Stock Repair Calculator

By Dennis Bosmans · Updated June 2026 · 2 min read · Risk disclaimer

The stock repair strategy adds a 1×2 call ratio spread to a losing long position — buy one at-the-money call and sell two out-of-the-money calls, usually for near-zero cost. It doubles your recovery between the current price and the short strike, lowering your effective breakeven without adding capital.

Key characteristics

When to use stock repair

Use it when a stock you own has fallen and you expect a partial rebound — enough to get back toward your cost, but not a full moon-shot. The extra long call doubles your participation in a bounce up to the short strike, lowering the price at which you break even.

Because the two short calls usually pay for the one long call, it costs little or nothing and adds no new downside: if the stock keeps falling you are no worse off than simply holding the shares.

Risks and management

The trade-off is a capped upside. Above the short strike the two short calls offset the extra gains, so a powerful rally past that level is the "good problem" — you recover fully but give up the runaway upside.

It does not fix the original downside: you still own the stock and lose if it keeps falling. Choose the short strike around your target rebound, and remember it is a repair, not a way to add risk.

Worked example. You own 100 shares bought at $100, now trading at $90. You buy the $90 call and sell two $100 calls for about zero net cost. If the stock recovers to $100, the extra call roughly doubles your gain over that range, getting you back to breakeven near $90 instead of needing the full move back to $100. Above $100 your gains are capped.

Key takeaways

Frequently asked questions

Does stock repair cost anything?

Usually very little. The two out-of-the-money calls you sell typically pay for the one at-the-money call you buy, so the add-on is close to zero cost.

Does it add downside risk?

No. If the stock keeps falling you are in the same place as just holding the shares — the ratio spread expires worthless and you lose nothing extra on it.

What happens if the stock soars?

Your gains are capped at the short strike, because the two short calls offset the extra upside. You still recover fully; you just do not benefit from a runaway rally.
