Larry Fink, BlackRockâs founder and chief executive, on Tuesday took aim at the âluxuriousâ trading profits enjoyed by Wall Street banks, saying that they have taken advantage of reduced competition to charge their customers more for even basic trades. âThere are fewer players. There is very little capital being committed by these dealers,â Mr Fink said. âTheyâre just taking the spread between the bid and the ask [the price gap between buyers and sellers] and they are making very luxurious returns,â he added. Mr Fink, who made his comments as BlackRock reported better-than-expected second-quarter results, added that he was looking at ways to reduce that spread to save his clients money. http://www.ft.com/cms/s/0/11977bd6-764a-11de-9e59-00144feabdc0.html ItÂ´s about time for a new powerhouse on Wall Street.
