No. If you weren't in the stock for the big pop or sold when that happened, you simply have to 'say you missed this one' and wait for the stock to either settle down or fall off enough for you to put money in. I wouldn't buy above 650 in this new 'range'. You simply will be in too great of a risk of getting gamed by the momentum players.
Short term rating = HOLD
Long term rating = BUY
