How a long put works

A long put gives its holder the right to sell the underlying at the strike price through expiration. Its value can rise as the stock falls, while the premium paid defines the maximum loss if the put expires worthless.

Modeling downside scenarios

The projected chart and table show how different underlying prices, future dates, and implied-volatility assumptions affect the put's theoretical price and the total position profit or loss.
