Final answer:
The best guess for the rate of return on the stock is -7.9%.
Step-by-step explanation:
The expected rate of return on a stock can be calculated using the formula:
Expected Return = Risk-Free Rate + Beta * (Market Return - Risk-Free Rate)
In this case, the beta of the stock is 2.1 and the expected rate of return is 32%. If the market return is 13% below expectations, we can calculate the rate of return on the stock as follows:
Rate of Return on Stock = Risk-Free Rate + 2.1 * (Market Return - Risk-Free Rate)
Let x be the rate of return on the stock:
x = 0.32 + 2.1 * (0.13 - 0.32)
Simplifying the equation, we get:
x = 0.32 + 2.1 * (-0.19)
x = 0.32 - 0.399
x = -0.079
So, the best guess for the rate of return on the stock is -7.9%.
