Covered Calls, Cash-Secured Puts, and Protective Puts

§ 01Live price and dividend yield for AAPL

§ 02Covered call and protective put compared

§ 03Calculating a covered call's maximum profit

Covered Call: Max Profit = (Strike − Stock Price) + Premium

§ 04When a covered call fits the outlook

Covered calls work best when you expect the stock to trade sideways or rise modestly. If the stock surges past your strike, you miss the upside above it. If it drops significantly, the premium provides only a small cushion.

§ 05Covered call vs protective put by scenario

§ 06Price a covered call on a stock you own

§ 07Total return when the stock is called away

§ 08Covered calls trade upside for income

Covered calls are not free money — they’re a tradeoff between current income and future upside. If you’d be happy selling at the strike price, the strategy makes sense. If you’d be devastated to miss a rally, skip it.

§ 09Upside forgone when the stock runs past strike

§ 10Covered call and cash-secured put equivalence

Covered calls and cash-secured puts are structurally equivalent at the level of payoff math — both have capped upside, both have downside that is bounded only by the underlying going to zero, and both pay the seller a known premium up front. The difference is which side of the position you start on. If you start with stock you would be willing to sell, covered call. If you start with cash you would be willing to deploy at a lower price, cash-secured put. Practitioners often run them together — a covered call on shares of A, a cash-secured put on shares of B that they would rather own at the strike than at today's price.

§ 11The consent test

The consent test. Before either trade, ask: at the strike I am writing, would I be content with what assignment forces me to do? For a covered call: would I genuinely be happy to sell my shares at that price? For a cash-secured put: would I genuinely be happy to buy the stock at that price using the cash I have set aside? If the answer is no in either case, you are not selling income — you are pre-committing to a forced trade you do not actually want. Premium does not redeem an unwanted assignment.

§ 12Assignment risk is real

Assignment risk is real, not theoretical. When the option moves into the money near expiration, the buyer can exercise. Covered-call sellers must deliver shares at the strike whether they want to or not — and in a taxable account that may trigger a long-deferred capital gain. Cash-secured put sellers must buy the shares at the strike whether they want to or not — and that obligation is binding even if the stock has cratered to a fraction of the strike. The cash needs to actually be sitting in the account, not deployed in some other position, on the day assignment lands.
