The best part was when all the naive people that took that news without any confirmation and started selling off stocks like crazy. I'm going to guess that some of them, looking for someone to blame other than their own selves, will possibly try to sue twitter to get their money back.
High frequency trading my friend. It accounts for nearly 80% of all stock market volume today. Any glitch in the news and it reacts within miliseconds. In this case, resulting in a lot of stop loss trips and further selling.
