Annualized Yield Is a Comparison Tool, Not a Forecast

What the calculation does

Annualizing a period return is simple arithmetic: take the yield earned over the option's holding period and scale it up as if that same yield repeated for a full year. A put that returns 1% of collateral over 7 days annualizes to roughly 1% times (365 divided by 7), or about 52%. The formula makes no claims about what will actually happen for the next 358 days — it's a unit conversion, turning a short-period return into an annual-equivalent rate purely for comparison purposes.

The reason this conversion exists at all is that a 1% return over 7 days and a 4% return over 45 days aren't directly comparable as raw percentages. Annualizing puts them on the same time basis: roughly 52% and roughly 32% respectively, which makes clear the shorter-dated trade is offering a better rate of return per unit of time, at least on paper.

Why the number inflates for short-dated trades

Because the scaling factor is 365 divided by the holding period, the annualized number grows purely mechanically as the holding period shrinks — even if the underlying risk and effort scale up right alongside it. A 0.5% yield over 3 days annualizes to over 60%, not because the trade is unusually good, but because dividing by 3 does that to any number. Very short-dated options routinely produce eye-catching annualized figures for this mechanical reason alone.

It also assumes you can repeat the exact same trade, at the exact same yield, every single period for a full year, with zero downtime, zero losing trades, and zero compounding friction. In practice, some weeks the premium available at your target delta is thinner, some weeks you're assigned and rotating into a covered call instead of a fresh put, and any losing trade — a stock gapping down through your put strike — erases many weeks of collected premium at once. None of that shows up in the annualized figure for a single trade.

What to actually do with the number

Use it to compare trades against each other on a level time basis, not to forecast an achievable annual return. A put annualizing to 40% and a put annualizing to 25% on similar-quality underlyings tells you the first is being compensated at a better rate for the time and capital involved — that comparison is legitimate. Neither number is a prediction that your account will be up 40% or 25% a year from now.

Weigh a high annualized yield against why it's high. Elevated implied volatility drives up premium and, with it, the annualized figure — often for a reason, like an approaching earnings report, that also raises the odds of a large adverse move. A conspicuously high annualized number on an otherwise ordinary stock is worth a second look at the calendar before it's worth celebrating.
