1. August 22, 2013: The Three-Hour Meltdown
Today the NASDAQ experienced a glitch that shut the exchange down completely for more than three hours.
Just before noon the exchange began experiencing “momentary interruptions” distributing stock quotes, which then spiraled into a three-hour halt on trading for the thousands of companies listed on the NASDAQ, including Microsoft, Apple, and Google.
2. October 2012: Kraft Bug
After recently switching to the NASDAQ, Kraft Foods stock was hit by a glitch that caused the share price to skyrocket 30% in one minute and resulted in the cancellations of orders as a result.
NASDAQ blamed the error on a broker, but the snafu came on the heels of the exchange’s massively public botched IPO of Facebook, and a day after the Securities and Exchange Commission had a roundtable on fixing computer errors on the exchanges, conjuring fears of technological failings in many market watchers.
3. August 2012: Peet’s Coffee Skyrockets
Another glitch that sent share prices soaring occurred in the summer of 2012, this time with Peet’s Coffee & Tea stock, causing more order cancellations.
4. May 18, 2012: The Botched Facebook IPO
This one was a doozy. After weeks of anticipation, the much-hyped Facebook IPO fell completely flat when a technical error that NASDAQ subsequently ignored caused massive confusion on the trading floor.
As a result, NASDAQ was fined $10 million by the SEC and agreed to pay $62 million to brokers who lost money in the debacle.
5. January 2011: The Big Freeze
Trading on the NASDAQ froze one winter morning in 2011, when a glitch in the system failed to get index updates out to various outlets.
6. August 1994: Squirrel Number Two
The summer of 1994 included a major glitch for NASDAQ when another squirrel shut down trading for 34 minutes after chewing through a power line connected to the trading floor.
The exchange’s backup system in Connecticut was no match for the animal, and didn’t kick in for more than a half hour.
7. December 1987: Squirrel Number One
The first squirrel appearance on NASDAQ’s radar was in December of 1987, when one chewed through a power cord linked to the exchange, causing an outage for 82 minutes.
At the time, a NASDAQ official estimated that the squirrel prevented more than 20 million shares from being traded.
