigned to the ith manager
𝑟𝐴𝑖= active return of the ith manager
Portfolio active risk = √∑ hAi2 σAi2
n
i=1
Trang 17Where,
h Ai = the weight assigned to the ith manager
σAi = the active risk of the ith manager
This following sections addresses LO.r
LO.r: Explain the core-satellite approach to portfolio construction and discuss the advantages and
disadvantages of adding a completeness fund to control overall risk exposures
7.1 Core-Satellite
In a core-satellite approach, majority of the funds are allocated to index or semi-active mangers (core)
and the remaining funds are allocated to a ring of active managers around the core (satellites)
The allocation shown earlier (Exhibit 24) is an example of core satellite allocation
The core minimizes active risk, whereas the satellites add active returns using smaller portions of the
portfolio
Refer to Example 14 from the curriculum
LO.s: Distinguish among the components of total active return (“true” active return and “misfit”
active return) and their associated risk measures and explain their relevance for evaluating a
portfolio of managers
To evaluate managers, we need to divide their total active returns into two components
1 Manager’s return − Manager’s normal benchmark = Manager’s “true” active return
2 Manager’s normal benchmark − Investor’s benchmark = Manager’s “misfit” active return
The manger’s total active risk can be calculated as:
Manager’s total active risk = [(Manager’s “true” active risk)2
+ (Manager’s “misfit” active risk)2]½
This distinction between ‘true’ active risk and ‘misfit’ active risk is useful for:
Performance appraisal of the managers
Optimizing a portfolio of managers
7.2 Completeness Fund
A completeness fund is similar to core-satellite approach However, here we first start with a group of
active managers We then add a completeness fund This is done by identifying a basket or a number of
trades which complete the fund, i.e minimize the active risk of the portfolio
7.3 Other Approaches: Alpha and Beta Separation
This section addresses LO.t
LO.t: Explain alpha and beta separation as an approach to active management and demonstrate the
use of portable alpha
Trang 18In this approach beta exposure is obtained thorough an inexpensive index fund manager To get alpha
exposure, the investor can explicitly hire a market neutral long-short manager
The advantage of this approach is that alpha and beta returns can be generated from different markets
For example, the investor might want to get beta returns on a relatively efficient part of the equity
market (e.g Russel Top 200) and the alpha returns can be generated from asset classes even outside the
beta asset class (e.g a long-short portfolio of Japanese equity) This is also called portable alpha
8 Identifying Selecting and Contracting with Equity Portfolio Mangers
This section addresses LO.u
LO.u: Describe the process of identifying, selecting, and contracting with equity managers
The following sections address some of the issues that investors will face in identifying, selecting, and
contracting with equity managers
8.1 Developing a Universe of Suitable Manager Candidates
Typically investment consultants are used to identify suitable managers They start with a general
evaluation of a large number of managers Managers that seem good are then researched and
monitored further
Consultants use both qualitative and quantitative factors in evaluating investment managers Qualitative
factors include the people and organizational structure, the firm’s investment philosophy, the
decision-making process, and the strength of its equity research Quantitative factors include performance
comparisons with benchmarks and peer groups
8.2 The Predictive Power of Past Performance
Past performance is no guarantee of future results Managers who were top performers in the past, may
not be top performers in future However, past performance can still be useful For example, an active
manager who has consistently failed to beat his benchmark is unlikely to be considered a good active
manager
8.3 Fee Structures
Ad Valorem Fees
Ad valorem fees are calculated as a percentage of assets under management They are also called AUM
fees Example: 0.60 percent on the first £50 million, and 0.45 percent on assets above £50 million The
advantage of ad valorem fees are that they are simple and predictable The disadvantage is that they do
not align the interests of the manger and the investor
Performance Based Fees
This is typically a combination of a base fee plus a sharing percentage For example, 0.2% of AUM plus
20% of performance in excess of benchmark They can also include features like:
Fee cap – Limits the total fees paid
Trang 19 High watermark – Fees will be paid only if performance exceeds previous highest performance
The advantage is that they align the interests of investors and managers
The disadvantage of performance based fees are:
They are complicated and require precise definition
They are like a call option to a manger and encourage taking unnecessary risk
8.4 The Equity Manager Questionnaire
A questionnaire can be used to compare different potential mangers If the response to the
questionnaire is good, then the manager can be evaluated further A typical equity manager
questionnaire examines five key areas:
Refer to Example 15 from the curriculum
Refer to Example 16 from the curriculum
9 Structuring Equity Research and Security Selection
Top-Down versus Bottom-Up Approaches
This section addresses LO.v
LO.v: Contrast the top-down and bottom-up approaches to equity research
Top-down approach
In a top-down approach we start with country analysis then move down to industry and then to specific
securities
In top-down analysis an investor may hope to find:
1 themes affecting the global economy;
2 the effect of those themes on various economic sectors and industries;
3 any special country or currency considerations; and
4 individual stocks within the industries or economic sectors that are likely to benefit most from
the global themes
Bottom-up approach
In a bottom-up approach we start at the individual stock level, the focus is on security selection
The usual steps followed are:
1 identifying factors with which to screen the investment universe (e.g., stocks in the lowest P/E
quartile that also have expected above-median earnings growth);
