Covered call vs cash-secured put

The short answer

A covered call (own 100 shares, sell a call) and a cash-secured put (hold cash, sell a put) at the same strike and expiry have nearly the same payoff. Both earn a capped premium, and both lose money if the stock falls by more than the premium cushions, so the premium softens a small decline but not a large one.

In theory the two are the same position, and put-call parity is why. In our own replays we measured the put leg directly and have not run a same-strike covered-call comparison, so treat the equivalence as the textbook result, not our finding.

Why they match

Put-call parity ties the two prices together. Owning stock and selling a call gives you the stock's downside and a capped upside. Selling a put gives you the same downside and the same cap on gains. Dividends, early assignment and tax treatment are what separate them in practice.

When you would pick one over the other

Pick the covered call if you already own the shares and want income on them. Pick the cash-secured put if you hold cash and would like to buy the shares at a lower price, getting paid while you wait.

Puts also ask for less attention: if the stock stays above the strike, nothing happens and the put expires. If it falls below, you can be assigned, and American-style options can be assigned early, before expiry, so be ready to own the shares sooner than you planned. Covered calls on shares you want to keep can force a sale you did not plan.

What neither one fixes

Both win often and lose rarely but heavily, so the win rate alone tells you nothing. Judge either on return per dollar of capital tied up, losses included, and compare with simply holding an index fund over the same weeks.
