The biggest mistakes beginner investors make—and how to avoid them (Paul Merriman)

Most of what people believe about investing is wrong, and the wrong beliefs are expensive. Paul Merriman, founder of The Merriman Financial Education Foundation, has spent sixty years around markets and more than forty of them teaching people how to invest. He opens this conversation with Jack Lempart by naming his own biggest mistake: a scarcity mindset that has kept him fifty-fifty in stocks at eighty-two, when by his own reckoning he should probably be fully invested. From there the myths come apart one by one, with numbers attached: why the casino comparison runs exactly backwards, what a hundred dollars a month from a first paycheck compounds into (about three million dollars at eight percent, and thirty-seven million at the twelve percent Paul says is possible in small cap value), and why only about one active manager in ten or twenty beats the index over the long run with no way to spot them in advance. Paul also explains what actually sits inside an ETF once you stop treating the wrapper as the product, why a half-US, half-international portfolio changed when the returns arrived rather than how large they were, and why the small cap value premium has gone missing four times in roughly a century for stretches averaging seventeen years. This is an episode for anyone who has ever said "it's a bad time to invest", "I don't have enough to start" or "I'm not smart enough for this", and for the experienced investor quietly losing faith in a lagging strategy. It ends with the one thing Merriman asks you to do tomorrow morning with your coffee: list what you can actually control, and automate everything you can.

In this in‑depth conversation, Irish financial educator Dan shares his journey from auditing global funds at PwC to building Honest.ie, a platform devoted to independent personal‑finance education. Drawing on his background as a chartered accountant and tax adviser, Dan explains how he translates complex financial ideas into simple, actionable advice for ordinary people. The discussion covers everything from budgeting, debt, and housing decisions to ETF investing, pensions, and tax efficiency. Dan also opens up about what “honesty” means in practice — staying free from product bias while building trusted tools and educational content. Listeners learn how to create a simple, lasting financial system, avoid common behavioural traps, and take advantage of pensions as a powerful wealth‑building tool. Throughout, he argues that independence, transparency, and consistency matter more than chasing the next market trend.

This in‑depth conversation with JL Collins traces his journey from early lessons watching his self‑employed father struggle, through his own decision in his twenties to live on half his income and relentlessly invest the rest. Jack and JL unpack the core ideas behind The Simple Path to Wealth: F‑You Money as the foundation of freedom, the power of very high savings rates, and why a single broad US index fund like VTSAX (or its ETF twin VTI) sits at the center of his philosophy.

This comprehensive presentation challenges the common assumption that investing exclusively in U.S. equities through the S&P 500 is the optimal choice, instead advocating for a globally diversified approach using ETFs like MSCI ACWI. While acknowledging that U.S. stocks have delivered superior returns (10.48% CAGR vs. 8.95% for developed markets) over the past 100 years and currently represent 60%+ of global market capitalization, we emphasizes that historical dominance is no guarantee of future performance—citing Japan's decline from 30% to 5% of global market cap as a cautionary tale.

The episode explains why traditional schooling teaches many abstract subjects but almost no practical money skills, even though everyone must manage money for decades. It shows how even “small” inflation, like 3% per year, slowly destroys the value of cash, so doing nothing is actually losing money. Because of this, we are all forced to invest and choose between different assets like stocks, bonds, real estate, and managed futures.We argue that stock picking and trying to “beat the market” usually fails, even for professionals, mainly because markets are very efficient and fees are high. Instead, the proposed solution is simple index investing: buying ETFs that own the whole market and letting the index automatically remove losers and add winners. A “boring” diversified portfolio of global stocks, managed futures, and bonds, rebalanced once a year, has historically delivered strong returns with manageable risk.
