Investor cash levels highest in 15 years according: Survey

Cash levels are now at 5.8 percent of portfolios, up a notch from June and at the highest levels since November 2001, according to the latest Bank of America Merrill Lynch Fund Manager Survey. In addition to putting money under the mattress, investors also are looking for protection, with equity hedging at its highest level in the survey's history.''