Trang 202 collecting further financial information on companies passing the screen; and
3 identifying companies from this subset that may be potential investments based on other
company-specific criteria
Refer to Example 17 from the curriculum
Buy-Side versus Sell-Side Research
Buy-Side
This is research with the intent of assembling a portfolio They may also use sell-side research
The buy/sell decisions are generally made by a committee
This research is generally inaccessible to outsiders
Sell-side
This is research conducted by independent researchers who sell their work or investment
banks/brokerage firms which use research as a means to generate business
Sell-side research is easily available to the general public
Industry Classification
Equity research is usually conducted as per industry/sector Hence it is important to have a system that
classifies similar companies into similar categories
The Global Industry Classification Standard (GICS) developed by Standard and Poor’s and MCSI divides
stocks into:
10 Sectors (Consumer Discretionary, Consumer Staples, Energy, Financials, Health Care,
Industrials, Information Technology, Materials, Telecommunication, and Utilities);
24 Industry Groups;
68 Industries;
154 Sub-Industries
Summary
a discuss the role of equities in the overall portfolio;
Equity represents a significant source of wealth
Equity can be found in both individual and institutional portfolios
Equities offer superior protection against unanticipated inflation
Equities have provided high returns over the long term relative to other asset classes
b discuss the rationales for passive, active, and semi-active (enhanced index) equity investment
approaches and distinguish among those approaches with respect to expected active return and
Trang 21involves investing in underpriced securities to beat the market
3) Semi-active or enhanced indexing assumes that markets offer opportunities to achieve a positive
information ratio with limited risk relative to a benchmark It has two objectives, i) to outperform
benchmark and ii) to keep tracking risk in control
Indexing Enhanced Indexing Active
Expected active return (excess return over
benchmark)
Tracking risk (standard deviation of active returns) < 1% 1% – 2% 4%+
c recommend an equity investment approach when given an investor’s investment policy statement
and beliefs concerning market efficiency;
The most important factor in determining the appropriate investment approach is the investor’s view on
market efficiency
If the investor believes that markets are efficient, then a passive management strategy should be
employed
On the other hand, if the investor believes that there are inefficiencies in the market which can be
exploited then an active management strategy is preferable
d distinguish among the predominant weighting schemes used in the construction of major equity
market indexes and evaluate the biases of each;
Price weighted:
Each stock is weighted according to absolute share price
The index is biased towards the highest price share
The performance of the index represents the performance of a portfolio that simply bought and
held one share of each index component
It is simple to construct The index is the sum of the share prices divided by the number of
shares
The DJIA is the most prominent example of a price weighted index
Value weighted:
Each stock is weighted according to its market cap; sub category is float-weighted index
The index is biased towards large companies that have high market-cap and towards overvalued
stocks
Equal weighted:
All stocks are weighted equally
The index has a small company bias, because it includes many more small companies
It requires frequent rebalancing because varying stock returns will cause stock weights to drift
from the calculated equal weights
Trang 22e compare alternative methods for establishing passive exposure to an equity market, including indexed
separate or pooled accounts, index mutual funds, exchange-traded funds, equity index futures, and
equity total return swaps;
The main choices available for passive investment vehicles are:
1 Indexed portfolios
2 Equity index futures
3 Equity total return swaps
Indexed Portfolios
The main categories of indexed portfolios are:
conventional index mutual funds
exchange-traded funds (ETFs)
separate accounts or pooled accounts: When a portfolio is large, the use of separate or pooled
accounts is more cost effective compared to both conventional index mutual funds and exchange
traded funds
Conventional (Open End) Index Mutual Funds Exchange Traded Funds
Buy/sell shares at market close at NAV Buy/sell any time during trading day
Shareholder accounting at the fund level can be a
significant expense
No fund level shareholder accounting
Less tax efficient (because selling shares results in
higher capital gains taxes)
More tax efficient (because in-kind redemption process results in fewer taxable events)
Cost associated with providing liquidity to
shareholders who are selling fund shares
Transaction costs for those buying/selling ETF but those holding shares have protection
Equity index futures
These are low cost vehicles for obtaining equity market exposure
They have finite lives, and must be rolled over to maintain a long term position
In a portfolio trade, a basket of stocks is traded together
A basket cannot be shorted if any of the components violate the uptick rule This makes trading
cumbersome
Because of these reasons ETFs are more popular compared to index futures
Equity total return swaps
They are a relatively low cost way of obtaining long term exposure to an equity market
The major applications are:
o Receive total return of a non-domestic equity index in return for an interest payment to a
counterparty that holds underlying equities more tax efficiently
o Use equity swaps to rebalance portfolios because trading securities might be costlier
Trang 23f compare full replication, stratified sampling, and optimization as approaches to constructing an
indexed portfolio and recommend an approach when given a description of the investment vehicle and
the index to be tracked;
Full replication: all stocks in the index are included in the portfolio
Tracking risk is low and the portfolio only needs to be rebalanced when the index constituents
change
The portfolio return is lower than index return due to: administrative fee, transaction costs, cash
