Bloomberg News says that Americans are hoarding $3.5 trillion in cash, "giving money managers increasing confidence that the stock market rally under President Barack Obama will continue through the end of the year." One investor said, "There’s an enormous stockpile of liquidity on the sidelines. The reinvestment of cash could help fuel the market." And there's even smack-talking about some cautious investors, with one sniffing, "Many of the fund managers I talk to that have missed this rally or underplayed this rally are sitting with way too much cash."
