I purchased CHRS on the recommendation of my broker at a major firm, where he's been for his entire 35 years. He grew my portfolio 68% over the period July '99 through January '02 -- not too bad given the rotton market during this period. He strongly suggested CHRS on the basis of fundamentals and what he has learned from conversations with friends and associates (after 35 years, you get to know people who know people). I'm holding a fairly big position. This guy has rarely been wrong, and when he has, it was evident quickly. In my opinion, this is a winning hold for the near and intermediate term, with minimal downside risk.
