the NVIDIA (NVDA) trade

NVIDIA is a great company, but a tough stock to trade. Most recently I was able to ride some shares from the 8$ range to the 30$ area. The stock began to show signs of weakening (as was the market) so I took profit. I recently bought some shares back for about 21$. It is a small position, maybe early, but the MACD indicator just went positive. NVIDIA makes graphic chips for computers, video games and cell phones. They dominate the space and have eliminated most of their competition.
