My biggest complaint on covered calls is that they don't behave well for large, abrupt moves in share price, either up or down. If the stock moves smoothly in either direction, the CC behaves pretty well.
Here's a few poor man's covered call examples that I've traded recently. The orange curve is the price of the LEAP option (the long leg of the PMCC). My LEAP was typically 90-180 DTE, 80+ delta, while my short calls were typically 10-20 DTE, 30 delta. I rolled the short calls out when their value fell by > 50% or if the value more than doubled.
DISH (Dish Network). Huge, quick upside move. I was able to capture about half that upside. Then there was a quick move to the downside. The PMCC didn't cushion me at all.
INTC. Large upside move before Q1 2021 earnings, which I failed to capture. After earnings, INTC made a huge move down, and I essentially took max loss. PMCC failed as a hedge. You can see how I was slowly digging out of the hole from May to July, but still -40% on the LEAP. (The PMCC has a lot of leverage!)
TLT. This one worked pretty well, since the movements of the share price were less abrupt. The PMCC cushioned the moves down. In exchange, it gives up some of the upside.
I am still using the PMCC, but I've given up on individual shares. Broad ETFs tend to have less risk of abrupt moves up or down. I mainly use the PMCC as a delta management tool. I will use RSI at trade entry to tweak the delta of the short calls, but default is to sell ATM calls.
Anyway, I hope some concrete examples are of use to the OP. Critical feedback invited.
