hi Mike - i have recently run some numbers on historical volatilities for the stocks in the Russell 1000 - even if you take the relatively lower volatility environment from 2003 to present, the "fat tails" are still significant, from memory my numbers showed the frequency of 3+ standard deviation events to be on average 3 times greater than under the standard normal distribution (2+ std dev. higher also) - the biggest option sellers, e.g. market makers, are compensated for this by the typically higher implied volatility than historical volatility, in addition, they must be highly diversified among the stocks so that if they take a hit or several, this still will be a small portion of their portfolio, also i presume they use overall portfolio insurance against market-wide events - in the end, i couldn't justify picking a relatively small number of stocks and selling options on them, from my numbers, without a high level of diversification, i'd end up taking more hits than necessary to make profits... - i wanted to see what your take on this is and whether you have looked at the historical data - in either case, base of luck with your trading.
