Cash-Secured Put vs Covered Call

Quick definitions

• Cash-secured put: you set aside the cash to buy 100 shares and sell a put. You collect premium; if the stock falls to your strike you buy the shares at a discount.
• Covered call: you already own 100 shares and sell a call against them. You collect premium; if the stock rises to your strike your shares are sold (called away).

The surprise: they're nearly the same trade

At the same strike and expiry, a cash-secured put and a covered call have almost identical risk and reward — they're what traders call "synthetically equivalent." Both collect premium, both profit if the stock holds up, and both leave you exposed to the full downside of owning the stock. If that feels surprising, it's because the marketing makes them sound different when the maths says they're twins.

So what actually differs?

• Do you own the shares yet? Covered call = you already hold the stock (and its dividends, and its full downside today). CSP = you hold cash and only buy if assigned.
• Capital flexibility. The CSP keeps your money in cash earning interest until (and unless) you're assigned. The covered call has you fully invested now.
• Dividends. Covered-call sellers collect dividends while they hold; CSP sellers don't, because they don't own the shares yet.
• Direction of the "miss." A CSP that goes wrong leaves you owning a stock that dropped; a covered call that goes "wrong" just means your shares got called away in a rally (you capped your upside).

A simple way to choose

• Don't own it yet and want in at a lower price? Sell the cash-secured put.
• Already own it and want income (and are fine selling higher)? Sell the covered call.

String them together — sell puts, get assigned, sell calls, get called away, repeat — and you've got the Wheel.

The shared risk to respect

Both strategies carry the entire downside of owning the stock. The premium cushions a small drop, not a crash. So the golden rule for both: only do it on a stock you'd genuinely be happy to own, with no hidden earnings or catalyst risk in the window.
