[Smile] //@Kelvinphan:Go//@daz888888888:$Rigel Pharmaceuticals(RIGL)$  Insiders who bought Rigel Pharmaceuticals, Inc. (NASDAQ:RIGL) stock in the last 12 months were richly rewarded last week. The company's market value increased by US$14m as a result of the stock's 11% gain over the same period. As a result, the stock they originally bought for US$688k is now worth US$834k. While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, we would consider it foolish to ignore insider transactions altogether.
