Morgan Stanley (MS) is planning to reduce its stake in the FrontPoint Partners hedge fund it bought four years ago, the Wall Street Journal reported. The move comes as rival Goldman Sachs (GS) considers spinning off, winding down or moving its proprietary trading desks, the paper said. The Volcker rule, named after former Fed chief Paul Volcker (right), limits the amount of money federally insured banks can invest in riskier structures such as hedge funds and private equity investments and in trading with their own funds.
