Kunihiro Matsumoto UBS

The buy side says: “He is capable and insightful.”

Kunihiro Matsumoto of UBS claims the top spot for a fifth straight year. Praised by one client for his “good investment ideas,” the 46-year-old follows 23 companies; that figure is unchanged from last year, and ­Matsumoto does not foresee adding to his universe. Winning recommendations of late include an upgrade on ­Calsonic Kansei Corp. from neutral to buy in February 2011, at ¥359, largely on growing demand from parent ­Nissan Motor Co. Calsonic’s shares plummeted to ¥278 two months later, following the Tohoku earthquake and tsunami, but ­Matsumoto pounded the table, arguing that the Saitama-­based supplier of radiators, mufflers, car alarms and other components would rebound quickly. He was right — and by the end of February, the stock had surged 30.6 percent, to ¥469, since his upgrade. In ­October, ­Matsumoto cut Exedy Corp. from buy to neutral, at ¥2,788, on declining earnings growth. The Osaka-­based transmission maker’s stock fell 3.3 percent, to ¥2,697, through February. — Ben Mattlin
