Trang 11 INTRODUCTION
Decision of how to invest in competing equity investments ranks second to how much to allocate to equities
SD = Standard Deviation
ER = Equity Research
MF = Mutual Fund
2 THE ROLE OF THE EQUITY PORTFOLIO
economic factors & no exact home-market equivalent
tax real return, price competition may limit price due to inflation)
Both domestic & international equities play an important role in individual/institutional portfolios
3 APPROACHES TO EQUITY INVESTMENT
Passive Management Active Management Semi Active
expectations in security selection
indexing
implementation
Seeks to outperform benchmark through security selection
More concerned about tracking risk while trying to beat benchmark
Information ratio ⇒ mean active return / tracking risk (efficiency with which tracking risk deliver active return)
4 PASSIVE EQUITY INVESTING
return (active investment underperform after-cost basis)
small cap (heavy transaction cost) & unfamiliar overseas markets
4.1 Equity Indices
To perform technical analysis & β calculation
returns are calculated, determine stock index’s characteristics
L/S = Long-Short
IR = Information Ratio CSP = Core-Satellite Portfolio
Trang 24.1.1 Index Weighting Choices
price
shares
buying one share of each index component
Simple to construct & can go back far into the past
investing same proportion as each index component in index
Self corrects for stock splits & reverse stock splits etc
Float weighted index ⇒ subcategory
factor
return to avg dollar invested passively
(representative & minimum tracking error)
equal $ investment in each index component
Weighting Scheme Biases
(can change through splits, stock dividends etc)
(mature & overvalued companies)
restriction (e.g maximum holdings)
transaction cost)
4.1.2 Equity Indices: Composition & Characteristics of Major Indices
Price weighted & equal weighted indexes are very few in numbers now days
Indices
Committee-determined indices Algorithm (formula based)
Low turnover (low transaction cost & tax)
away from intended segment
High cost & taxes
Fund must evaluate tradeoff b/w transaction cost & difference in return premiums
Trang 3
4.2 Passive Investment Vehicles
4.2.1 Investment in indexed portfolio
Long position in cash & long position in futures
Long position in cash & long position in Swap
Mutual Funds Exchange Traded Funds Trading frequency Trade at NAV once at market close Trade in public market anytime during trading day
Cost of providing liquidity Yes No, due to in-kind creation/redemption
Shareholder accounting expense Yes No fund level shareholder accounting
Difference b/w Indexed Mutual Funds & ETFs
Indexed institutional portfolios (separate or pooled) are cost efficient than MF & ETFs
& custody expense
Separate or Pooled Accounts
Indexing a Portfolio
than 1000 & liquid
weighted index, is self rebalancing, trading required only for reinvestment
of dividends & to reflect changes in index composition
return on index (administrative cost, transaction cost, cash drag)
/cells (industry value, growth etc)
Place each stock into a cell & match cell weight into portfolio as cell weight into index
error
index fund from non-diversified index
index & individual securities risk exposures are measured & minimize the tracking error
among factors (advantage)
Risk change over time & model is based on historical data
error than stratified sampling when used in combination with full replication
4.2.2 Equity Index Futures
Trang 44.2.3 Equity Total Return Swaps
Motivated by different tax treatment of shareholders in different countries or to acquire exposure to an asset class for strategic/tactical asset allocation (less cost of rebalancing)
5 ACTIVE EQUITY INVESTING
5.1 Equity Styles
Focus is low share price relative to earning or BV
High earning growth companies are key considerations
Intermediate grouping for investments (neither value nor growth)
5.1.1 Value Investment Styles
causing in multiple & stock price
Growth investing contains risk of contraction in earnings &
multiples
Low P/E ⇒ invests in stock with low price hoping industry &
stock will recover & P/E will improve
Contrarian ⇒ investment in very depressed industries usually P/B < 1
Yield investor ⇒ focus on high current & future dividend yield (component of total return)
5.1.2 Growth Investment Styles
Focus on future EPS growth rate & major risk is that growth will not take place & price will
Consistent growth ⇒ invest in companies with long growth history
Earning momentum ⇒ higher quarterly year-over-year earnings growth but less sustainable
expansion
Trang 55.1.3 Other Active Management Styles
falls (growth / value)
Drawback ⇒ if portfolio achieves market like return, indexing or enhanced indexing presents a lower cost alternative
Market oriented with value biased (hold well diversified portfolios)
Market oriented with growth biased (hold well diversified portfolios)
Growth-at-reasonable price ⇒ investor favors companies with above avg growth with conservative valuation (portfolios are less diversified than other growth investors)
Style rotators ⇒ invest in most favored near term style
Market Capitalization
stocks (less research)
of small cap
than large cap (opportunities exist)
cap
More financial stability
superior analysis
5.1.4 Techniques for Identifying Investment Styles
Return based style analysis Holding based style analysis
of indices
Mutually exclusive & exhaustive
β on indices are nonnegative & sum to 1
Normal benchmark ⇒ benchmark with same systematic risk exposure as manager’s portfolio
