Today Wall Street is ruled by thousands of little algorithms, and they've created a new market—volatile, unpredictable, and impossible for humans to comprehend.Photo: Mauricio Alejo Last spring, Dow Jones launched a new service called Lexicon, which sends real-time financial news to professional investors.
This in itself is not surprising. The company behind The Wall Street Journal and Dow Jones Newswires made its name by publishing the kind of news that moves the stock market.

They don’t need their information delivered in the form of a story or even in sentences.

The study looked at only the expiring contracts (which trade electronically on the Chicago Mercantile Exchange) that are used to bet on the direction of the Standard & Poor’s 500 Index. The researchers also did something they’d never been able to do before: Use actual trading data from individual firms, though none were identified.
