Location: 3124 SC Time: 4:00-5:00pm Friday, June 15, 2018 Abstract. Modern financial markets generate vast quantities of data.  As the data environment has become increasingly “big” and analyses increasingly computerized, the information that different market participants extract and use has grown more varied and diverse.  At one extreme, high-frequency traders (HFTs) implement ultra-minimalist algorithms optimized for […]
