Covered call vs cash-secured put: same risk, two doors

One starts with shares you own. The other starts with cash you set aside. They feel different, but their risk pictures look almost the same. Here's why.

The short answer

A covered call means you own 100 shares and sell a call option on them. You collect a premium. In return, you agree to sell your shares at the Strike price if the buyer exercises. See Covered call.

A cash-secured put means you set aside enough cash to buy 100 shares and sell a put option. You collect a premium. In return, you agree to buy the shares at the strike if the buyer exercises.

Both collect a premium. Both cap your upside. Both still carry the full downside of owning the stock, minus the premium.

Side by side

How a covered call works

A math example. You own 100 shares bought at $50. You sell a call with a $55 strike for $1.00 a share, so $100 total.

• Stock stays under $55: the call expires. You keep the $100 and the shares.
• Stock rises to $60: your shares get called away at $55. You gain $5 a share plus $1 premium, $600. You miss the move above $55.
• Stock falls to $40: you keep the $100 premium, but your shares lost $1,000. Net loss: $900.

A math example, not a promise. Real results include commissions and depend on timing.

How a cash-secured put works

A math example. A stock trades at $52. You set aside $5,000 and sell a put with a $50 strike for $1.00 a share, $100 total.

• Stock stays above $50: the put expires. You keep the $100.
• Stock falls to $40: you're assigned and buy 100 shares at $50. You're down $10 a share, minus the $1 premium. Net loss so far: $900.

A math example, not a promise. See Assignment for how that works.

Why they look so alike

Look at the two "falls to $40" lines. Both lose $900.

That's not an accident. Option math links calls, puts and shares. A covered call and a cash-secured put at the same strike and date have very similar payoff shapes. Both:

• collect a small, capped premium
• give up big upside
• keep most of the downside

The difference is mostly where you start: shares or cash.

Covered call: strengths and limits

• Fits if you already own shares and would be fine selling at the strike
• Premium cushions small drops
• Caps your upside; a big rally passes you by
• Can tempt you to hold a falling stock "for the premium"

Cash-secured put: strengths and limits

• Fits if you'd be fine buying the stock at the strike
• Cash must sit idle as collateral
• If the stock crashes, you buy it at the strike anyway
• Needs options approval at your broker

Which fits you?

• Already own 100 shares and okay selling higher? A covered call matches that.
• Want to own a stock, but only at a lower price? A cash-secured put matches that.
• Not sure you'd want to own the stock at all? Then neither fits. Both leave you holding the stock when it falls.

Pick stocks you'd hold through a drop. And size the whole position, not just the premium, with your risk rules. See options trading basics.

Common mistakes

• Calling the premium "safe money." The stock risk is still there.
• Selling puts on stocks you'd never want to own. Assignment happens.
• Chasing the highest premium. High premiums usually mean higher expected swings.
• Forgetting earnings dates. A big earnings move can blow through either strike.
