Michael Beal, CEO of London-based hedge fund Data Capital Management, speaks with Newsweek senior writer and finance editor Leah McGrath Goodman about why he isn't a fan of using proprietary data, and how traders need to have "the skill or the will" to join Wall Street's wave of quantitative traders. 

Beal was speaking at Newsweek's Artificial Intelligence and Data Science in Capital Markets conference, in London, March 2.
