Long Put Options Strategy Guide
By OptionClaws, VirWare LLC · Updated 2026-08-23
A long put gives you the right, but not the obligation, to sell 100 shares of the underlying at the strike price before expiration. It is the cleanest way to profit from a decline, or to insure shares you already own, with risk capped at the premium paid. Unlike shorting stock, a long put cannot generate a loss beyond its cost and needs no borrow, which is why it is the standard retail hedge and the standard defined-risk bearish bet.
Key takeaways
- A long put is the right to sell 100 shares at the strike until expiration
- Max loss is the premium paid; max profit is strike minus premium if the stock goes to zero
- Breakeven at expiration is strike minus premium
- Puts are usually priced richer than equivalent calls because of skew
When it makes sense
- You expect a meaningful drop before expiration
- You want defined-risk downside exposure without the unlimited risk of shorting shares
- You are hedging a long stock position through an earnings report or other event
- Implied volatility is low enough that the protection is reasonably priced
How it works
Buy one put at your chosen strike and expiration. The premium paid is your maximum loss. At expiration the put is worth the greater of zero and the strike minus the stock price, so breakeven is the strike minus the premium. The put gains value as the stock falls and, before expiration, as implied volatility rises, which often happens at the same time. As a hedge, one put per 100 shares held caps the position's loss at roughly the difference between your cost basis and the strike, plus the premium.
Risk and reward
Maximum loss: the premium paid, realized if the stock finishes at or above the strike. Maximum profit: the strike minus the premium, times 100, reached only if the stock goes to zero, so it is large but bounded. Breakeven: strike minus premium. Because downside moves tend to be fast and volatility tends to rise when stocks fall, a long put often gains more quickly on a drop than a long call does on an equivalent rally.
Greeks and volatility
Delta is negative: a 0.40-delta put (often written as -0.40) behaves like being short about 40 shares. Gamma is positive, so the put's delta grows more negative as the stock falls. Theta is negative and accelerates into expiration. Vega is positive, and because implied volatility usually rises in a sell-off, a long put benefits twice on a sharp drop. The flip side is skew: out-of-the-money puts carry higher implied volatility than calls the same distance away, so you pay more for crash protection than for upside.
Managing the trade
Close before expiration to capture remaining time value rather than exercising. If you own the shares and the put is deep in the money at expiration, exercising delivers the shares at the strike, which is the hedge doing its job. Early exercise is your option as the buyer, never a risk. For a standalone bearish trade, set a profit target in advance and consider rolling down (selling the current put, buying a lower strike) to bank gains once the stock has fallen. Hedges are often financed by selling a call against the shares, turning the position into a collar.
Worked example
Stock at $80. Buy the 45-day $75 put for $1.80, a $180 outlay. Breakeven is $73.20. If the stock falls to $65 by expiration, the put is worth $10.00 and you sell it for $1,000, an $820 profit. If the stock finishes at $74 the put is worth $1.00 and you lose $80. At or above $75 the put expires worthless and you lose the full $180.
What to screen for
Rank puts by the probability of finishing below breakeven and by the debit as a percent of the stock price. Check implied volatility rank: buying puts when volatility is already elevated means paying up for protection that may deflate. For hedges, filter by days to expiration that cover the event you are worried about plus a margin, and insist on tight spreads and real open interest so the hedge can be unwound cleanly.

Frequently asked questions
- What is the maximum profit on a long put?
- The strike minus the premium paid, times 100. It is reached only if the stock goes to zero, so the profit is bounded but can be many times the premium.
- Is buying a put the same as shorting the stock?
- No. A short stock position has unlimited risk and needs shares to borrow. A long put caps your loss at the premium and expires, so it is a time-limited, defined-risk way to be bearish.
- How many puts do I need to hedge my shares?
- One put per 100 shares for a full hedge at the strike. The strike sets the floor: a $75 put on shares bought at $80 limits the loss to about $5 per share plus the premium.
- Why are puts more expensive than calls?
- Volatility skew. Markets price a higher implied volatility into out-of-the-money puts because crashes are faster and more violent than rallies, and because there is steady hedging demand for puts.
