On May 23, 2013, a series of tweets from the Associated Press (AP) Twitter account announced that there had been two explosions at the White House and that President Barack Obama had been injured. The tweets caused widespread panic and led to a brief but significant drop in the stock market.
Within minutes, the Dow Jones Industrial Average had fallen by more than 100 points, and other major indices were also down sharply. The drop in stock prices was due in part to the shock and uncertainty caused by the news of the explosions, but it was also exacerbated by computer trading algorithms that automatically sold off stocks in response to the news.
As it turned out, the tweets were a hoax. The AP Twitter account had been hacked, and the tweets were sent without the authorization of the AP. However, the damage had already been done. The stock market had been briefly disrupted, and investors had lost millions of dollars.
The Twitter hack was a reminder of the vulnerability of financial markets to manipulation and false information. It also showed how computer trading algorithms can amplify these effects, making it possible for a single event to have a disproportionately large impact on the market.
The SEC is investigating the Twitter hack and has subpoenaed the records of the 20 trading firms that made the most money from the market drop. The SEC is also looking into whether the firms violated any securities laws by trading on the basis of false information.
The Twitter hack is a complex case that raises a number of important issues. It is important to understand the events of that day in order to prevent similar events from happening in the future.
