Why 4% of Stocks Drive 100% of Returns — And How to Own Them | Keith Fitz-Gerald, One Bar Ahead

Keith Fitz-Gerald has spent 45 years as a global investor, researcher, and strategist — starting at Wilshire Associates, building One Bar Ahead from a yellow pad in his dining room into a publication read by tens of thousands worldwide, and earning a quiet reputation as one of the most independent voices in the business. Suze Orman called him "someone you should pay attention to" on her podcast, and that recommendation triggered the kind of viral moment most publishers spend a career chasing.In this episode, Keith walks through the research that underpins his entire investment framework — the finding that roughly 4% of US publicly listed companies have contributed essentially 100% of the wealth created in the stock market over the past century — and what that means for how investors should actually allocate capital. We get into why he believes diversification has become a problem rather than a solution, how the structural changes in modern markets (passive flows, zero-DTE options, ETF cross-correlation, 24-hour trading) have eliminated the non-correlation that diversification was originally designed to capture, and why concentration in must-have companies is the path the industry's best investors have quietly taken for generations.Keith then breaks down FITZ — the Fitzgerald Must-Have Portfolio ETF, launched in May 2026 in partnership with Nicholas Wealth and David Nicholas. The fund holds 20 to 30 names selected through the 5D framework: digitalization, plus four other structural drivers Keith identifies as the foundation of the sixth wave of human economic evolution. He explains why companies like Walmart get classified as retail and missed by sector-driven allocators when they're actually among the most consequential tech companies on the planet, why Intel got cut from the portfolio, why he rebalances three times a year instead of four, and why he sees FITZ as a core equity holding rather than a satellite sleeve.Full episode page, with the complete transcript: thorft.com/podcast/why-4-of-stocks-drive-100-of-returns-and-how-to-own-them-keith-fitz-gerald-one-bEvery episode: thorft.com/podcastBrad's daily market note: The Signal
