Selling a Put Option: Meaning, Example, Payoff, and Risk
Selling a put option means collecting premium while accepting downside obligation if the underlying falls below the strike.
Options trading involves significant risk. The examples here are educational and are not recommendations to buy or sell any security or derivative contract.
A short put can look comfortable because the market often does not fall far enough. The danger is forgetting that a fast fall can turn premium collection into a large loss.
Start with the key takeaways, then look at the example table. Do not rush to the setup name. In option selling, the real test is what happens when the trade is wrong: margin, volatility, liquidity, and the exit rule matter more than the premium shown on screen.
Key takeaways
- A put seller receives premium and takes downside risk.
- Maximum profit is usually limited to premium.
- Loss grows as the underlying falls below breakeven.
- Cash-secured puts are different from leveraged naked puts.
- Hedged put spreads make the loss easier to define.
What selling a put means
Selling a put option means the seller receives premium from a buyer who wants the right to sell the underlying at a strike price.
If price stays above the strike, the put may expire worthless. If price falls below the strike, the seller carries the loss linked to that move.
Short put payoff example
Assume a stock is at 100 and a trader sells a 95 put for 2.
| Stock at expiry | Put value | Seller result |
|---|---|---|
| 100 | 0 | +2 premium |
| 95 | 0 | +2 premium |
| 93 | 2 | Around breakeven |
| 85 | 10 | -8 before costs |
| 70 | 25 | -23 before costs |
Breakeven is strike minus premium received, before costs.
Why traders sell puts
Some traders sell puts to express a bullish or neutral view. Others use cash-secured puts to potentially buy stock at an effective lower price.
The risk is that the market can fall much more than expected, especially during panic or news events.
Cash-secured vs naked puts
A cash-secured put keeps enough capital to buy the shares if assigned. A naked put uses margin and can pressure the account when price falls.
For index options such as NIFTY, assignment mechanics differ from stock options, but the payoff risk remains real.
What to check before selling
Check breakeven, worst-case loss, margin, event risk, and whether the trade is part of a defined-risk spread.
If the plan depends on adding more size after a fall, the risk is probably not understood.
