I realize this is nothing new but I'm wondering if, as a rule, the following method of trading is successful. I've noticed that, while watching CNBC at 8:30CT on the open, Maria B. will typically say some larger NYSE stocks haven't yet opened for trading but are indicated lower. Is it a good idea to buy here with the specialist at the open, when stock has gapped down and specialist has bought the shares at a bargain, then sell 15-30 minutes later after the specialist has moved the price higher. This seems to happens all the time. Friday was a classic example - just look at IBM and KR. Thanks, guys!
