Claim◆Audio · 34:00 — 35:30

The optimal portfolio construction for factor investing is concentrated (30-50 holdings) with high active risk, not broadly diversified sector-neutral approaches, because the edge comes from being different and enduring pain.

Wes argues that concentrated portfolios with 30-50 holdings maximize active risk exposure without being reckless, and that excessive sector-neutral constraints dilute the factor premium. The real value-add comes from being willing to hold the unloved, painful bets that diversified mandates avoid. ✦ AI generated

“So how do you think about that? So is there any risk management that you do or?”

We just feel that if you're going to try to bottom ticket and give people as much active risk exposure as possible without being insane or running afoul of these different rules we have to operate within the regulated space, we think like kind of that 30 to 50 seems reasonable. And could you do 100? Sure, that's not bad. That's at the margin better than 500 where you got sector neutral everything and you're not really buying the factor.
