I work at AMD. I have for a long time. The fortune I've left on the table makes me sick. 20-30% swings in 2 weeks was a way of life for years and years. I've certainly made out pretty well in the past 2 years, selling years of stock grants at $30, $40, $50, and earlier this week sold at $80. But about 4 years ago, when the stock was still in the $2.50 range, I was ready to pull the trigger on 20k shares in my own personal investment account. I talked myself out of it because I know our internal roadmaps and I knew about a pretty major announcement that was going to be made that I knew would make the stock jump quickly. Even though my plan was for a long-term play due to what I knew was finally going to be a successful product lineup, my conscience told me it wasn't ok. The only thing that allows me to sleep at night is the knowledge that I probably would have sold those shares when they with $10 anyway.
