The S&P 500 Is Just 50 Stocks. The Nasdaq Is a 67% AI Bet. Kai Wu on What Else Is Hiding in Your Funds

Jay Hatfield of Infrastructure Capital Advisors makes the case for an AI "reverse bubble" and explains how earnings growth, interest rates, and valuation shape his market outlook. Rather than treating AI spending as proof of excess, he looks at contracts, financing costs, and the returns companies can earn on their investments.

Daniel Crosby explains why investors can lose money in winning funds and how to build a portfolio they can actually hold. Picking the right investment is only part of the challenge; staying with it through discomfort is where behavior can overwhelm the plan.

Ted Mortonson of Baird explains why conviction in the AI boom doesn't mean buying every dip in tech stocks.

Brian Portnoy of Shaping Wealth explores why experienced investors build very different portfolios—and what that means for your own money. In How I Invest My Money Volume Two, 25 new contributors explain how they invest their personal wealth. Brian joins Matt Zeigler to discuss what those stories reveal about the gap between an optimal portfolio on paper and one you can actually live with. From large cash reserves and paid-off mortgages to investments in their own businesses, their choices reflect family needs, career risk, and priorities that a model can struggle to capture. The conversation also explores why low-cost index funds don't settle every investing question, how financial professionals think about bonds and alternatives, and what it means to compound relationships, knowledge, and opportunities alongside money.
