While at Fidelity, he managed the Fidelity Select Pharmaceuticals Portfolio fund which was rated by Lipper in 2013 as the number-one global health/biotechnology fund based on his three- and five-year performance. He also served as Fidelity’s senior analyst covering global pharmaceutical companies. Andy previously held similar roles at JP Morgan and Stifel Financial.
