The research I lectured on at Oxford is built into how you invest.
Most investment programmes are built on opinion. This one is built on the academic work of Nobel laureates — Daniel Kahneman, Eugene Fama and Richard Thaler — the same behavioural finance research I taught as a Visiting Fellow in Business at Corpus Christi College, Oxford. It is the difference between a system that tells you what to buy and a system that stops you destroying your own returns.
Not a marketing line. A teaching post.
I read at Oxford as an undergraduate. Years later I returned in a very different capacity — as a Visiting Fellow in Business at Corpus Christi College, one of the University's oldest colleges, founded in 1517.
A Visiting Fellowship is not an honorary title bought with a donation. It is a working academic appointment: you lecture, you contribute to the intellectual life of the college, and you are expected to bring something the University values. What I brought, and what I taught, was the practical application of behavioural finance — the study of how real human psychology collides with the supposedly rational world of markets.
That distinction matters enormously for your money. There is a vast difference between someone who read a popular book on investor psychology and someone who stood at the front of an Oxford lecture room and taught the source material. The Great Investments Programme is the only retail investment programme I know of that is built, from the foundation up, on that body of academic research rather than on gut feeling.
Markets don't lose people money. People do.
Decades of Nobel-winning research point to one uncomfortable conclusion: the single largest drag on a private investor's returns is not the market, the fees, or the stock selection. It is their own behaviour. Panic-selling at the bottom. Chasing winners at the top. Holding losers too long. Selling winners too early. The Oxford research doesn't just describe these mistakes — it predicts them, names them, and gives you the tools to design around them.
Three Nobel laureates. One investing system.
These are not obscure academics. They are the most decorated names in the history of financial economics, and their work forms the intellectual spine of how the Great Investments Programme is built. Here is each, in plain English, and exactly how their research is applied to your portfolio.
Daniel Kahneman
Kahneman, a psychologist, won the Nobel in Economics for showing that human decision-making under uncertainty is systematically, predictably irrational. His Prospect Theory (with Amos Tversky) proved that we feel the pain of a loss roughly twice as intensely as the pleasure of an equivalent gain — a phenomenon called loss aversion.
He also gave us the model of System 1 and System 2 thinking: the fast, emotional, instinctive mind that panics in a sell-off, and the slow, deliberate, analytical mind that should be making investment decisions but usually doesn't get a say in the heat of the moment.
The programme is deliberately engineered as a System 2 process: written rules, defined entry and exit criteria, and monthly cadence — so decisions are made by the analytical mind in calm conditions, not by the panicking mind in a crash. Loss aversion is why we set exits in advance, before you are emotionally invested in a position.
Eugene Fama
Fama is the father of the Efficient Market Hypothesis — the idea that prices already reflect available information, which is precisely why beating the market through frantic short-term trading is so difficult and so expensive. His work is the rigorous, rational counterweight to the behavioural school.
With Kenneth French, he also identified the factors that genuinely explain long-run returns — value, size, and profitability among them — rather than the noise that day-traders chase. This is the empirical backbone of disciplined, factor-aware, long-horizon investing.
Fama is why the programme is built on Low-Frequency Investing, not trading. We don't try to out-guess an efficient market minute by minute. We screen for the durable factors his research validated — value, quality, momentum — and we hold. The category name itself, LFI, is a direct nod to this work.
Richard Thaler
Thaler built the bridge between Kahneman's psychology and real economics. He showed how mental accounting — the way we irrationally treat money differently depending on where it came from — distorts investment decisions, and how the endowment effect makes us overvalue what we already own, so we cling to losing positions far too long.
His most famous practical contribution is the nudge: the insight that you can design the environment around a decision so that the easy, default choice is also the wise one — without removing anyone's freedom to choose.
The entire structure of the programme is a series of nudges toward good behaviour: defaults that favour patience, processes that make the disciplined choice the easy one, and a monthly rhythm that nudges you away from compulsive checking. We design the environment so the right decision requires no willpower.
The rational school and the behavioural school were arguing for decades.
Fama said markets are rational. Kahneman and Thaler proved people are not. That debate famously raged at the University of Chicago for thirty years. The Great Investments Programme doesn't pick a side — it takes the most useful conclusion from each and combines them into one practical discipline.
Respect the market's efficiency
Don't try to out-trade an efficient market on short timeframes. Build on the durable, evidence-based factors that actually explain long-run returns, and then hold with conviction. This is why GIP is low-frequency by design.
Design around human irrationality
Accept that your instincts will betray you in a crisis. So remove the instinct from the decision: pre-set rules, pre-set exits, pre-set cadence. The behavioural research tells us exactly which mistakes to expect — so we build the system to prevent them.
A disciplined long-term engine
Efficient-market rigour in what you buy. Behavioural discipline in how you hold it. One without the other fails. Together, they form a methodology that is academically grounded rather than improvised.
You stop being your own worst enemy
The biggest single improvement most private investors can make is not a better stock tip — it is no longer panic-selling at the bottom. The Oxford research is what makes that improvement systematic rather than aspirational.
Why most investors underperform their own investments.
It sounds impossible, but it is one of the most robust findings in finance: the average investor earns meaningfully less than the very funds they invest in. The fund goes up; the investor, who buys after the rises and sells after the falls, captures only a fraction of it.
Researchers call this the behaviour gap — the difference between investment returns and investor returns. It is caused almost entirely by the predictable psychological errors Kahneman, Thaler and others documented. Closing that gap is worth more to most people than any single stock pick.
The Great Investments Programme is, at its heart, a machine for closing the behaviour gap. The stock selection matters — but the behavioural scaffolding is what lets you actually keep the returns.
The six biases the programme is built to neutralise.
Each of these is a documented, named cognitive bias from the academic literature. Each one quietly costs private investors money every year. And each one has a specific structural countermeasure built into the Great Investments Programme.
Panic-selling the bottom
Fear of further loss makes investors sell at exactly the wrong moment. Countermeasure: exits defined in advance, in calm conditions, before emotion takes over.
Clinging to losers
We overvalue what we already own and refuse to let it go. Countermeasure: rules-based review that treats every holding as if you were deciding to buy it fresh today.
Chasing the crowd
Buying what everyone else is buying, at the top. Countermeasure: a screening process driven by data and durable factors, not by headlines or hype.
Over-trading
Believing you can time the market leads to costly churn. Countermeasure: Low-Frequency Investing by design — fewer, better, longer-held decisions.
Extrapolating the last move
Assuming whatever just happened will continue. Countermeasure: long-horizon factor analysis that weighs decades of evidence over last week's price action.
Treating money irrationally
Treating "house money" or "portfolio money" by different rules. Countermeasure: a single, consistent framework applied to the whole portfolio, every month.
You can have the best stock screen in the world. But if you sell it in a panic three months later, the screen was never the problem. The Oxford research is what fixes the part of investing that actually loses people money — themselves.
