Dont quite understand why NVDA has been climbing steadily only to drop drastically toward the close of the day. However, for me my strategy is to pick up the shares each time it drops to a new low for the day and hold till it reverses the next session. It jas been going well for me so far. I love the roller-coaster rides. The momentum creates good profits for me. Perhaps I was lucky? Indeed for such trades I do take risks but then I have the holding power for NVDA.
