Christopher CerasoCredit SuisseChristopher Ceraso debuted as a runner-up in 2011 and zooms to the No. 2 spot this year. The Credit Suisse analyst told investors to buy Delphi Automotive at its initial public offering in November, when shares of the U.K.-based parts manufacturer were expected to fetch between $22 and $24 each. They closed the first day of trading at $21.33, but Ceraso stood by the call — arguing in favor of the company’s “product portfolio that helps automakers improve fuel economy, safety and connectivity” — even as the stock drifted until mid-January. Then it began to gain traction, zipping to $32.33 in March before starting to reverse. It had slipped to $30.29 by the end of August for a life-of-call gain of 42 percent that sped past the sector by 43.3 percentage points. “Fantastic!” declares one grateful client, who adds that the call “was a real moneymaker in an environment that turned tough in a hurry.” Ceraso remains bullish.
