Biotech had a very positive week. Over the four sessions, the Centient Biotech 200™ rose 116 points to 3995, a 3% climb. That puts biotech back in the black for 2007, with a gain of 1.8% since the first of the year. Of particular satisfaction is that biotech did much better than broad market averages, something that has not happened very often lately. The S&P was up only 1.6% and Nasdaq ended the week with a 2% rise. >>> Discuss This Story
