What Is a Short Put?
A short put is an options strategy where you sell (write) a put option on Pluang, collecting a premium upfront in exchange for taking on the obligation to buy the underlying stock or ETF at the strike price if the buyer exercises the contract. Traders open a short put when they expect the underlying's price to stay flat or rise, since the position profits as long as the price stays at or above the strike price through expiry. Maximum profit is capped at the premium received, realized in full if the option expires worthless because the buyer has no reason to exercise. Maximum loss is large but not unlimited — it is capped at the strike price minus the premium received, since the underlying's price cannot fall below zero, though a sharp price drop can still force you to buy the asset well above its current market value. Because Pluang's options are American-style, assignment risk exists at any point before expiry, not only on the expiry date itself.
- How the position is opened: You sell a put contract instead of buying one. Pluang credits the premium to your balance immediately, and that premium is yours to keep regardless of what happens next — it's the entire source of profit on this trade.
- The obligation you take on: By selling the put, you agree to buy the underlying at the strike price if the option is exercised. This is why a short put is typically opened with enough available balance or collateral to cover that potential purchase.
- Best-fit market view: Neutral-to-bullish. A short put is commonly used by traders who wouldn't mind owning the underlying asset at the strike price anyway, effectively getting paid a premium while waiting for a target entry price.
- Assignment timing: Because Pluang's options are American-style, the buyer can exercise at any time before expiry, not just on the expiry date — so a short put can be assigned early if the price moves sharply against the position.
- Access requirement: Trading options on Pluang, including short put strategies, requires completing Global & Yield Asset Verification, the KYC tier that unlocks US Stocks, ETFs, and Options.

Q: What is the maximum profit on a short put?
The maximum profit on a short put is the premium received when opening the position, and nothing more. This full amount is realized only if the underlying's price stays at or above the strike price all the way through expiry, since the buyer has no financial reason to exercise an option that's worth less than what they'd pay you for the underlying. If the price dips below the strike even briefly but recovers by expiry, the outcome depends on whether early assignment occurred in the meantime.
Q: What is the main risk of a short put?
The main risk is a large — though capped — loss if the underlying's price falls sharply below the strike price. Since a short put obligates you to buy the asset at the strike price regardless of how far the market price has dropped, the loss grows as the gap widens. The loss is capped only because the underlying can't trade below zero; in the most extreme case, your maximum loss equals the strike price minus the premium you already collected.
Q: When should I consider using a short put?
A short put fits a neutral-to-bullish view, typically used when you expect the underlying to hold steady or rise and you're comfortable being assigned the asset at the strike price if it doesn't. Some traders use it deliberately as a way to potentially acquire a stock or ETF at a target price while collecting premium income in the meantime, rather than placing a limit buy order that pays nothing while waiting.
Q: Can my short put be assigned before expiry?
Yes. Pluang's options are American-style, which means the buyer holding the corresponding put can exercise it at any point before the expiry date, not only on expiry day itself. This makes early assignment a real possibility for a short put, especially if the underlying's price falls well below the strike price before expiry, rather than only being a risk you face on the final trading day.
