How Data, Discipline, and Human Ingenuity Shape Long-Term Wealth, Ep #267

| |

In a world where gut instinct once ruled the day—from football coaches making pivotal fourth-down decisions to investors choosing their next stock pick—a revolution has reshaped the landscape: reliable data and analytics. Drawing inspiration from the principles behind the film Moneyball and a recent article by David Booth on 3 Lessons from Investing’s Moneyball Moment in Fortune magazine, I break down what a century of US stock market history reveals for everyday investors.

 

Lesson 1. Insiders Aren’t Smarter Than Outsiders

 

One of the key insights unearthed from this century’s worth of data is simple but profound: experts, or “insiders,” don’t consistently outperform the market. Early research using the University of Chicago’s Center for Research on Security Prices (CRSP) data found that, on average, mutual funds and clever stock pickers failed to beat the simple strategy of buying and holding a diversified market portfolio. 

This led to the explosion of index funds, notably pioneered by Vanguard and enabled by firms like Dimensional. Now, anyone, not just Wall Street professionals, can own broad, low-cost portfolios and harness the long-term growth of the entire market rather than trying (and in most cases, failing) to outsmart it.

 

Lesson 2. Bet on Human Ingenuity

 

Human creativity and progress power the market’s reliable returns over the decades. Companies go public to raise money, which they funnel into improving their products and expanding their reach. Every day, millions of people at thousands of companies are seeking better ways to serve their customers and grow profits.

When you invest in the stock market, you’re ultimately betting on people’s ability to innovate and adapt to a changing world. This century-long experiment in collective growth has consistently delivered average returns of around 10% per year, a number that’s survived wars, recessions, inflation spikes, and bubbles.

 

Lesson 3. Investor Behavior Is Key

 

If reams of data tell us anything, it’s this: reliable, long-term returns belong to disciplined investors. The journey is never smooth—market downturns feel chaotic and alarming in the moment. Yet, $1,000 invested in 1926 would have grown to over $17 million by 2025, despite wars, crashes, and global crises.

Most investors who stuck with the market over any 10- or 20-year span came out ahead. Stay disciplined, trust the data, and know that while the challenges may look different, the power of long-term, patient investing is timeless.

About the author, Scott Wellens

Scott Wellens, CFP® is an investment advisor and founder of Fortress Planning Group. After earning his Bachelor of Science degree from the University of Wisconsin-Oshkosh, Scott quickly ascended to become a Vice President of North American Sales at a major regional provider of telecommunications infrastructure. While financially successful in this role, Scott searched for ways to pursue his passion related to financial literacy and providing financial freedom for both his own family and others. During his search, Scott became curious about the significant gap he found in the financial services sector: he was unable to find a comprehensive financial planner that maintained a family stewardship lens without being attached to financial products. Scott decided to fill that gap by creating his own planning firm that maintains a strong passion for comprehensive, unbiased wealth planning that is genuinely client-centered.

Scott resides in Menomonee Falls, WI with his family. He is the father of three active and independent daughters who keep him on his toes. Scott is an active community member, serving on the Hamilton Education Foundation Board, serves as a Dave Ramsey Financial Peace facilitator and leads the All Pro Dad’s group at their local elementary school. Scott enjoys spending his free time visiting state parks with his family, reading, and watching the Milwaukee Bucks and the Green Bay Packers win ball games.
