Selling at $8.14 even today. You just lost 2% in 5 minutes. That is what you could have made at a bank in a CD if you kept it there 3 years! If you waited 10 days you may have gotten 5% more with the buyback. Time is money and you lost a lot of money in a short amount of time. Too funny.
There are many reasons for SELLING a stock: divorce, job loss, foreclosure, and most common the belief that another opportunity presents a greater appreciation, or just a swing trader taking profits. They say that you never lose money taking a profit, and some would even say that was very SMART. You may not be personally aware of a better opportunity or place for your money, or you may not agree with their assessment, but that doesn't mean they are "stupid".
There is only one reason I can think of for BUYING a stock - because you believe it has a good chance of appreciating.
