Trang 4Structuring a Stock Portfolio : The Objective
Semantics are important in any statement
of investment objectives.
The four main portfolio objectives are
In a world with taxes, one dollar in capital
gains is worth more than one dollar in
income.
The overriding investment objective is
utility maximization.

Trang 7Structuring a Stock Portfolio : Asset Allocation
An asset class refers to a broad category
of investments.
U.S equities, foreign equities, bonds, and
cash are four widely used asset classes.
The relative distribution of funds across
asset classes is called asset allocation.

Trang 9Structuring a Stock Portfolio : Active vs Passive Management
A strategy of passive management is one in which, once established, the portfolio is
largely left alone.
An active management policy, in contrast,
is one in which the composition of the
portfolio is dynamic.
Trang 10What’s Wrong with Buy and Hold ?
With a passive buy and hold strategy
(a naive strategy), investors simply select their investments and hang on
to them
Portfolio managers often fail to outperform
a passive buy and hold strategy.
When tested statistically, trading systems
also do not have a good long-term batting average.
Trang 11The Costs of Revision
There are costs to revising a portfolio.
Trading fees : Historically, stock
commissions are a function of the number
of shares and the dollar amount involved.
Even relatively simple portfolio revisions
take up management time.
Selling securities can involve tax
Window dressing refers to largely cosmetic
portfolio changes made near the end of a
reporting period.
Trang 12Portfolio Rebalancing
Rebalancing a portfolio is the process of
periodically adjusting the portfolio so that certain original conditions of the portfolio are maintained.
In a constant proportion portfolio,
adjustments are made so as to maintain the relative weighting of the portfolio
components as their price change.
to maintain beta at a prespecified level
This method is not commonly used now.

Indexing : Some funds seek to mirror the
performance of a market index such as the S&P 500 or the Dow Jones Industrial
Average.
Dollar cost averaging : The idea is to invest
a fixed amount on a regular interval into the same security, regardless of current market conditions.

The context of dollar cost averaging is one
of the few times in finance when the
mean considers reciprocals of values
rather than the values themselves.
Trang 20 Option overwriting refers to the creation
and sale of stock options in conjunction
with a stock portfolio.
The most common purpose is to generate
additional portfolio income.
The second motivation for writing options
is to permit the purchase or sale of stock at
a better-than-market price.
Trang 21Writing Options to Generate Income
When investors write call options against
stock they already own, the call is said to

Trang 24Overwriting : Improving on the Market
Improving on the market involves writing
deep-in-the-money put or call options that have “substantial” intrinsic value.
Selling stock:
Current XYZ stock price = $116
Write $100 call premium @ $18
If option is exercised,
total income = $100 + $18 = $118
> income without overwriting = $116
Trang 25Overwriting : Improving on the Market
Buying stock:
Current Intel stock price = $67.20
Write $75 put premium @ $9
If option is exercised,
total cost = $75 - $9 = $66
< cost without overwriting = $67.20
Deep-in-the-money options can be used to
improve a buying or selling price at the
cost of a slight increase in risk.
Trang 26Portfolio Protection
Portfolio protection basically involves adding
adding components to a portfolio such that
a floor value is established below which the value of the portfolio will not fall.
Writing covered calls provide downside
protection up to the amount of the premium.
If an investor owns shares of a particular
stock (long stock position) and buys a put on that same stock (long put position), the put is called a protective put.

Trang 29Portfolio Protection
Using index options : An index put can
protect a diversified stock portfolio against
a market downturn If market prices
decline, a gain on the puts can largely
offset the losses on the stock portfolio.

Trang 31Portfolio Protection
Using index futures contracts : A short
futures position can help offset a long
stock position If the market falls, a gain in the futures market can largely offset the
loss on the stock portfolio, and vice versa if the market rises.
