NEW YORK - Shares of biotechnology companies traded mixed Tuesday as the broader market wobbled after consumer confidence data came in below expectations, UPS issued a profit warning and oil prices continued to rise, while the Federal Reserve began rate-setting meeting.
In industry news, R.W. Baird analyst Thomas Russo increased his price target for Gilead Sciences Inc. stock to $53 from $52, and raised his profit and revenue estimate, while trimming his estimates for Amylin Pharmaceuticals Inc.
Here's how several key biotechnology stocks performed Tuesday:
Gilead Sciences slipped 25 cents 54.52.
Amgen Inc. added 75 cents to $46.64.
Biogen Idec Inc. gained 6 cents to $56.59
Genentech Inc. gave up 76 cents to $73.42.
(This version corrects an earlier version that included Cubist Pharmaceuticals Inc. among the stocks for which Russo changed estimates.)
