Quote from ryanpatrick:
LOL, sorry I had to laugh, because that was my exact point sometime ago too....The question was whether price movement is already priced into the options. From a theoritical point of view, I would have thought so. BUT, from the reality of the trades and experience, I can tell you that only part of the price movement is priced in, especially when the options are due to expired within the week. Time and time again, I've learned that the price was not priced into the options. Which is why I mentioned yesterday about WTW. The only thing that even kept WTW afloat or at -2 to -3 point move instead of -10 points was that share buy back program they announced.
Track those numbers and let me know if market makers have really priced in the total risk of the move on these earning trades. I'd say I would not have made consistent profits if the options priced in the expected swing on these earning trades.
