The Intellectual Investor
Welcome to issue #36 of The Davem Dish. Every week I share what actually works in investing based on my 20 years of wins, losses and expensive lessons. You’ll also get my thoughts on solopreneurship and life in general because the same principles apply — keep it simple, stay consistent and focus on what matters.
This is the third issue of Receipts & Reality, a recurring series where I take a finance-world claim and put it next to the reality. If you want to build an investing process that doesn't depend on anyone else's agenda, keep reading.
On a stage at the University of Chicago in 2016, two of the most decorated minds in the history of finance sat down to debate whether markets are efficient. Eugene Fama, the father of the efficient market hypothesis and Richard Thaler, the father of behavioral economics. One Nobel Prize already between them, with Thaler’s arriving the following year.
They disagreed about almost everything, except one thing. When the question turned to whether anyone can beat the market, Thaler didn’t argue. “We are in virtually complete agreement,” he said. Beating the market is a loser’s game. The professionals mostly fail after fees. Regular people shouldn’t bother trying.
You’ve heard this advice your whole life. From advisors, from index fund evangelists, from every personal finance book on the shelf. And when it comes from a Nobel laureate like Thaler, you should probably listen.
Which is why what I’m about to show you matters.
The Receipts
Let’s establish who we’re dealing with first, because Receipts & Reality only works when the target has earned real credibility and Thaler has earned more than almost anyone.
He won the 2017 Nobel Prize in economics for essentially inventing the field of behavioral economics. He co-wrote Nudge, which changed how governments around the world design retirement programs. He wrote Misbehaving, the definitive history of how psychology invaded economics. His research is the reason your 401(k) probably auto-enrolls you and auto-escalates your contributions.
He even had a cameo in The Big Short, sitting at a blackjack table with Selena Gomez, explaining how the hot hand fallacy fueled the housing bubble.
Thaler’s life’s work can be summed up in one sentence: humans are predictably irrational, and that irrationality costs them money.
And his public advice for what you should do about it has been remarkably consistent. In Misbehaving, he describes his own approach as a lazy strategy — buy mostly stocks, then stop paying attention. He recommends checking your portfolio about once a year and skipping the financial news entirely. Crossword puzzles are acceptable, he says. The stock pages are not. When Schwab asked him for advice after the meme stock frenzy, his message was to stick with mutual funds and ETFs, and that if you want entertainment, don’t play with stocks — go find a poker game.
Now here’s the other set of receipts.
In 1993, Thaler co-founded Fuller & Thaler Asset Management, where he remains a principal today. The firm’s registered trademark is “The Behavioral Edge,” and its entire pitch is that behavioral finance allows it to beat the market. Its flagship Behavioral Small-Cap Equity Fund is built to exploit the exact biases Thaler won the Nobel Prize for documenting — buying when the market overreacts to old bad news or underreacts to new good news, and screening for signals like heavy insider buying and earnings surprises.
The fund charges just over 1% annually for the investor share class. Reasonable by active management standards but also roughly twenty times the cost of the index fund Thaler tells you to buy.
So the most famous behavioral economist alive spends his public life telling you the market can’t be beaten and his private life running a firm whose entire business model is beating it.
To his credit, Thaler doesn’t hide this. He acknowledges the firm in Misbehaving, writes that he believes it’s possible to earn superior returns by exploiting other investors’ biases, notes his firm has done so successfully and then closes with four words of advice for you:
“Don’t try this at home.”
The Reality
The obvious next move would be to show you that his fund secretly stinks. It actually doesn’t.
The Behavioral Small-Cap Equity Fund has returned roughly 13.9% annualized over the past decade, net of fees. Its benchmark, the Russell 2000, returned under 8% over comparable periods. That’s a small-cap fund nearly doubling its index and roughly matching the S&P 500 — during a decade that was brutal for small caps. The fund does exactly what it says it does, and the fees, while high compared to an index fund, are actually below average for its category.
This series lives on the receipts holding up, and in this case Thaler’s fund performance is good, the fees aren’t outlandish, and the strategy has worked.
Which makes the contradiction sharper, because the receipt here is the business model itself.
Follow the money one step further than the fund. Fuller & Thaler sells mostly to institutions and advisors, so he probably won’t be taking your call trying to invest. What he’s selling you in every book and interview is the belief that the game is unwinnable for people like you and me. And when you believe you can’t compete, every one of your dollars is handed to someone else. It routes your money to the financial services industry in some form and Thaler’s Nobel certified pessimism about your abilities is the ideology that legitimizes the transfer.
Intellectual Idiots
Mark Manson published a post this spring called “Intellectuals are F*cking Idiots” that’s been stuck in my head since I read it. His argument is that intellectuals build models of the world, get rewarded for the models rather than for reality, and eventually start mistaking the models for reality itself — with the most catastrophic cases doubling down even as reality contradicts them. Paul Ehrlich predicting global famine for fifty straight wrong years. Robert McNamara’s data dashboards showing America winning Vietnam.
Finance has its own intellectual models and they come in two archetypes.
