| The amount of data spit out into the world each day is truly massive. From Tweets and Google searches to Instagram posts and online shopping trips at Amazon, everyone is creating "digital exhaust" through their daily activities. This information, if harnessed correctly using technology, can be incredibly valuable. It's creating a data gold rush, with companies globally expected to spend nearly $190 billion this year on software and services to analyze any sort of information that could give them an edge over their competitors. The finance industry — from hedge funds and asset managers to large banks — is at the forefront of this trend. There's a lot at stake: Cracking the code on big data could lead to larger profits, more market share, and a deeper understanding of customers. This week, our finance team will bring you a new series focused on how data is reshaping Wall Street: Hedge funds are so overwhelmed by data that they're turning to an unlikely source to help synthesize it: random people on the internet. Pricey data, slashed fees, and poor returns are hurting hedge funds' margins —and some are getting in the business of helping their rivals A startup founded by a former hedge fund manager gives traders as much performance feedback as athletes so they can make better decisions. Not everyone wants in. The opaque bond market could be the next frontier for the booming alternative-data business that's on track to grow to $7 billion Meet the JPMorgan banker with no technical expertise who's now in charge of one of the biggest data projects on Wall Street We'd love to hear your thoughts on the series.
