It goes without saying that 2020 was a year like no other when it comes to the markets.

On this episode, we speak with Corey Hoffstein, a fund manager at Newfound Research, which employs trend following and momentum signals in its trading. He talks about what worked and didn't last year and what that says about overall market structure.
