Selling covered calls against LEAPs, long-term options is a strategy very similar to traditional covered call writing. However, the way I use them in my account is very different from what other covered call writers do. I approach selling calls against LEAPs on low-volatility or minimum-volatility stocks with splendid momentum and fundamentals as a bullish strategy. For those of you familiar with the strategy, the math can still be challenging. That's why I've developed a calculator which will do the leg work for us: what is the return on the option, what do we have to do if the short call its in-the-money at expiration?
