If SAP said they would Pay $15 would Price goto $7 maybe?
Exactly. You want to buy on big volume down days (like yesterday, which I did) and sell on big volume up days. You might sell a little early (like I did at a little above $8 before it climbed to nine) or buy a little late. But to do the opposite, buy at nine or in the high eights when there is uber excitement and then panic or get a major depression when it drops is ridiculous and the mark of an amateur. If you want to buy and hold, I would advise 1. not investing anything you cant lose (which should be for any investment) and 2. cost average in and 3. dont check the quote daily, maybe once a week instead.
