Yes, it does. Was trying to buy some ISRG puts a little cheaper this morning and noticed they started taking it higher, so pulled my order and went to lunch. My puts would have filled at $11.20 and are now bidding $30.40. Even more spectacular were the Mar $510, trading as low as $1.59 when they took ISRG higher and later as high as $26 in a couple hours or so. First AAPL, then ISRG, and now AMZN is down $10 on a strong day in the market. Are the pros starting to take apart the pricey big gainers one by one? Is AMZN next? NFLX?
