buying the volatility before earnings.. and scalping the price action.. price action volatility doesn't have to be very high to cover the carry difference between entrance and exit before earnings.. you could make it just on the vol increase.. but thats good you have to tides going your way.. potential implied increase and then potential to scalp pre earnings price action.. am i getting that right?
fwiw - i did the ebay on your recommendation. i saw the same thing you did. i made a little bit of money (about 5% on teh straddle premium) but I didn't hedge the turns well and so left a lot of gamma pnl on the table.