The first is the academic one: the market is efficient, you can’t win, buy the index and move on to other things. It’s taught in every business school and repeated in every retirement seminar. But the people who promote the efficiency model keep finding exemptions for themselves. Thaler runs a behavioral fund. Fama has spent four decades as a director and consultant at Dimensional Fund Advisors — a firm that charges more than index funds to tilt away from the very index he says you should hold. The model is for the masses with the exemption being for the model builders.
The second is the market pundit who makes the media rounds and can recite every detail of a company, explain in mind-numbing detail why their prediction will be correct and sell you the story. Some get so buried in analysis paralysis, they never actually take positions. Others who do invest, lose to the index because knowing everything about a company and knowing what to do at a given price, while managing your own biases, are entirely different skills. Either way, the appearance already did its job. The story attracts capital to the firm, grows the following, or whatever the marketing goal is.
Both archetypes get rewarded for the model, not for reality. You don’t have that luxury.
What His Fund Knows
Set aside what Thaler says and look at what Fuller & Thaler does.
The firm doesn’t predict anything. No macro calls, no earnings forecasts, or picking the next NVIDIA. It waits for a repeatable pattern of human error — the market overreacting to bad news on a fundamentally sound company — and buys into it. That’s the whole edge. Not information nobody else has, but discipline nobody else applies. The willingness to act on patterns sitting in plain sight.
Sound familiar? It should. It’s the same edge that I’ve been writing about in this newsletter from the beginning. The obvious question then: is that strategy really only available to a Nobel laureate’s firm charging 1% a year?
Forget obscure small caps for a minute. Look at Microsoft — covered by more than 60 analysts, owned by every large-cap index fund in existence. If markets efficiently price anything, it should be this.
In late 2021, Microsoft peaked around $349. Over the following year, recession fears and rate hikes dragged it down by roughly a third and the narrative was that big tech’s golden era was over. The business, meanwhile, kept growing revenue and earnings right through the panic. Anyone who ran the numbers could see the disconnect. The stock returned 58% in 2023 and hit new all-time highs within a year of the bottom.
Then it happened again. Microsoft closed at an all-time high of $538 in late October 2025. Within months, AI spending fears took over and the stock dropped 10% in a single day after January earnings, on results that beat expectations. By spring the drawdown had reached roughly 30%. The company was still growing, but the story had simply turned scary.
I bought shares at $359 during that selloff. As of today, the stock trades around $485 — a 35% gain in a few months, on one of the most-watched companies in the world, using no information that wasn’t available to every investor on the planet.
This is the same mechanism Fuller & Thaler charges 1% a year to exploit. The market overreacts to a frightening narrative about a dominant business, the price disconnects from the fundamentals, and the disconnect eventually closes. It happened with Microsoft in 2022 and again in 2026. It’s happened repeatedly with NVIDIA, Eli Lilly, Arista Networks and many others, which I’ve written about before. No genius required. Just a fair value calculation, a watchlist, and the patience to act when everyone else is scared.
Will this pattern repeat forever? Probably not. Nothing works forever, and the investor who assumes it will is one bad decade away from learning what Corning shareholders learned in 2000.
Which brings us to the one thing my approach has that the intellectual’s model doesn’t.
The Exit Clause
Let’s go back to Manson’s intellectual idiots. What actually ruined their reputations wasn’t being wrong — everyone is wrong some of the time. It was having no mechanism for when reality contradicted the model. Ehrlich never adapted and the model had become his identity, and abandoning it would have meant abandoning himself.
The investor version of this is someone whose stock thesis becomes their identity, who marries their stocks and who averages down forever because admitting the pattern broke feels like admitting they’re broken.
Conviction with no exit clause is how intelligent people ride positions down 60%.
My answer is structural, and by now you know it well. Every position carries a stop order — an admission, placed before ego gets a vote, that I might be wrong. If the Microsoft pattern holds, I keep riding it. If it breaks, I’m out with a defined loss and my capital back, no identity crisis required.
Why This Matters for You
Three issues into this series, a pattern is forming. Ron Baron wanted you to buy on his conviction. Jeremy Grantham wanted you to sell on his. Thaler wants you to not play at all. Three legends, three contradictory instructions, and the same underlying problem every time: you’re being asked to substitute someone else’s judgment for your own process, by people whose incentives, positions, and exemptions are not visible in the soundbite.
With Thaler, the lesson has an extra twist, because I actually agree with his research. We all are predictably irrational. Willpower really does fail. Systems really do beat discipline. I’ve built my entire approach on those truths, from automated investing to systematic exits.
Where I think he goes wrong is the last step. His research shows that individuals fail without a system to manage their behavior and he rounds down to “you can’t, so don’t try”. But you don’t need to be a Nobel laureate to build a system to do it yourself. It does take a little time and effort but the alternative is handing your money to a professional and paying a 1% a year or more, forever, for access to an edge built on patterns anyone can see.
Thaler’s four words of advice were, “Don’t try this at home.”
After everything you’ve just read, why not?
Cheers,
Andrew
This is the third issue of Receipts & Reality — a recurring series where I take a finance-world claim and put it next to the actual numbers.
Issue 1 was a famous fund manager. Issue 2 was a famous forecaster. This one was a Nobel Prize winner who says you can’t beat the market. His own fund’s returns say otherwise. What will the next receipts say? Make sure you’re subscribed for the first look.
