Time decay, or theta, also plays a dual role in this strategy. The short-term call benefits from rapid theta decay, which works in the trader's favor. Conversely, the LEAPS position also loses value over time, though at a much slower rate. The success of the PMCC depends on the "theta spread"—the difference between the daily decay of the short call and the long call. As long as the short call decays faster than the LEAPS, the trader captures a net positive time value.

The primary advantage of this strategy is leverage. Purchasing 100 shares of a high-priced technology stock like NVIDIA or Microsoft can require tens of thousands of dollars in capital. A LEAPS contract, however, might cost only 20% to 30% of the price of the actual shares while providing nearly identical exposure to upward price movements. This increased capital efficiency significantly boosts the potential return on capital (ROC). If the underlying stock remains stable or rises modestly, the monthly income from selling covered calls can eventually pay for the entire cost of the LEAPS, leaving the investor with a "free" long-term bullish bet.

However, the PMCC is not without unique risks, most notably the "upside gap" risk. In a traditional covered call, if the stock price skyrockets past the short strike, the investor simply sells their shares at a profit. In a PMCC, if the stock price rises too quickly, the short call may become deeply ITM while the LEAPS has not gained enough value to cover the obligation, especially if the spread was set up with a narrow width between the long and short strikes. To mitigate this, traders must ensure that the total debit paid for the spread is less than the distance between the two strike prices. If the stock price exceeds the short strike, the trader may be forced to close the entire position for a loss or a smaller-than-expected profit.
