A naked put is selling a put without the cash to back it. The broker uses your margin to hold the position. You collect premium. Same trade as a cash secured put on paper. Different reality if the stock drops.
Selling naked puts gets sold to retail as easy income. Collect rent on stocks you want to own. What does not get said: when the stock goes to zero, you owe the full strike times one hundred per contract. Margin does not save you. Margin makes it worse.
You sell a put with a strike of $50 on a $55 stock. Premium is $1.50. You collect $150 per contract. The broker holds margin against the position, usually twenty to thirty percent of the notional exposure.
If price stays above $50, the put expires worthless. You keep the $150. If price drops to $40, you owe the difference. You are short the put worth $10 now. You owe $1,000 minus the $150 premium. Net loss: $850.
Cash secured means you have the full $5,000 sitting in your account. Same strike, same risk on paper. But if you get assigned, you have shares at a price you were willing to own. No margin call. No forced sale at the bottom.
Naked puts on margin can trigger a margin call when price drops. The broker sells your other positions to cover. You get liquidated at the worst possible moment.
If any of those bullets are not true, sell cash secured instead.
I sell cash secured puts. Always. Every put I write has the cash to take assignment in my account at the time I open the trade. The premium I collect is smaller relative to the capital. The risk to my account is bounded.
The day I do not have the cash to back a put is the day I do not sell that put.
