What Is a Naked Put?
A naked put is a put option sold without a protective offsetting position. It is also called an uncovered put. The seller collects premium but may be required to buy the underlying security at the strike price if assigned.
The risk is that the underlying price falls sharply. The seller can be forced to buy an asset for more than its market value. The maximum loss is large, though not unlimited, because the underlying price cannot fall below zero.
Key Takeaways
- A naked put is a short put position without a hedge that limits downside risk.
- The maximum gain is the premium received.
- The seller can face large losses if the underlying security declines sharply.
- Uncovered put writing usually requires options approval, margin capacity, and careful risk controls.
How the Trade Works
A put option gives the buyer the right to sell the underlying security at a strike price. The put seller has the obligation to buy if assigned. If the underlying stays above the strike price, the option may expire worthless and the seller keeps the premium.
If the underlying falls below the strike price, the seller's position loses value. Assignment may require buying shares at the strike price even though the market price is lower. The premium received reduces the loss but does not eliminate the exposure.
Naked Put Risk Profile
Feature | Naked Put |
|---|---|
Maximum gain | Premium received. |
Maximum loss | Strike price minus premium, if the underlying falls to zero. |
Market view | Usually neutral to bullish on the underlying. |
Primary risk | A sharp drop in the underlying price. |
Account requirement | Typically requires margin and options approval. |
Cash-Secured Versus Naked
A cash-secured put is different from a naked put because the seller holds enough cash to buy the shares if assigned. The economic exposure can still be meaningful, but the cash reserve reduces funding risk and margin pressure.
A naked put can become dangerous when the seller relies on margin, overconcentrates in one underlying, or treats premium income as low-risk yield. A fast decline can create losses and margin calls at the same time.
The Bottom Line
A naked put is a premium-collection strategy with substantial downside risk. It can look conservative when markets are calm, but the obligation to buy after a sharp decline can create losses far larger than the premium received.
