Cash levels as a percentage of total assets in stock mutual funds is bordering on an all-time low. When was that low hit? It was July 2007 โ€“ three months prior to the last bull market high. The dry powder in stock mutual funds that helped fuel a 72% rise in the S&P 500 from the March 2009 lows is spent. Individual investors still have dry powder, but theyโ€™re flocking to bonds and hoarding cash. Two vicious bear markets in 10 yearsโ€™ time will do that. Stocks could move higher if individuals move aggressively back into the market, but if you are forming a long-term investment plan on the basis of what others may do, you are speculating, not investing.
