Naked Call

Sell a call without owning the stock. High risk — unlimited loss potential if the stock surges.

What is a Naked Call?

You sell a call without holding the underlying shares. You collect premium, but if the stock rises above the strike, you must deliver shares at that price (buying them at market). Since stocks can rise indefinitely, your loss is theoretically unlimited. This is the highest-risk option strategy and requires significant margin.

When to use it

Only used by experienced traders in very bearish or low-volatility environments. Not recommended for most traders due to unlimited risk. If you must sell a call naked, use a stop-loss or be prepared to roll aggressively.

Structure

Sell 1 call without owning 100 shares of the underlying.
