Selling puts is an *extremely* inadvisable strategy!! Why? simply look at the nature of the trade. You are looking at a predefined profit (the premium you receive) and are open to unlimited risk!! As a trader I'm sure that you would agree that the exact opposite is the ideal.... that is unlimited profit potential....with limited risk. Wow!! can't believe that somone would advise that in a book just like that (snap)!! It is possible that the first few trades are winners and lull the trader into believing that there this is easy, just like writing yourself a check. That's exactly when the market will wake you up to the cold reality. I'm not fanatical and realize that shorting/writing puts has its place in a well thought out trading arsenal. However it is NOT to be used by a novice!! An expert trader will always consider the greeks when thinking about selling puts as well as many other considerations.
