GTW rumor

I read a rumor about how Acer might want to buy GTW (Gateway). I jump in and bought 300 shares when the stock is $1.81 on 8/28. The stock is gradually increase but pretty much stuck when it hits the $1.85 barrier. I was thinking since Acer offered $1.90 per share of GTW, before the deal is finalized, it might not hit anywhere near that price around the end of the year. I'm tired of holding it and I finally sell all 300 shares at $1.86 9/11 which represents 1.47% gain over the course of 2 weeks. Lesson learned here: jump in and follow the herds when you hear about good news such as company's buy-out, but don't forget to still do your own analysis of the company.
