"...Stealth buying intensifies as 54 new institutional investors quietly acquire shares of Washington Mutual (WM), according to NASDAQ Detailed Institutional Holdings. That’s an astounding 567 institutional investors now holding 52% of the company. Toscafund Asset Management LLP, a British based value player, reportedly snatched up 105.5 million shares, or a 6% interest. Spotting stealth activity requires painstaking analysis. The majority of investors fail to recognize stealth activity until it’s publicly disclosed. The wholesale accumulation of WaMu shares trumpets a clear “Buy Signal.”"
