Comparison
Covered call vs cash-secured put
These are the two strategies most investors meet first when they move from buying options to selling them. A covered call sells someone the right to take shares you already own at a strike price, collecting a premium. A cash-secured put sells someone the right to sell YOU shares at a strike, with cash set aside to honour it. Different starting points — one begins with shares, the other with cash — yet their payoff shapes are nearly mirror images.
| Covered call | Cash-secured put | |
|---|---|---|
| You start with | 100 shares per contract | Cash to buy 100 shares at the strike |
| You sell | A call against your shares | A put against your cash |
| Premium compensates for | Capping your upside above the strike | Committing to buy if price falls below the strike |
| If price rises sharply | Shares called away — profit capped | Put expires; you keep the premium, but hold no shares |
| If price falls sharply | You still hold the shares (premium cushions) | You buy at the strike — above the new market price |
| Educational nickname | Renting out your shares | Getting paid to name your buy price |
Why the payoffs mirror each other
Put-call parity again: owning shares plus a short call produces the same expiry payoff shape as holding cash plus a short put at the same strike. Both cap the best case at 'strike plus premium' and both wear the downside of ownership below the strike. The practical differences live in the details — dividends accrue to the covered-call writer who holds shares, while the put writer's cash may earn interest until assignment.
The risk people underestimate
Neither strategy is 'free income'. The covered call's real cost shows up in the strong rally you gave away; the cash-secured put's shows up in the sharp fall, where you are obliged to buy at a strike the market has left behind. Both are equivalent to being paid today for accepting a defined obligation tomorrow — the premium is compensation, not a bonus. Our Options Lab lets you replay both structures on real charts to see those trade-offs resolve.
Frequently asked questions
Which earns more premium?
At the same strike and expiry, the call and put premiums are linked by parity and generally similar once dividends and interest are accounted for. Neither is systematically 'better paid' — the market prices the mirror obligations consistently.
What is the wheel strategy?
A rotation between the two: sell cash-secured puts until assigned shares, then sell covered calls on those shares until they're called away, and repeat. It chains the two obligations end to end — with the same capped-upside, full-downside trade-offs at every step.
Are these strategies safe?
They are defined-obligation strategies, not low-risk ones. Both carry substantially the downside of share ownership. 'Covered' and 'secured' describe how the obligation is collateralised — not the absence of risk.
