I have dabbled in covered calls and it isn’t a fast, easy way to get rich. No way you could get 2-4% per month on a consistent basis. Just go back and look at what option contracts stood at on days where the market really skyrocketed.
Now the only time I place covered calls is if I have a stock I am planning on selling but I’m not in a hurry to sell and and want to see if I can make a couple extra dollars.
