E190: $600 Billion Parametric CIO: Thomas Lee on Markets, Debt & Trust

52 minutes

In this episode of How I Invest, I spoke with Thomas Lee, Co-President and CIO of Parametric, a $600 billion asset manager within Morgan Stanley Investment Management. Tom walks us through how Parametric helps high-net-worth individuals access institutional-quality investment strategies, why customization is the future of asset management, and how their technology powers nearly a quarter million highly personalized accounts.

We talk about inflation myths, the credibility of the Fed, and whether the U.S. will eventually inflate its way out of debt. Tom also shares how Parametric brings tax-efficient investing and direct indexing to portfolios as small as $25,000, explains why "investments as a service" is not just a tagline, and offers valuable insights on long-term leadership, scale, and innovation.

Whether you're an institutional allocator, wealth manager, or an individual trying to understand the future of investing, this episode is packed with takeaways.
