$NVIDIA(NVDA.US) closed three small profitable positions the day before yesterday. Before the market closed, I thought about participating in the news-driven move and bought one more share. In the first half of the night yesterday, the stock price plummeted, and I could have taken profits and bought back at the low, but I didn't act. Later, I did some $NVIDIA(NVDA.US). When the news came out, it went from floating profits to huge losses, which was agonizing. Fortunately, the volatility was intense, and there was no one-sided trend. I exited near the secondary high, ending a week of poor positioning. Just recording this.
