3. Selecting a portfolio strategy

4.Selecting the assets Picking securities to build your portfolio Efficient portfolio – provides the greatest

expected return at a given level of risk

Actives - use information and forecasting techniques to seek a better performance

Passives – diversification Structured – match the funds received from

contributions to the future liabilities

Risk and Return Two key observations emerge

There is a reward for bearing risk, and at least on average, that reward has been substantial.

Greater rewards are usually accompanied by greater risks.

In summary, high risk should compensated by high return

Page 14: w01-02-Introduction Risk vs Return

Return Components

Returns consist of two elements:– Periodic cash flows such as interest or

dividends (income return)– Price appreciation or depreciation (capital

gain or loss)

Total Return =Yield +Price Change

Measuring Returns

For comparing performance over time or across different securities

Total Return is a percentage relating all cash flows received during a given time period, denoted CFt +(PE - PB), to the start of period price, PB

Page 16: w01-02-Introduction Risk vs Return

Example: Calculating Returns Suppose you invested $1,000 in a stock at

$25 per share. After one year, the price increases to $35. For each share, you also received $2 in dividends.

Total dollar return = 48% of $1,000 = $480 At the end of the year, the value of your

$1,000 investment is $1,480.

$2+($35-$25) = 48%

Total Return can be either positive or negative– When cumulating or compounding,

negative returns are problem

A Return Relative solves the problem because it is always positive

To measure the level of wealth created by an investment rather than the change in wealth, need to cumulate returns over time

Cumulative Wealth Index, CWIn, over

n periods, =

investment in two consecutive years are 1.48 and 0.95, assume CW0 is $1000, what is Cumulative Wealth Index, CWI2, over these 2 years?

Measures Describing a Return Series Arithmetic mean, or simply mean,

Page 22: w01-02-Introduction Risk vs Return

Arithmetic Versus Geometric

Arithmetic mean does not measure the compound growth rate over time– Does not capture the realized change in

wealth over multiple periods– Does capture typical return in a single

period

Geometric mean reflects compound, cumulative returns over more than one period

Adjusting Returns for Inflation

Returns measures are not adjusted for inflation

– Purchasing power of investment may change over time

– Consumer Price Index (CPI) is possible measure of inflation

Measuring Risk

Risk is the chance that the actual outcome is different than the expected outcome

Standard Deviation measures the deviation of returns from the mean

Financial Risk– Tied to debt

financing

Liquidity Risk– Marketability with-

out sale prices

Exchange Rate Risk

Country Risk– Political stability

Risk Sources Interest Rate Risk

– Affects income return

Market Risk– Overall market

effects

Inflation Risk– Purchasing power

Risk Types

Two general types:– Systematic (general) risk

• Pervasive, affecting all securities, cannot be avoided

• Interest rate or market or inflation risks

– Nonsystematic (specific) risk• Unique characteristics specific to issuer

Total Risk =General Risk +Specific Risk

expected for taking additional risk

Equity risk premium is the difference between stock and risk-free returns

The Lesson

The greater the potential reward, the greater the risk.
