From TheStreet:
The biotech sector has been one of the best performing sectors this year. While the Nasdaq Composite rose 5.3% for the first six months of the year, the Nasdaq Biotech Index rose a whopping 21.6% as of June 30. In comparison the S&P 500 Index barely eked out a positive return for the first two quarters.
Even within the red-hot biotech sector, there are superior performers. Here they are.
