Why is it so easy to make money selling options? What is the catch? I am fairly new to trading options and have much to learn. I did pretty good in Sept by buying calls and puts and selling them when the market hit a turning point. But after reading a bit I discovered that I could sell puts and calls and pocket the premium, making a guaranteed profit if I played it right. Mostly using the last week before expiration. If I am sure where the market is going that week, then it's easy money. If I am not sure, I could sell a spread and let them both decay, closing the one side of the spread before it reaches the strike price. Why is this so easy? Could effectively double my money twice a month if I was a pig (which I'm not). So what's the catch, where's the downside? The only one I can think of is if the market crashes or skyrockets while my head is turned away. ???
