Renewed economic uncertainty is testing Americans’ generation-long love affair with the stock market.

Investors withdrew a staggering $33.12 billion from domestic stock market mutual funds in the first seven months of this year, according to the Investment Company Institute, the mutual fund industry trade group. Now many are choosing investments they deem safer, like bonds.

If that pace continues, more money will be pulled out of these mutual funds in 2010 than in any year since the 1980s, with the exception of 2008, when the global financial crisis peaked.

Small investors are “losing their appetite for risk,” a Credit Suisse analyst, Doug Cliggott, said in a report to investors on Friday.

“At this stage in the economic cycle, $10 to $20 billion would normally be flowing into domestic equity funds” rather than the billions that are flowing out, said Brian K. Reid, chief economist of the investment institute. He added, “This is very unusual.”

For a lot of ordinary people, the economic recovery does not feel real,” said Loren Fox, a senior analyst at Strategic Insight, a New York research and data firm. “People are not going to rush toward the stock market on a sustained basis until they feel more confident of employment growth and the sustainability of the economic recovery.”

One investor who has restructured his portfolio is Gary Olsen, 51, from Dallas. Over the past four years, he has adjusted the proportion of his investments from 65 percent equities and 35 percent bonds so that the $1.1 million he has invested is now evenly balanced.

He had worked as a portfolio liquidity manager for the local Federal Home Loan Bank and retired four years ago.

“Like everyone, I lost” during the recent market declines, he said. “I needed to have a more conservative allocation.”

To be sure, a lot of money is still flowing into the stock market from small investors, pension funds and other big institutional investors. But ordinary investors are reallocating their 401(k) retirement plans, according to Hewitt Associates, a consulting firm that tracks pension plans.

Until two years ago, 70 percent of the money in 401(k) accounts it tracks was invested in stock funds; that proportion fell to 49 percent by the start of 2009 as people rebalanced their portfolios toward bond investments following the financial crisis in the fall of 2008. It is now back at 57 percent, but almost all of that can be attributed to the rising price of stocks in recent years. People are still staying with bonds.

Another force at work is the aging of the baby-boomer generation. As they approach retirement, Americans are shifting some of their investments away from stocks to provide regular guaranteed income for the years when they are no longer working.

And the flight from stocks may also be driven by households that are no longer able to tap into home equity for cash and may simply need the money to pay for ordinary expenses.

On Friday, Fidelity Investments reported that a record number of people took so-called hardship withdrawals from their retirement accounts in the second quarter. These are early withdrawals intended to pay for needs like medical expenses.

According to the Investment Company Institute, which surveys 4,000 households annually, the appetite for stock market risk among American investors of all ages has been declining steadily since it peaked around 2001, and the change is most pronounced in the under-35 age group.
