The Nasdaq screeched to a halt on Thursday after a computer malfunction forced all trading to stop for about an hour.
The glitch, which occurred just after 12 p.m. EST, reportedly hit some big names-trading firms affected by the snafu included Apple Inc. and Google Inc., according to the Los Angeles Times.
Meanwhile, smaller exchanges were forced to shuffle around looking for ways to figure out just what was going on with their stocks.
The Nasdaq was up about 34 points-around 1 percent-when the computational issue arose.
What caused the malfunction is still unknown, according to the Nasdaq website, but officials have an inkling that it was due to an issue with the securities information processor-a part that publicizes stock quotes.
SEC spokesperson John Nester told the Los Angeles Times that Nasdaq was doing everything it could to get the stock exchange back.
"We are monitoring the situation and are in close contact with the exchanges," he said.
Stocks up on the New York Stock Exchange are currently trading normally, but all Nasdaq-listed stocks are down as of 3:12 p.m. EST.
According to Reuters, Nasdaq officials reported trading will resume around 3:30 p.m. EST.
