Study Notes
Risk and Return Fundamentals
- Key financial decisions involve evaluating risk and return.
- Risk: Measure of uncertainty in investment returns; variability in returns associated with an asset.
- Return: Total gain or loss from an investment over a specific period.
- Rate of return formula: ( r_t = \frac{C_t + (P_t - P_{t-1})}{P_{t-1}} ).
Understanding Risk
- Risk preferences categorize investors as:
- Risk Averse: Require higher returns for increased risk.
- Risk-Neutral: Prefer higher returns regardless of associated risks.
- Risk-Seeking: Favor riskier investments even with lower expected returns.
Single Asset Risk Assessment
- Scenario analysis evaluates risk using various possible outcomes: pessimistic, most likely, and optimistic.
- Range: Calculated as the difference between optimistic and pessimistic returns.
- Probability distributions associate probabilities with potential outcomes, helping assess risk.
Risk Measurement
- Standard deviation (( \sigma_r )): Indicates dispersion around the expected return; higher standard deviation signifies greater risk.
- Coefficient of Variation (CV): Measures the relative dispersion relative to expected return; useful for comparing different assets.
Portfolio Risk
- Portfolio risk assessment considers existing assets when evaluating new investments.
- Efficient Portfolio: Aims for maximum returns with a given level of risk.
- Portfolio return: Weighted average of individual asset returns, accounting for each asset's percentage in the portfolio.
Correlation and Diversification
- Correlation: Indicates the relationship between two assets; can be positive, negative, or uncorrelated.
- Diversification reduces overall portfolio risk by combining assets with low correlations.
International Diversification
- Adding international assets tends to improve portfolio performance by reducing correlation with domestic market movements.
- Unique risks in international investing include currency and political risks.
Capital Asset Pricing Model (CAPM)
- CAPM: Links risk (beta) and return, quantifying expected additional return per unit of risk.
- Total risk consists of diversifiable (firm-specific) and non-diversifiable (market) risk.
- Beta coefficient measures an asset's non-diversifiable risk in relation to market movements.
CAPM Formula
- ( r_j = R_F + [b_j \times (r_m - R_F)] )
- Historical returns and market performance guide the estimation of required returns.
Security Market Line (SML)
- Visual representation of CAPM showing the required return across various levels of non-diversifiable risk (beta).
- Shifts in SML can occur due to changes in inflation or shifts in risk aversion among investors.
Important Considerations
- CAPM relies on historical data, which may not accurately predict future variability.
- Assumes market efficiency, which while idealistic, is supported by observations in active markets like the NYSE.
