Stocks Are Falling. The Economy Is Weakening. So Why Doesn’t Mike Green See Passive Flows Turning?
Excess Returns
· · 55 min · Hosts: Matt Zeigler, Justin Carbonneau · Guests: Mike Green
Summary
Mike Green argued that passive investing is increasingly shaping stock prices, market concentration, and even the path of IPOs. He said the system now forces retirement and index flows into the biggest companies, while liquidity does not scale fast enough with market cap, so the largest stocks keep absorbing more buying pressure. In his view, that helps explain why giant IPOs can come public while smaller offerings struggle, and why market behavior increasingly looks mechanical rather than informational.
He also said the current mix of target-date fund allocations, retirement contributions, and low unemployment has kept passive flows stronger than many investors expect. Green argued that a rise in unemployment, especially among middle-aged workers, would be the main catalyst that could slow those flows. Until then, he expects the system to keep supporting large-cap equities and potentially produce another rally in AI-related names when major private companies go public.
Green described Tier 1’s framework as a “passive-aware” approach that tracks roughly 4,000 ETFs and funds and makes small tilts around those flow effects. He said valuation still matters, but only after accounting for the mechanical impact of fund flows, liquidity, and market structure. He was also cautious on inflation, AI capex ROI, and Fed policy, framing all three as deeply shaped by market structure, regulation, and concentration.
Key takeaways
- Green said passive flows now matter more than security selection because fund selection increasingly determines where capital actually lands.
- He argued that giant IPOs like SpaceX and Anthropic are being enabled by index mechanics and forced demand, while smaller IPOs face a tougher path.
- Green said the key catalyst that could weaken passive buying is a meaningful rise in unemployment, especially among middle-aged workers.
- He said Tier 1 is tracking about 4,000 ETFs and funds to estimate how incremental flows affect individual securities.
- Green argued that value and size underperform because passive allocation systematically pushes capital toward large-cap names and away from smaller ones.

How the episode opens
You're watching Excess Returns, the channel that makes complex investing ideas simple enough to actually use, where better questions lead to better decisions. I'm Matt Ziggler. Justin Carbono is here with me today. There's only one man to call when you need to connect fuagra policies and passive flows post midterms. And that man is the founder and CEO now of Tier One Asset Management. Big round of applause for that, Mike Green. Welcome back.
It's pleasure to be here, guys. Thank you. I always love your intros, Matt. — Fogra, you agra guy. Is this is this in your repertoire? — Really good fog. Absolutely. — Like whether I sear it myself or I actually make pate on occasion, but like you know my my pate is
Good largely because I corrupt it by doing things like sautéing mushrooms and mixing it in to you know extend the flu bra portion of it so that it can serve the crowd. But uh you know it's certainly not my primary skill set.
Okay. Well, for our other show, cooking fuagra, we'll save the rest of that segment. I know this was a ballot item, so for the DC and the the Denver people just go find us on the other podcast, but let's start with the midterm elections. Any implications for markets that are obvious from this or just noise?
Well, I think I think there's two separate components though. one there is a fair amount of hedging going in. The short day and index zero day options were remarkably rich. I think we were preding 26 on the one day VIX that's very hard to sustain and so the rally today can largely be thought of in my view at least as a reaction to the removal of those hedges.
