Stocks slumped as the protests in Egypt raised concerns the government was losing control, which would lead to instability in the region. The news was roiling markets worldwide.
The uncertainty surrounding the events also gave investors a reason to sell after five months of solid gains, and as the Dow and S&P bumped up against key thresholds, analysts said.
That and weak earnings news out of Amazon.com, Ford and Microsoft, provided another catalyst for investors to sell, said Ryan Detrick, senior technical analyst at Schaeffer's Investment Research.
The selling—which came from big institutions—was taking place amid significant volume, indicating more conviction in the moves, Detrick said.
"Egypt is definitely at the forefront today," agreed Paul Brigandi, senior vice president of portfolio management at Direxion Funds/Direxion Shares. "Overall, political unrest is never good for the market, especially when it has to do with the Middle East."
But the events in Egypt hit at a time when the market was bumping up against psychologically important benchmarks, and was beginning to "look fatigued" after rallying for some eight or nine weeks, said Brigandi, noting that the S&P 500 had been up 3 percent so far this year on top of a nearly 13 percent gain in 2010.
"The general consensus in the market is that a pullback was expected," Brigandi said. "And seeing a headline like this is giving people reason to believe this and sell risky assets."
In fact, many of the sectors that had outperformed in 2010—including the riskiest assets, such as small caps and emerging markets—fell the most on Friday. The Russell 2000 Small-Cap Index, for instance, slumped 2.5 percent.
Commodities, however, spiked as investors returned to safer assets, including oil, gold and bonds. Gold prices rose above $1,325 an ounce and oil prices rose to more than $89 a barrel. The dollar , however, gained against a basket of currencies.
Apache, an independent energy company with significant exposure to Egypt, fell more than 4 percent early in the session, but came back a bit.
Also, stocks of tanker companies rose on speculation the Suez Canal could be closed as a result of the unrest in Egypt, which would boost demand for tankers. The Suez Canal is used to transit oil and fuel from the Persian Gulf to the West. Among the rising stocks were: Overseas Shipholding Group and General Maritime .
