Episode notes

Corey Hofstein is the co-founder and chief investment officer of Newfound Research. In season three, episode 11, he spoke with Omar Seder who argues that equity quants have done precisely that. The mass adoption of factor models has fundamentally changed how baskets of stocks are bought and sold. For discretionary managers to ignore this sea change is to ignore a fundamental shift in the current of the waters in which they swim.

After March 2020, a growing research interest of mine was the question, “how do strategies reflexively impact the markets they trade?” Beyond crowding risk, can adoption of strategies fundamentally change market dynamics.

In Season 3 Episode 11, I spoke with Omer Cedar, who argues that equity quants have done precisely that. The mass adoption of factor models, whether for alpha or risk, fundamentally changed how baskets of stocks are bought and sold. For a discretionary manager to ignore this sea change is to ignore a fundamental shift in the current of the water they swim in.

In this clip from the episode, Omer discusses how quants have changed the market and how fundamental managers should use this information to sharpen their edge.
