Covered Ratio Spread Options Strategy
Learn the covered ratio spread with stock, two lower-strike short calls and one higher long call, including its profit peak, upside plateau, downside, and assignment.

Direct answer
A covered ratio spread commonly owns 100 shares, sells two calls at a lower strike, and buys one call at a higher strike, with all options sharing an expiration. One short call is covered by the shares; the second lower-strike short call and higher-strike long call form a bear call spread. Maximum expiration profit usually occurs at the lower call strike. Between the call strikes, profit declines as the second short call loses faster than the stock gains; above the long-call strike, the payoff reaches a lower plateau. The structure avoids unlimited upside loss when quantities match, but it caps stock appreciation and retains substantial downside if the shares collapse.
The shares and call spread create three regions
Below lower strike K1, all calls can expire worthless and the position behaves like long stock plus the opening option credit or debit. At K1, the shares reach the strategy's usual profit peak.
Between K1 and higher strike K2, two short calls work against one stock unit, so net exposure turns negative. Above K2, the higher long call restores a flat net slope.
Covered does not mean every leg is riskless
The stock delivers shares for one short call. The second short K1 call is paired with the long K2 call, creating a defined-width call credit spread rather than another covered call.
The whole position can avoid an uncovered upside tail, but it still has spread loss between K1 and K2, early-assignment mechanics, and nearly full stock loss toward zero.
Profit peak and upper plateau are different
At K1, maximum profit is commonly K1 minus stock purchase price plus net option credit, before fees. As price rises toward K2, the extra short-call intrinsic loss reduces that amount.
Above K2, the options and shares offset into a fixed expiration result. Calculate that plateau explicitly; it may be much less attractive than simply selling one covered call.
Downside resembles stock ownership
If the stock drops below both call strikes, the options may expire worthless and only their net cash flow cushions the share loss. No put floor is present.
Stress a zero-price stock, dividend changes, volatility expansion, and a widened multi-leg market. More option premium does not convert long-stock downside into defined risk.
Assignment changes the decomposition
One or both lower-strike American calls may be assigned early, especially around dividends. Assignment can remove shares or create a temporary short-stock position while the higher call remains open.
Plan how to close all option legs, whether to sell shares, and whether exercising the long call would destroy time value. Do not confuse this short-low, long-high call arrangement with the opposite call placement used in stock repair.
Common questions
Is every short call in a covered ratio spread covered by stock?
No. The shares cover one; the other is paired with the higher long call as a defined-width call spread.
Where is maximum profit?
Usually at the lower strike of the two short calls at expiration, adjusted by stock basis, option cash flow, and costs.
Can the strategy lose if the stock rises?
Profit can decline between the short- and long-call strikes, even though the stock rises, because two short calls oppose one share lot.
Is covered ratio spread the same as stock repair?
No. The common covered ratio sells two lower calls and buys one higher call; stock repair buys one lower call and sells two higher calls.
