Is now the time investors should move to cash?

Long gone are the days when most companies looked cheap and buying equities was a no-brainer. Now stock markets are at all-time highs and index valuations are closing in on their historical norms.

Many investors are, understandably, nervous about where stocks are headed. Thanks to several wars overseas, as well as Argentina's recent debt default and just general nervousness about markets and the economy, the S&P 500 has dropped nearly 2 percent over the last month.

Moves like that have caused some people to ask themselves whether or not they should put more of their money in cash. Even Friday's market rally is not affording any peace of mind.


It's a question that Irwin Michael, a deep-value portfolio manager with Toronto's ABC Funds, has been pondering lately, too. In the past, finding bargains was easy; it's getting harder today. "A year ago we would look at five stocks and buy two. Now we're looking at 10 to buy one," he said.

While he said that there are still places to deploy capital-mining and oil and gas, for instance-he's also not afraid to hang on to cash and wait for an opportunity to arise.

At the moment, Michael has only 2 percent of his portfolio in cash, but he said that he's not afraid to hold up to 10 percent of the asset class.

In fact, his cash allocation may rise in the near future. He's considering selling a couple of stocks, he said, and while he has his eye on some other buys, he's not quite ready to pull the trigger.

"Cash gives us time to think, so we'll hold it as long as necessary," he said.

There's one big danger with moving money out of stocks and into cash: If the market continues to rise, your portfolio won't benefit from those gains.

Of course, no one has any idea where stocks are going, and just because the experts are nervous about a hot market, it doesn't mean things will go south.

In 1996 Alan Greenspan, the then Federal Reserve chairman, talked about the "irrational exuberance" of the market and told people to be careful about stocks. Whoever sold out that day would have lost out on nearly four years of stellar returns.

"It's a very slippery slope for people," said Larry Swedroe, director of research for St. Louis-based Buckingham Asset Management. "There's plenty of evidence that shows that investors shouldn't time the market."

At the moment, just 3 percent of America's 7,500 equity funds have more than 10 percent of their assets in cash, said Todd Rosenbluth, S&P Capital IQ's director of ETF and mutual fund research, and many of those funds have underperformed the market over the last year.
