Quote from optioncoach:
Covered straddle at $16.15, I just wanted to profit from the IV drop, from 54% to 41% in NOV straddles.
Great example of knowing how volatility works. Stock gapped from 174 to 187 and the 175 straddle went from 19.30 to 16.15 when I covered at 9:41 AM. VOl crush.
People who bought the straddle expecting a big move, got the move but still lost money, purely on volatility.
There are always people on the Yahoo boards saying things like "I bought the calls and it moved up, but I still lost money. How can that happen?"
