A naked option is a short option sold without an offsetting position to cover it — collecting premium but carrying undefined, potentially unlimited risk. It’s the risky end of premium selling.

What it means

“Naked” (or uncovered) means you sold an option with no hedge — no long option capping the risk, no stock backing it. A naked call has theoretically unlimited risk (the underlying can rise forever); a naked put has large risk (down to zero). You collect the premium, but a big adverse move can cost far more than you took in.

Why it's dangerous

Naked options are how undisciplined premium sellers blow up — the short strangle and short straddle are naked structures. They also carry assignment and margin-call risk. Brokers require high approval and margin for them precisely because the risk is unbounded. On 0DTE, a naked position can implode in minutes.

A naked option collects a fixed premium against unlimited risk — the risk shape that ends accounts. The premium is small; the tail is not.

The takeaway

Naked options are uncovered short options with undefined risk — the opposite of defined-risk trading. NoVo trades long options (defined risk, no naked exposure). The safer version of selling premium uses spreads to cap the risk. Understand naked options mainly as a cautionary concept.
