At NorthBridge Capital, an interviewer asks you to explain basic asset pricing using simple probability and statistical reasoning rather than finance jargon. You are given a one-period risky asset and asked to quantify its value and test whether its average return appears meaningfully different from a benchmark.
A stock will be worth different amounts in one year depending on the state of the economy. Use the state probabilities to compute the asset's expected payoff, expected return, and risk. Then use a small sample of historical annual returns to test whether the stock's mean return differs from a 6% benchmark return.
