in case anybody was interested. http://www.bloomberg.com/news/marketsmag/mm_0410_story1.html Cohenâs natural ability as a tape reader has been a big part of his success, former employees say. In addition to trading his own stocks and overseeing 300 managers, analysts and traders globally, Cohen buys and sells âminis,â says one former employee. âMiniâ is short for a security called the S&P 500 E-mini future, an electronically traded derivative that rises and falls with the Standard & Poorâs 500 Index and is sold in smaller units than other index futures. See, the mini's are not for suckers after all!
