Wall Street collided with social media on Tuesday, when a false tweet from a trusted news organization sent the US stock market into freefall.
The 143-point fall in the Dow Jones industrial average came after hackers sent a message from the Twitter feed of the Associated Press, saying the White House had been hit by two explosions and that Barack Obama was injured. The fake tweet, which was immediately corrected by Associated Press employees, caused a sensation on Twitter and in the stock market.
White House officials were unimpressed. An AP reporter apologized for the Twitter hacking at the start of the daily White House press briefing, saying the tweet had been deleted as soon as it was discovered. A stoney-faced Jay Carney, Obama's personal spokesman, thanked the reporter but did not look amused. "The president is fine. I was just with him," added Carney.
The market recovered within a few minutes of the misunderstanding, but the incident left traders catching their breath and speculating once more about their vulnerability to breaking news in the age of social media. It also raised new questions over Twitter's security procedures.
The panic, however brief, demonstrates how tightly intertwined Wall Street has become with Twitter, a site that acts as both chatroom and news service, where journalists and publications regularly send out breaking news.
