Stephen Chin  UBS

The buy side says: “He is an important resource to better understand the constantly changing landscape.”

Stephen Chin of UBS jumps two notches to seize his first No. 1. A “hard worker” who is “constantly in touch with all the news flow in the solar space,” as one money manager puts it, Chin upgraded GT Advanced Technologies from neutral to buy in August 2010, at $7.81, convinced that the Merrimack, New ­Hampshire–based company’s new LED-­equipment business would spur order growth. In early August, GT announced that it had booked nearly $1 billion in LED-­equipment orders. The stock had lit up a gain of 56.3 percent, to $12.21, and overshadowed the Standard & Poor’s global clean energy index by 77.6 percentage points, by the end of that month. Chin, 40, joined UBS in 1999 after earning an MBA at Cornell University’s S.C. Johnson Graduate School of ­Management.
