The Dow Jones Industrial Average fell 113.96, or 1.1 percent, to close at 10,782.

Cisco was the biggest Dow decliner, down 4.5 percent, after leading the pack on Wednesday amid a wave of tech optimism. The company beat analyst expectations on both earnings and revenue but cautious comments from CEO John Chambers rattled the market a bit.

He also said he is closely watching events in Europe, which accounts for 20 percent of the company's revenue.

Today, Chambers did a little damage control, saying his cautious remarks were "overinterpreted."
