Naked Put
A short put option without holding the full cash to cover potential assignment, using margin instead and creating undefined downside risk.

What Is a Naked Put?
A naked put is a short put position opened without holding sufficient cash to cover the full purchase of shares if assignment occurs. The seller collects premium upfront in exchange for the obligation to buy 100 shares at the put’s strike price if the buyer exercises. Unlike a cash-secured put—where the full cost of potential share purchase is held in reserve—a naked put uses margin to back the position, allowing the trader to control more risk relative to their account equity.
The “naked” designation refers to the absence of a hedge. There is no long put to cap downside losses, no long stock position to offset adverse moves. If the underlying collapses dramatically, losses can approach the full strike price multiplied by 100 shares, minus the premium received—theoretically substantial, though maximum loss is capped at the strike price minus premium if the stock goes to zero.
Many traders view naked puts on stocks they’d own as disciplined income generation—if assigned, they acquire shares below current market at an effective discount.
Example structure (stock at $100):
- Sell the $90 put for $1.50 ($150 premium per contract)
- Maximum profit: $150 (underlying stays above $90 at expiration)
- Breakeven: $88.50 (strike minus premium)
- Maximum loss: $8,850 (underlying goes to zero; strike of $90 minus $1.50 premium, times 100 shares)
Why It Matters for Options Traders
Naked puts are one of the highest-leverage premium-selling strategies available. Because the full cash to cover assignment is not required, the margin requirement is typically a fraction of the notional value—allowing traders to collect premium across multiple positions simultaneously.
The strategy is mechanically bullish: the seller profits when the underlying stays flat, rises, or declines only modestly. Many experienced traders view selling naked puts on stocks they would own as a disciplined income approach—if assigned, they acquire shares at an effective price below the current market (strike minus premium). This perspective aligns with a willingness to hold the underlying and is a key consideration before entering any naked put position.
The practical distinction from a cash-secured put is the margin treatment and the regulatory context. Brokers require approval for naked puts (typically Level 3 or higher options approval), and the position appears riskier on paper because it is not fully cash-backed. In elevated IV environments, the premium collected from a naked put can be significantly larger than from a spread, which is why some traders accept the undefined risk in exchange for the higher credit.
Key Characteristics
- Undefined downside risk: Maximum loss equals (strike price minus premium received) times 100 shares if the underlying goes to zero
- Maximum profit: The premium collected—realized when the underlying closes above the short put strike at expiration
- Breakeven: Short put strike minus premium received
- Margin requirement: Typically 15-20% of the stock price times 100 shares, plus premium, minus out-of-the-money amount
- Assignment risk: If the underlying closes below the strike at expiration, the seller must purchase 100 shares at the strike price
- Same risk as cash-secured put: Difference is capital allocation—naked put uses margin instead of reserved cash
- Requires elevated broker approval: Typically Level 3 or higher options trading authorization
- Ideal environment: Elevated IV with a bullish or neutral outlook on a stock the trader would be willing to own at the strike price
