Selling a put can be a way to seek stock ownership at a chosen strike while receiving a premium. It also creates an obligation to buy the shares if assigned—even if the company's outlook deteriorates or the market price falls far below that strike.
Cash-secured and uncovered puts
A cash-secured put reserves enough cash to pay for the stock if assigned. An uncovered put does not fully reserve that purchase amount and relies on applicable margin arrangements. Both have the short put's downside exposure; reserving cash addresses funding, not a collapse in the stock's value.
For a standard U.S. equity put, one contract normally represents 100 shares. The full assignment payment is strike × 100 per contract. Check adjusted deliverables, broker collateral treatment and how much settled cash will be available.
Example: a $48 put sold for $2
Suppose XYZ is $50. You sell one standard $48 put for $2 per share, receiving $200, and arrange sufficient cash for a $4,800 assignment payment. If assigned, the economic purchase cost after the premium is $4,800 − $200 = $4,600, or $46 per share, before costs. This is economic trade accounting, not a statement of tax basis.
| Stock price | Outcome | Net profit / loss |
|---|---|---|
| $55 | Put expires unexercised; no shares acquired | +$200 |
| $46 | Buy shares for $4,800; market value $4,600 | $0 |
| $40 | Buy shares for $4,800; market value $4,000 | −$600 |
| $0 | Buy shares for $4,800; shares worthless | −$4,600 |
The maximum gain on the put itself is the $200 premium. Its expiration breakeven is $46, and its maximum loss is $4,600 plus costs. Buying at an effective $46 is not a bargain relative to a market price of $40. If the stock rallies instead, keeping $200 may leave you without the shares you wanted.

Assignment can happen before expiration
American-style puts can be exercised early. The seller cannot defer an assignment until a preferred purchase date or cancel it because the investment thesis changed. Near expiration, holder instructions and broker procedures also matter; a quoted closing price alone is not an absolute promise of assignment or non-assignment.
An executed buy-to-close can remove a still-open short put, but an earlier assignment may already have occurred. Closing can cost more than the premium received. For example, buying this put back at $5 costs $500 and realizes a $300 option loss before costs.
Compare it with a stock limit order
A stock limit order and a short put are different commitments. A limit order seeks a stock fill at an acceptable price and generally can be canceled before execution. A short put remains an option obligation until it is closed, expires or is assigned. Neither guarantees that shares will be acquired merely because the stock touches the desired price.
Before selling, decide whether the position size, cash commitment and potential stock ownership remain acceptable under a severe decline. Use the cash-secured put calculator to compare outcomes, including the possibility of missing a rally.
