The Dow suffered its biggest ever intraday point drop -- 998.5 points. The market’s fall may have been exacerbated by an erroneous trades that showed some shares briefly fell to nearly zero.

The situation remained unclear long after the closing bell as the Nasdaq Stock Market and others said they would cancel multiple erroneous trades. Other exchanges scrambled to examine orders.

“We did not know what a stock was worth today, and that is a serious problem,” Joe Saluzzi of Themis Trading in New Jersey told Reuters Insider.

Indexes recovered some of their losses heading into the close to end down about 3 percent, the biggest fall since April 2009. Equities erased much of their gains for the year.

Volume soared to twice its daily average for this year and was at its highest since October 2008 when financial markets seized up after the bankruptcy of Lehman Brothers.

Some traders around the world were shaken from their beds and told to start trading amid the plunge as investors sought to stem losses in the rapid sell-off.

The Dow Jones industrial average dropped 347.80 points, or 3.20 percent, to 10,520.32. The Standard & Poor’s 500 Index fell 37.75 points, or 3.24 percent, to 1,128.15. The Nasdaq Composite Index lost 82.65 points, or 3.44 percent, to 2,319.64.
