Efficient Market, from Rocky Humbert
TSLA is down $26 (about 15%) today post-earnings. That seems like a pretty big move. But it isn't.The stock was trading at about 170ish yesterday. If I had bought the at-the-money straddle (170 calls and 170 puts) expecting a "big" move, I would have broken even. The Chair, who would have sold the 170 calls and the 170 puts, would also have broken even. The Chair won this round.