R2 determine style fit & 1-style = selection
return
characteristics & draw overall style conclusion
low P/E, P/B & high dividend yield( vice versa for growth) & market oriented has valuation close to market avg
portfolio ⇒ larger weight in utilities & finance sector
are higher
Two approaches to style analysis: Advantages and Disadvantages
Returns-based style
analysis
portfolio characterizations
conclusions
Holdings-based
styles analysis
than returns-based analysis
security selection
Requires specification of classification attributes for style;
different specifications may give different results
Trang 6
5.1.6 The Style Box
Style box is used for looking at a style
(value, core & growth)
firms
5.1.7 Style Drift
5.2 Socially Responsible Investing
Consider ethics, social & religious concerns while taking investment decisions
Negative stocks screens ⇒ reduce investment universe
Positive SRI Screens ⇒identify companies with ethically desirable characteristics
cap stocks
objective & constraints
style analysis
5.3 Long-Short investing
constraints (short selling)
hold two alphas
Portable alpha ⇒ added to variety of systematic risk exposures
Pair trade ⇒ long / short in two single industry firms’ stocks by equal currency amounts (almost zero β, only firm specific risk)
Leverage used in L/S strategy magnifies risk & return
If the price of short position tend to rise, loss can be unlimited
5.1.5 Equity Style Indices
Overlap ⇒ some securities may be assigned in part to both value & growth
No overlap ⇒ security is assigned to either value, growth or market oriented
Buffering ⇒ rules for maintaining the previous stock assignment when stock has not clearly moved to a new style
Trang 75.3.2 Equitizing a Market-Neutral Long-Short Portfolio
ETF is an alternative to futures & cost effective way of equitizing & de-equitizing
benchmarked against relative index
5.3.3 The Long-Only Constraint
insights” over long only portfolio
(can’t take short position)
5.3.4 Short Extension Strategies
100/0 & 30/30 they are not (consider two portfolios)
5.4 Sell Disciplines/Trading
Strategy of Substitution Deteriorating Fundamentals Rule Driven
opportunity by considering transaction cost & taxes
discipline
Valuation level (e.g if P/E reaches historical avg.)
Target price sell discipline
Reduce or eliminate a position if company’s business prospects are expected to deteriorate
These sell disciplines are not mutually exclusive
5.3.1 Price Inefficiency on the Short Side
alpha than long side)
Short positions difficult to obtain (e.g find lender)
to be overvalued rather than undervalued)
commissions & potential buyers > sellers & short sellers
sell recommendations [against standard I (B)]
Trang 86 SEMIACTIVE EQUITY INVESTING
managing portfolio risk exposure
Highest IR as compared to indexing & active management
Basic Forms
return through something other than equity investments
through duration management
Identify overvalued & undervalued stocks & outperform through stock selection
data,will not work if economy changes
Fundamental Law of Active Management
Where IC = information coefficient (effectiveness of investment insight)
Breadth = no of independent active investment decision
Higher the ratio, the better it is
7 MANAGING A PORTFOLIO OF MANAGERS
classes to use & how to invest within each asset class
risk
Where
= expected utility of active return of manager mix
= expected active return
⋌ = active risk aversion
= variance of active return
have the skill to select outperforming managers
performance is judged relative to benchmark, which is difficult to outperform
(active risk limitation by institutional investors)
Where
ℎ = weight assigned to ith manager
= active return of ith manager
ଶ
ଶ if returns are correlated include covariance term under square root sign
Trang 97.1 Core-Satellite
Core-satellite portfolio ⇒ consists of a core holding (index & semi active) &
satellite (active managers)
other heuristic
may have different benchmarks
Decomposition of Active Return
True Active Return Misfit Active Return
Manager’s return - manager’s normal benchmark
Manager’s normal benchmark - investor’s benchmark
Decomposition of Active Return
True Active Return Misfit Return
=
Total active risk = ! ᇱ "ଶ+! ᇱ "ଶ#
Completeness fund ⇒ when added to active managers’ positions, establishes an overall portfolio with same risk exposure as investor’s overall equity benchmark
losing part of true active return
7.2 Completeness Fund
∝ $Long on Japanese manager portfolio !TOPIX index"&
Long active equity portfolio ⇒ provides both α & β exposure
Market neutral L/S ⇒ can better manage α & β (can use portable α in asset class outside β asset class)
not really be market neutral
7.3 Other Approaches: Alpha & Beta Separation

managers are talented & truly add value
etc) & quantitative (comparison with peers, style orientation etc) factors
8.2 The Predictive Power of Past Performance
result”
manager exhibiting consistent underperformance from benchmark not likely to be selected)
8.3 Fee Structures
Fee cap ⇒ upper limit to total fee (limit manager from high risk)
High water mark ⇒ provision requiring cumulatively generated outperformance since last performance-based fee paid
Symmetric incentives fees ⇒ reduce (poor performance) as well as increase (good performance) compensation (better align manager &
plan sponsor interest) Manager’s revenue volatility
One-sided performance based fee ⇒ conveys a call option to investment manager & value is determined through option pricing model
