"There's a lack of buying on the part of some institutional investors who think the Fed will increase interest rates" to fight inflation, said Bill Meehan, chief market analyst at Cantor Fitzgerald.
Adding to the anxiety, the Federal Reserve Bank of Philadelphia released a survey of economic forecasters today who predicted rising inflation during the next two years.
"There's probably not been much urgency for anybody to buy anything," agreed Philip Dow a market strategist at Dain Rauscher Wessels.
Large technology stocks bore the brunt of today's selling, but the late rally masked some of the steep declines. "After the sell-off (last April 14) these stocks were seen as safe," said Meehan. However, as today's trading showed, "within the technology sector, there's no place to hide."
"Blue chip names are really the last shoe to drop," said investment strategist Brian Rauscher of Morgan Stanley. "We still have to clean out some of the (high) valuations."

Some industry analysts think the markets will languish in light trading until the next Federal Reserve meeting in late June. "The best case for the bulls is a (Nasdaq) trading range between 3,300 and 3,700 over the next five weeks," said Pip Coburn, senior technology strategist at Warburg Dillon Read.
Rauscher of Morgan Stanley also sees rocky times ahead. "You have interest-rate concerns and a shift in sentiment towards the technology sector," he said.
"There's a general feeling of negativity that were in," said Coburn. "There's no one factor, it all kind of adds up."
