David Errington, Chen Luo & team Bank of America Merrill Lynch

The buy side says: “Quick responses and good access to management.”

David ­Errington, 48, and new co-leader Chen Luo, 35, pilot Bank of America ­Merrill Lynch’s group of 15 to a ­second consecutive first-place finish. Clients say that ­Errington, who works out of Melbourne, “has a great handle on the big ­Australian supermarkets” and that Hong Kong–based Luo “is always enthusiastic about presenting his latest ideas.” The squad covers more than 60 companies, and current top picks include ­Chinese retailer Wumart Stores, which the ­analysts upgraded from neutral to buy in February 2011, at HK$14.95, on its steady growth outlook and quality operations, among other considerations. The stock climbed 13.3 percent, to HK$16.94, through March 2012. Errington has a master’s degree in commerce from the University of ­Melbourne; he joined BofA Merrill in 1991 from National Australia Bank. Luo, who received a master’s in business management from China’s Nanjing University, went to the firm in 2004 from ­BearingPoint. — ­Leslie Kramer
