Stephen Chin UBS
Although he slips from second place to third, Stephen Chin of UBS maintains a loyal following, thanks to his “deep understanding of the semiconductor capital equipment, solar and [light-emitting diode] spaces,” in the words of one money manager. Last October, Chin upgraded Rubicon Technology of Franklin Park, Illinois, from neutral to buy, at $17.01, after learning that the company was building a new factory to double its output capacity. The stock had surged 44.1 percent, to $24.51, by late August.
