Expected Return Calculation in Portfolio Management

Expected return is a statistical measure that helps investors assess the potential profitability of an investment. It is calculated by taking each possible return, multiplying it by the likelihood of that return occurring (its probability), and then summing these products. This method provides a weighted average of all possible returns, reflecting their potential impact on overall performance.

To find the expected return, multiply each possible return by its probability: (0.40 * 0.15) + (0.60 * 0.08). This results in 0.06 + 0.048, which totals 0.108 or 10.8%. Thus, the expected return is 10.8%.

In a two-asset portfolio, the expected return is calculated by taking the weighted average of the returns of each asset. The weights reflect the proportion of the total investment allocated to each asset, indicating how much influence each asset's return has on the overall portfolio return.

To calculate the expected return of the portfolio, multiply the expected return of each stock by its weight in the portfolio. For Stock A, 60% of 12% equals 7.2%, and for Stock B, 40% of 8% equals 3.2%. Adding these together gives an expected return of 10.4%.

The historical return model relies on past performance to predict future returns. By analyzing the average returns over a defined timeframe, it provides a basis for estimating expected returns, allowing investors to make informed decisions based on historical data trends. This approach assumes that past performance can be indicative of future results.

Expected return is calculated using the probability-weighted method by considering the probabilities of each outcome and the returns associated with those outcomes. Standard deviation, while important for assessing risk, does not directly influence the expected return calculation, which focuses solely on the probabilities and returns of different scenarios.

In the Capital Asset Pricing Model (CAPM), Rf represents the risk-free rate, which is the return expected from an investment with zero risk. This rate serves as a baseline for comparing the returns of riskier investments, helping to determine the expected return based on the asset's systematic risk (beta) and the market risk premium.

Using the Capital Asset Pricing Model (CAPM), the expected return is calculated with the formula: Expected Return = Risk-Free Rate + Beta × (Market Return - Risk-Free Rate). Plugging in the values: 3% + 1.5 × (10% - 3%) = 3% + 10.5% = 13.5%. Thus, the expected return on the stock is 13.5%.

In the Capital Asset Pricing Model (CAPM), a stock with a beta of 1.0 indicates that it has the same level of systematic risk as the overall market. Therefore, its expected return aligns with that of the market portfolio, which represents the average return of all risky assets in the market.

In the dividend discount model, the expected return is calculated by considering the current stock price, the dividends received, and the growth rate of those dividends. The growth rate reflects how much the dividends are expected to increase over time, which directly influences the overall return an investor can anticipate from the stock.

Using the Gordon Growth Model, the expected return is calculated as the dividend yield plus the growth rate. Here, the dividend yield is $2 divided by the stock price of $50, which is 4%. Adding the growth rate of 5% gives a total expected return of 9%.

In the Capital Asset Pricing Model (CAPM), beta measures a security's sensitivity to market movements. A higher beta indicates greater volatility and risk compared to the market. Investors typically require a higher expected return as compensation for taking on this additional risk, thus establishing a direct relationship between beta and expected return.
