4) the price of a stock's probability distribution is based on a normal curve. The more likely shape should be a fat-tailed curve ergo..."The Black–Scholes model of option pricing is based on a normal distribution. If the distribution is actually a fat-tailed one, then the model will under-price options that are far out of the money, since a 5- or 7-sigma event is much more likely than the normal distribution would predict." AND "...
"1. The Black-Scholes model overprices “at the money” call options, that is
S≈K The Black-Scholes model underprices call options at the ends, either deep “in the money”,
S>>K , or deep “out of the money”, S<<K ."

Sell at the money call options and buy them at the margins.
