Selling an Option When Its Expected Payoff Is Zero
Summary
This brief exchange asks what price to charge for an option whose expected payoff is zero. The reply gives a minimal market-based answer: a seller would accept the smallest positive amount buyers are willing to pay. It treats the question as one of willingness to pay rather than deriving a fair value from a pricing model.
No assumptions are specified about the probability distribution, risk preferences, discounting, hedging, or whether “expected payoff” means a physical or risk-neutral expectation. The answer therefore does not establish that a zero expected payoff implies a particular option price. In practice, valuation also depends on risk, market prices, and the pricing framework; this exchange offers a concise intuition, not a general pricing method.
Key ideas
- The reply frames the sale price as the positive amount buyers are willing to pay.
- A zero expected payoff alone does not determine an option’s market value.
- The exchange specifies no probability measure, discounting convention, or risk assumptions.
- The answer is an intuition rather than a complete option-pricing framework.
