Investors pulled their dollars out of mutual funds over the past week, apparently fearful about the state of the economy.Stock funds saw a $580 million walk out the door the week ended Wednesday, net of purchases. That reversed a small part of the $14.58 billion they took in the the previous week, according to TrimTabs Investment Research of Santa Rosa, Calif. The Dow Jones Industrial Average closed at 13,444.96 Wednesday, compared with 13,289.45 on Nov. 28. All of the redemptions came from funds that invest primarily in U.S. stocks, which saw a net $2.28 billion walk out the door. That was an about-face from the previous week, when investors added a net $7.42 billion. Vincent Deluard, global equity strategist at TrimTabs, said that if the current trend continues, it will result in eight months of straight outflows from U.S. funds, something that hasn't happened since the Black Monday stock market crash in 1987. He said the numbers apparently indicate the consensus view of the U.S. economy. "In the past six months that view has been rather gloomy," he said. "So much money has gone out of U.S. equity mutual funds, you have to believe it's going to come back at some point."
