- How Big Data Controls Stock Markets: Big data and technology govern the markets like never before. Between stalactite data and scanning social media, investment firms now do whatever it takes to gain the upper hand over their competitors. Today, more than $5.3 trillion dollars shuffles around stock markets a day, mostly by high- frequency trading algorithms. And with that kind of money on the line, investors have literally trillions of reasons to try and gain a competitive advantage, and over the last decade, they’ve turned to big data. But in a modern surveillance state, there’s near-infinite amounts of data, so what information is even valuable and how do you make use of it. Companies have turned to satellite surveillance and combing social media for any data that could help them predict the next market movement.
