Big Data Is a big mess for hedge funds hunting for trade signals.
It was big data’s big moment.
the most unfathomable U.S. presidentail race in memory gave Predata, a startup firm backed by hedge fund manager kyle Bass, a chance to cut through the vitriol and coolly calculate the winner by monitoring chat data. urns out that Predata, which anointed Hillary Clinton the likely victor days before the Nov.8 vote, was no smarter than the cable news pundits.
The bad call is a reminder of the pitfalls hedge funds face as they try to profit from a world awash in data. After years of sluggish returns, firms seeking fresh ideas are joining the data revolution, tapping the torrent of social media, setellite and personal information already used by airlines to forecast ticket sales and health experts to track illnesses. But so far few managers have mastered the art of spotting cleare trading signals buried in all the noise.
There are those who realize their industry is changing and their fund isn’t going to exist if they don’t adapt, said Matei Zatreanu, who led data efforts at 19 billion hedge fund King Street capital mangement. But not many of them know what they are doing, except a few. Two sigma, which says it was exploiting big data before it was a buzzword, is one of the handful. The 37 billion hedge fund has otperformed rivals partly by using machine-learning algorithms to find trading signals in the data. Now traditional hedge unds, which have relied on information such as company filings and shopping surves, are on the hunt.
