An absurd example you note that highlights the role algorithms play in unhinging prices from reality is Anne Hathaway’s connection to Berkshire Hathaway’s stock value. Bad news for the actor gets translated into bad news for the company just because they share a name! Speculators I spoke with said if you really want to understand how markets work, you’ve got to understand how Berkshire Hathaway is correlated to Anne Hathaway’s film career. Whenever an Anne Hathaway films come out, Berkshire’s Hathaway stock gets a bump. And when bad things happen to Anne Hathaway, like when she got into a car accident, Berkshire Hathaway’s stock goes down. What they’re saying is they have algorithms that are reading headlines – think Reuters, Bloomberg stories – that are fed into the computer and can detect whether it’s a negative or positive story and trade accordingly.
