With regard to Betapeg and his trading: I can say that it is possible to make money by selling otm options, but the numbers that most people use are always wrong. You cannot make 50% per year as is claimed here and only have a 1-2% drawdown. In the long run you may be able to make 20 or 30% but you will have a 50% drawdown. If you happen to retire before the infrequent but inevitable giant gap move, then that is just luck not skill.
The position screen shot that was posted had 10 CL, 30 NG, 10 ZC, 10 ZS, and 10 ZW. I would give credit for diversification but there are only two groups represented here. I believe it was posted that to be short these options one only need $100,000 in their account. Herein lies the problem, and why people who do attempt this strategy do not sell so far out of the money. You need way more capital than that, thus the return is nowhere near 5% per month. If you were crazy aggressive you would need $300k, and to be just normally aggressive you would need $600k to hold these positions. Taking in $5k on a $100k account seems great, but use a more realistic number of a $500k account and all the sudden the return is nothing to get excited about, unless making 1% in about two months while at the same time being subject to at least a 50% drawdown gets you excited.
Everyone who takes home a position in an underlying has the same as naked option exposure risk, so the vast majority of the world is naked short puts and the short sellers are naked short calls. The main problem is not with being naked short, the main problem is one of leverage and therefore your actual risk vs. return ratio.
