Is selling options before earning Good Strategy?
It's good until when it's not good anymore. Majority of the time it would be good but once or twice in a while you are going to get losses. And most of the time when you are good, you are going to become more envious of the huge profit that you missed out if you had bought the options or invested in the underlying.
Reel Ken said it well:
We load a six-shooter gun with one deadly round and play Russian Roulette for $100 per trigger squeeze. The odds are 83% (5/6) that you win. Does that make it low-risk? What would low-risk look like? How about a 13-round Glock where your probability of success is over 90%. For certainly, if one defined risk as favorable odds, we would expect many takers, but I'll bet there wouldn't be any.
The reason is simple: One doesn't define risk by the probability of success. I often see this mistake when pundits promote investing strategies such as selling deep-out-of-the-money-puts (DOTM) on volatile stocks and lauding the low-risk-nature of the trade. "The stock would have to drop over x% (6%,7%, 10%) for you to lose". Well, Facebook reminded us of the real risk in such strategies.
Yes, risk isn't the chance of loss, it is the magnitude of potential loss. Too many simply confuse probability with risk.
