I've been a trader and investor for a long time. I've been through numerous stock splits in various stocks. Stock splits introduce some trading distortions, or noise if you prefer, on both sides of the actual split date. You have to let the dust settle from the split and the action returns to fundamentals. Nvidia went up in price robustly on big down day and today down somewhat in an up market. Such is the nature of markets.$NVIDIA Corp(NVDA)$
