Corey Hoffstein is the founder and Chief Investment Officer of Newfound Research LLC, a quantitative research and investment fund. He is also the host of the “Flirting with Models” podcast.  His most recent research is “Liquidity Cascades: The Coordinated Risk of Uncoordinated Market Participants.”  In it, he examines three popular narratives about what is driving radical swings in markets, including: The increased role of the Fed The rise of passive and index investing The growth of volatility-correlated strategies  He finds that, individually, none could explain the radical market shifts we’ve seen. However, when combined, they create a market incentive loop that is causing markets to move and react to exogenous shocks more quickly and aggressively than ever before.  Find our guest online: Twitter: @choffstein  Website: Newfound Research
