mark this is untrue. Your statement is implying risk premium is overpriced and besides that, the market is 100% efficient. There are quite a few rocks to turn over if you are managing under 500k in the options market.what do you hope to gain by trading options in the first place? selling is for deep pockets and ice water, not blood in your veins and buying for fools who believe it's safer. mix the two and your wasting time making nothing, but the clearing firm will profit for sure. this is exactly why clearing firms promote this style of trading it bleeds your money slowly so they can get the maximum commissions out of you in the process.
+ risk premium on certain assets is not always over priced. I would also mention a butterfly is short vol and is pretty easy on margin. So if your theory is correct (risk premium is always overpriced), why could you not trade butterfly's for a profit?