drag
Stratified sampling: retain basic characteristics of the index without having to buy all stocks in the index
Compared to full replication it has lower transaction costs but higher tracking error
Optimization: mathematical approach to index fund creation involving the use of a multifactor risk
model
Process
Risk exposures of the index and individual securities are measured
An objective function that specifies that securities and weights that minimize expected tracking
risk
Advantage:
o Lower tracking risk than stratified sampling
Drawbacks:
o Even the best models can be imperfectly specified
o There can be false signals due to overfitting of data
o Even in the absence of index changes and dividend flows, optimization requires periodic trading
to keep the risk characteristics of the portfolio aligned with the risk characteristics of the index
being tracked
g explain and justify the use of equity investment–style classifications and discuss the difficulties in
applying style definitions consistently;
h explain the rationales and primary concerns of value investors and growth investors and discuss the
key risks of each investment style;
Value investment style: buy stocks that are relatively cheap in terms of purchase price of earnings or
assets i.e stocks with low P/E or P/B ratios
The belief is that most investors over-pay for glamor (growth) stocks So it is best to avoid them and
look for value in the not-so-glamorous stocks
Empirical studies show that value style may earn positive return premium relative to market
The main risk of this strategy is that a stock’s cheapness can be misinterpreted A stock may be
cheap because of a good reason, and a value investor may fail to factor this reason
The main sub styles are: low price multiple, high dividend yield, contrarian (low price to book)
Growth investment style: buy stocks which have high earnings growth
The belief is that if earnings go up and P/E stays the same, then stock prices will go up
Growth stocks have high sales growth relative to the market and tend to trade at high P/Es, P/Bs
and P/Ss ratios
Trang 24 If a stock is trading at a premium, growth investors expects this premium to remain
The main risk for a growth investor is that the expected growth does not materialize
The main sub styles are: consistent growth, earnings momentum
Market oriented style falls between value and growth; buy if the market value is less than intrinsic
value
Market capitalization based style: favor stocks based on market capitalization
i compare techniques for identifying investment styles and characterize the style of an investor when
given a description of the investor’s security selection method, details on the investor’s security
holdings, or the results of a returns-based style analysis;
Techniques for identify investment styles:
Returns-Based Style Analysis (RBSA)
Focus on characteristics of overall portfolio as revealed by portfolio’s realized returns
Regress the portfolio returns against the return series of a set of security indexes
The indexes should be 1) mutually exclusive, 2) exhaustive with respect to manager’s investment
universe, and 3) should have distinct sources of risk
The regression coefficients or betas should be non-negative and sum to 1
Holdings-Based Style Analysis
Here we categorize individual securities by their characteristics and aggregate results to reach a
conclusion about the overall style of the portfolio
An analyst may examine the following variables:
Valuation levels: A value oriented portfolio will have companies with low P/E, P/B ratios
Forecast EPS growth rate: A growth oriented portfolio will have companies with high forecasted
EPS growth rate
Earnings variability: A value-oriented portfolio will hold companies with greater earnings
variability because of the willingness to hold companies with cyclical earnings
Industry sector weighting: Growth oriented portfolios tend to have higher weights for industries
such as IT and healthcare Value oriented portfolios tend to have higher weights for industries
such as finance and utilities
Returns-based style
analysis
Characterizes entire portfolio
Facilitates comparisons of portfolios
Aggregates the effect of the investment process
Different models usually give broadly similar results
and portfolio characterizations
Clear theoretical basis for portfolio categorization
Requires minimal information
Can be executed quickly; cost effective
May be ineffective in
characterizing current style
Error in specifying indexes
in the model may lead to inaccurate conclusions
Trang 25Holdings-based style
analysis
Characterizes each position
Facilitates comparisons of individual positions
In looking at present, may capture changes in style
more quickly than returns-based analysis
Does not reflect the way many portfolio managers approach security selection
Requires specification of classification attributes for style; different
specifications may give different results
More data intensive than
returns-based analysis
j compare the methodologies used to construct equity style indexes;
Methodologies to construct indexes:
A security may be assigned:
to value exclusively or to growth exclusively in all instances
to value exclusively or to growth exclusively but only if the value of some characteristic exceeds
or is less than a specified threshold value
in part to growth and in part to value
k interpret the results of an equity style box analysis and discuss the consequences of style drift;
The style box is a popular method of characterising a portfolio’s style The most widely recognized
version of the style box is the Morningstar style box
Morningstar Style Box for Vanguard Mid-Cap Growth Fund
Style drift occurs when a portfolio manager deviates from his original stated style objective Professional
investors view inconsistency in style, or style drift, as an obstacle to investment planning and risk control
because:
Investor does not get the desired exposure to a particular style
The manager may be operating in an area outside his expertise
l distinguish between positive and negative screens involving socially responsible investing criteria and
discuss their potential effects on a portfolio’s style characteristics;
Socially responsible investing (SRI), also called ethical investing, integrates ethical values and social
concerns with investment decisions
