Naked Options
Selling options without a hedge — undefined risk positions.
A naked option (also called an uncovered or undefined-risk option) is a short option position where the seller does not hold a corresponding position in the underlying stock or an offsetting option to limit risk. Selling a naked call means you have no shares to deliver if assigned. Selling a naked put means you have no hedge if the stock drops to zero. The theoretical risk on a naked call is unlimited.
Why It Matters
Naked options offer the highest premium collection of any single-leg options strategy because the seller takes on the most risk. Many professional traders and market makers regularly sell naked options, but they manage the risk through position sizing, portfolio diversification, and active management. For retail traders, naked options require the highest approval level (usually Level 4 or 5) and a margin account.
The allure is real — naked options have a high win rate because you collect premium and keep it if the stock stays within a wide range. But the losses when they come can be severe and fast. Understanding the mechanics is critical before stepping into this territory.
How It Works
Naked calls: You sell a call without owning the underlying stock. If the stock rallies past your strike, you must buy shares at the market price to deliver at the strike — or close the position at a loss. Since a stock can theoretically rise without limit, the potential loss is unlimited.
Naked puts: You sell a put without a corresponding short stock position or offsetting option. If the stock drops, you must buy shares at the strike price regardless of how far the stock has fallen. Maximum loss occurs if the stock goes to zero: strike price times 100, minus the premium received.
Margin requirements for naked options: Brokers use formulas to calculate the collateral required. A common Reg T formula for naked options is:
20% of underlying price - OTM amount + option premium (per share)
For a $100 stock, a naked $95 put trading at $2.00 might require: (20% x $100) - $5.00 + $2.00 = $17.00 per share, or $1,700 per contract.
Risk management for naked options:
- Set a stop-loss or buy-back rule (many traders close at 200% of the premium received)
- Keep position sizes small relative to your account
- Diversify across uncorrelated underlyings
- Maintain at least 50% of your buying power as a reserve
- Be prepared to manage positions actively
When naked options make sense:
- On stocks you would be comfortable owning (for puts)
- When IV is elevated and premiums are rich
- When you have sufficient buying power to absorb adverse moves
- As part of a diversified, actively managed portfolio
Quick Example
You sell a naked $90 put on a $100 stock for $1.80, collecting $180. Your buying power is reduced by roughly $1,600. If the stock stays above $90, you keep the full $180 — a return of about 11% on capital used.
If the stock drops to $75, your put is $15 in the money. Your loss is $15.00 - $1.80 = $13.20 per share, or $1,320 per contract. If the stock gaps down to $50 overnight on bad news, your loss is $38.20 per share, or $3,820 per contract — far exceeding the premium collected.
