The US-based podcast network Excess Returns released a new episode on October 23, 2026, featuring Shaping Wealth founder Brian Portnoy in conversation with host Matt Zeigler. The discussion centers around the upcoming book 'How I Invest My Money Volume Two', which collects stories from 25 finance professionals about their personal wealth allocation.
According to the publisher's show notes, the dialogue focuses on why knowing how markets work does not produce one right portfolio for everyone. Listed topics include 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.
Specifically, the episode covers choices such as large cash reserves, paid-off mortgages, and investments in their own businesses, reflecting family needs, career risk, and priorities that models struggle to capture. It also addresses the difference between spreadsheet optimization and a portfolio you can stick with, as well as the trade-off between security and opportunity cost when paying off a mortgage.
