Expected Value Pricing Interview Questions
Expected value pricing interview questions for turning expected payoff, cost, and uncertainty into a fair toy price.
Candidates answering price-this-bet, price-this-contract, and fair-value prompts.
Price starts with expected payoff
In a toy risk-neutral pricing prompt, the first fair-price estimate is the expected payoff before any extra costs or constraints.
Use net value for the decision
Expected payoff and expected profit are different. If you pay a price to enter, subtract that price from the expected payoff to get net expected value.
Concrete example
If a binary payoff pays 10 with probability 30 percent and 0 otherwise, the expected payoff is 3. A price below 3 is positive EV under the simplified assumptions.
Fair price is not always bid price
A fair value can be adjusted downward for uncertainty, risk limits, transaction costs, or the need for a margin of safety.
Compare to market-implied price
When a market or interviewer gives a quoted price, compare that quote with your expected-value price and explain the source of any gap.
Common mistakes
Candidates often quote the expected gross payoff without saying whether it is a fair price, maximum bid, or expected profit after paying the price.
