What is a cash-secured put?

The foundational strategy behind most of what Collect52 covers — here's how it actually works, in plain terms.

The basic idea

A cash-secured put is an agreement where you get paid upfront (called the "premium") in exchange for agreeing to buy 100 shares of a stock at a specific price (the "strike price") if the stock falls to or below that price by a certain date (the "expiration date"). You set aside the cash needed to buy those shares if that happens — which is what makes it "cash-secured."

A concrete example

Say a stock is trading at $52. You sell a put with a $50 strike expiring in 30 days, and collect $120 in premium upfront. Two things can happen: if the stock stays above $50, the option expires worthless, and you keep the $120 — full stop. If the stock falls below $50, you buy 100 shares at $50 (your cash was already set aside), but your true cost is $50 minus the $1.20/share premium — effectively $48.80 per share.

Why people do this

It's a way to earn income from cash sitting in your account, or to potentially buy a stock you'd be happy to own anyway — at a discount, since the premium lowers your effective purchase price. It's generally considered a more conservative options strategy since your worst case is owning a stock at a price you already agreed to.

The real risk

If the stock drops well below your strike price, you're still obligated to buy at the strike — meaning you could end up owning shares worth significantly less than what you paid, even after the premium cushion. This is why the underlying stock still matters — a cash-secured put isn't a way to avoid stock risk, it changes the shape of it.
