Paisley Nardini of Tema ETFs explores AI investing, S&P 500 concentration, and how to build a portfolio around changing market risks. How can investors participate in powerful growth trends without making every holding a bet on the same outcome?

In this episode of Excess Returns, Paisley joins Jack Forehand and Justin Carbonneau to discuss the risks beneath a resilient stock market, why tomorrow’s AI winners may differ from today’s leaders, and where she sees opportunities in power and infrastructure. They also explore private-company exposure inside ETFs, the role of thematic funds alongside a passive core, and why knowing what you own matters more than the number of holdings in your portfolio.

Topics covered:

What weak market breadth reveals beneath the headline indexes
Interest rates, midterm elections, and the limits of historical market patterns
Prediction markets as a source of information for investors
AI earnings expectations, debt financing, and the risk of slowing growth
Why bonds can provide income without reliably offsetting equity risk
Small-cap profitability and the importance of quality screens
AI bottlenecks, photonics, power demand, and infrastructure investment
Private-company exposure in ETFs: liquidity, fees, and investment rationale
Using thematic strategies as satellite positions around a passive core
Portfolio concentration, investment humility, and staying flexible
