Keith Fitz-Gerald, One Bar Ahead

Keith Fitz-Gerald has spent 45 years in markets, starting at Wilshire Associates and eventually building One Bar Ahead, a research publication he grew to tens of thousands of readers with no advertising. He joins Behind the Ticker with a claim that cuts against 50 years of Wall Street orthodoxy: the diversification most investors were taught to treat as gospel may be quietly costing them return.

His argument starts with a single number. Over the past century, roughly 4 percent of the companies ever publicly listed in the United States produced essentially all of the net wealth the stock market created. The other 96 percent, in aggregate, did no better than Treasury bills. If that holds, then spreading capital across hundreds of names is not lowering risk so much as diluting exposure to the handful of businesses that actually drive the outcome.

Why Diversification Broke

Keith's point is not that diversification was always a bad idea. It is that the market it was designed for no longer exists. The non-correlation that made a broad basket useful has been eroded by passive flows, zero-DTE options, ETF cross-ownership, and round-the-clock trading. When everything moves together, owning more names stops buying you protection and starts buying you the average. Concentration in a small set of must-have companies, he argues, is what the best investors have actually done all along.

The 5D Framework Behind FITZ

That thinking is now a fund. FITZ, the Fitzgerald Must-Have Portfolio ETF, launched in May 2026 in partnership with Nicholas Wealth and holds 20 to 30 names. The selection runs through what Keith calls the 5D framework, five structural forces he sees driving the next wave of economic growth, with digitalization as the master theme sitting on top of all of it.

Digitalization is also why his classifications look strange to a sector purist. Keith views Walmart as one of the most consequential technology companies in the world, not a retailer, because of how it moves data and logistics. The sector label misses it. The must-have lens does not.

The Must-Have Filter and the Exits

Getting into the fund takes more than a good story. Keith's filter looks for companies with no easy substitute, zero-to-one catalysts that create something that did not exist before, visionary leadership, and strong free cash flow. Getting cut is just as disciplined. He walks through why Intel came out of the portfolio, with the dividend cut as the dealbreaker, and why he rebalances three times a year rather than four to sidestep the liquidity drag that comes with forcing trades on a calendar.

He is candid that FITZ launched right at a market peak, and honest about how it has traded since. It is also why he frames the fund as a core equity holding rather than a satellite sleeve. For an advisor or an active investor weighing an alternative to the standard 60/40, the conversation is less a pitch than a challenge to some deeply held assumptions about what risk actually is.

Key Takeaways

• Roughly 4 percent of all US public companies have generated essentially all of the stock market's wealth over the past century, while the other 96 percent collectively matched Treasury bills.
• Keith argues diversification is structurally broken in modern markets, because passive flows, options, and round-the-clock trading have stripped out the non-correlation it was built to capture.
• FITZ holds 20 to 30 must-have names chosen through a 5D framework with digitalization as the master theme, which is why he treats companies like Walmart as technology businesses.
• The selection filter demands no easy substitute, zero-to-one catalysts, visionary leadership, and strong free cash flow, and the exit discipline is just as strict, with Intel's dividend cut cited as a dealbreaker.
• FITZ rebalances three times a year rather than four, a deliberate choice to avoid liquidity drag, and Keith frames the fund as a core equity holding rather than a satellite position.
