A cash-secured put is selling a put option while setting aside enough cash to buy the 100 shares if you're assigned. You collect the premium upfront. If the stock stays above the strike, the put expires worthless and you keep the premium; if it drops below, you buy the shares at the strike (minus the premium you collected).

"Getting paid to set a limit order"

The appeal: if you wanted to buy the stock at a lower price anyway, selling a put at that strike pays you a premium to wait. If assigned, you get the shares at a price you liked, effectively discounted by the premium. If not, you keep the premium as income. It's a limit order that pays you to sit.

The real risk

The catch is what happens in a crash. If the stock plunges well below your strike, you're obligated to buy at the strike — far above the new market price. The premium is a thin cushion against a large loss. Your max loss is nearly the full value of the position (strike minus premium, if the stock goes to zero) — the same downside as owning the stock, minus the premium.

A cash-secured put is bullish. In a real selloff, "getting paid to buy the dip" becomes "obligated to catch the knife."

Where it fits

It suits a genuine willingness to own the stock at the strike, with the cash truly set aside — not as "free money." Like covered calls, it's a premium-selling strategy where time decay works for you and your upside is capped at the premium. Respect the assignment obligation before the yield tempts you.
