5.2 Risk and Return Flashcards
Return ON Investment (ROI)
Return - (minus) Amount Invested
Rate of Return
Return on Investment/
Amount Invested
Two Basic Forms of Risk
Systematic Risk (Market Risk): Risk faced by ALL firms. Economy, etc. It is UNDIVERSIFIABLE
Unsystematic Risk (Non-Market or Company (Specific) Risk) : Diversifiable through Portfolio diversification
Other Forms of Risk (not Systematic/Unsystematic)
PIF-C
PIF-L
Credit Risk: Risk ISSUER OF DEBT will default
Foreign Exchange Risk: Risk FX will be affected by Exchange Rates
Interest Rate Risk: Risk Investment will fluctuate in value due to interest rate change
Industry Risk: risk to INDUSTRY. Airlines due to fuel prices.
Political Risk: probability of Risk due to govt action. (Expropriation). Can be reduced by making foreign entity dependent on Domestic corp for Technology, etc.
Financial Risk: Risk based on markets (due to interest maybe)
Purchasing Power Risk: General increase in cost will reduce what can be bought for same dollars
Liquidity Risk: security can’t be sold on short notice for its market value
Risk Averse v Risk Neutral v Risk Seeking
Averse: Disutility of Loss exceeds Utility of Gain
Neutral: Disutility of Loss equals Gain
Seeking: Utility of Gain exceeds Disutility of Loss
List of Financial Instruments by Risk (Low to High)
T12S,
T Bonds First Mortgage Bonds 2nd Mortgage Bonds Subordinated Debentures Income Bonds Preferred Stock Convertible Preferred Stock Common Stock
Indifference Curve
An investor curve that shows investment returns on X axis. Risk on Y axis. Different risk and returns are plotted. ON the same curve it doesn’t matter which is selected. Steeper the Curve, more risk averse.
Maturity Matching
Making sure securities will not have to be sold unexpectedly. Maturity of Funds coincides with the need for the funds.
Uncertain Cash Flows of an Investment=
Cash Flows Certain
Then need to consider Marketability and Market Risk
Certain = Maturity is most important
Hedging
Offsetting Commitments to minimize risk of adverse price movements
Natural Hedge
Buying different investments whose performance cancels each other (Insurance is a natural hedge)
Pair Trading: long and short positions
Sometimes: Stocks and Bonds
Futures Contracts
- to hedge commodities
- agreement to buy/sell commodities at a price in a later month
- Can be bought/sold on margin (risky..leverage)
Expected Rate of Return
Sum of all probabilities by Weight
Standard Deviation (and risk)
The wider the standard deviation (variance) the great the risk
Security Risk (individual) v Portfolio Risk
- Should evaluate Risk based on portfolio not individual stock
- Risk is NOT average of the Standard Deviations of the stocks. because stocks are imperfectly correlated, combining stocks is LESS than the Average of the Standard Deviations.
Correlation Coefficient
Degree to which any TWO variables are correlated 1.0 to - 1.0.
- Perfect negative correlation = perfect hedges of each other (risk ELIMINATED)
Covariance
Covariance of a Two Stock Portfolio =
Correlation Coefficient x Std Deviation1 x Std Deviation2
