Two years into the aftermath of 2008's market crash, economic uncertainty persists, and many American investors remain afraid to invest in the stock market -- in the first seven months of this year, investors withdrew a whopping $33.12 billion from domestic stock market mutual funds, instead opting for "safe" investments like bonds.

According to Credit Suisse analyst Doug Cligott, "Small investors are losing their appetite for risk," even as the market rebounds. And given the rise of the individual investor over the past several decades, the contrast is all the more striking.

Following past recessions, individual investors have jumped at the chance to ride the wave of recovery. But this time around, with unemployment high, job growth stagnant, and a constant threat of market volatility, there's a general sense among small investors that stocks are no longer a "safe" and profitable bet.

Retail investors might be running for the hills, but our calculations show that institutional investors aren't spooked by current market conditions.

Based on the money flows of S&P 500 stocks, we found that institutional investors didn't add significantly to their stock positions, but they didn't sell, either. Our numbers show an average increase in institutional ownership of 0.05% for all S&P 500 stocks over the past three months.

Institutional investors, it seems, are being greedy while retail investors are being fearful. Maybe Wall Street is starting to see the public's nervousness as a buy signal?

Who's side do you want to be on?
