Put Option Interview Intuition
Put option interview intuition for downside payoff shapes, max(K-S,0), expected payoff scenarios, and sign mistakes.
Candidates discussing option-style payoffs and risk.
Put-like payoff
A put-like payoff benefits when the underlying value falls below a strike or threshold.
Max expression
The common payoff shape is max(K - S, 0): positive below the strike K and zero above it.
Concrete example
If K is 50 and S ends at 40, the toy put payoff is 10. If S ends at 55, the payoff is 0.
Risk intuition
Put-like payoffs can be used in toy prompts to discuss downside exposure, but that does not make them real hedging advice.
Expected payoff
As with any payoff, compute the value in each state and average by probabilities under the prompt model.
Common mistakes
Candidates often reverse S minus K and K minus S. Draw a quick payoff table to keep the sign straight.
