Carlos Constantini & team  Itaú Securities

Previously unranked, the 27 Itaú Securities analysts based in São Paulo and guided by Carlos Constantini take third. In March the team recommended exposure to domestic companies — especially diagnostic-­medicine provider Diagnósticos da América, at R14.80, largely because of its high return on invested capital. In early July, after the stock had surged 20.9 percent, to R17.90, the analysts deemed the shares fully valued and removed Dasa from their recommended portfolio; by the end of that month, the stock had slipped 5.5 percent, back to $16.91. “A seasoned strategist, Carlos is also skilled at buying low and selling high,” cheers one grateful client.
