The sun has been shining on the biopharmaceutical sector of late as investors have returned to the sector big time. As a result, the BioWorld Biopharmaceutical index grew a healthy 6.6 percent in the second quarter, well ahead of the general markets, thanks to a late June spurt in valuations, causing the index to grow 5.8 percent last month. In contrast, the Nasdaq Composite index lost almost 1 percent in value in June and closed the quarter up 3.9 percent, and the Dow Jones Industrial Average eked out a 1.6 percent jump in value for the month and was up 3.3 percent for the quarter.
