The Asocciated Press Twitter account was hacked a couple of minutes ago and the hacker(s) tweeted that there was a White House explosion and Obama was hurt. This tweet, within minutes, scared investors and the stock market dropped over 150 points, which is considered a huge drop, especially in a couple of minutes. I am currently trading currencies (forex) and I was almost wiped out because of this market scare. The markets recovered quickly, but it just goes to show how powerful social media is nowadays. I'm sure that people lost millions, possibly tens of millions, in just a few seconds.
