How can an ordinary outsider investor possibly outsmart a giant like Warren Buffett? I mean , that sounds like a complete myth, doesn't it? A true story of David vs. Goliath playing out on Wall Street. You might think that financial titans have all the cards in their hands, but the crazy truth is that being a small investor is an incredible hidden superpower.
Welcome to this explanatory video. Today we will analyze the genius of Joel Greenblatt's famous technique "The Big Secret for the Small Investor ". And I'm really excited to share it with you , as we look at a mathematical and psychological blueprint you can use to turn your small portfolio into your biggest advantage.
Well, let's dive right into our five-part plan. We'll look at the game where the giants can't, master valuation for the lazy, expose indexing flaws, build your personal value index, and ultimately conquer the Odyssey strategy. So, part one: playing where the giants can't—the " bronze league" advantage.
How to beat Michael Jordan in his prime? Well, it's simple. You don't play basketball with him. And that's exactly what Joel Greenblatt advises his students at Columbia University to beat Wall Street. You see, Warren Buffett is forced to play in what we'll call the " diamond league." Because Berkshire Hathaway manages huge sums of money, it is literally forced to invest in giant companies like Apple or Nvidia.
He has to operate with billions to somehow influence the outcome. But you, as a small investor, can play in the " bronze league." You can choose nimble companies with a market capitalization of up to $1 billion. And the most important thing to remember here: 15% returns are 15% returns, regardless of whether you get them from a trillion-dollar tech giant or a small manufacturing company.
To get an idea of the scale of this opportunity, look at this number: 826. That's the number of companies with a capitalization of less than a billion dollars in Sweden alone. Think about it. When you drop below the one billion dollar threshold, where Wall Street whales simply can't invest significantly, you find yourself on a vast and free playing field.
Essentially, you get significantly more opportunities, much less competition, and a significant structural advantage over the giants. Well, let's move on to the second part: an assessment for the lazy. The main thing here is to prioritize relative attractiveness, not overly complex mathematical calculations.
You might think you need a PhD in finance or crazy financial modeling to find such great small companies. Let's completely debunk this frightening myth right now. It all starts with Benjamin Graham's brilliant concept. He is the father of value investing and, in fact, Warren Buffett's mentor. It is called " safety margin".
In simple terms, it is the difference between the price you pay and the real value you receive. And why is this so important? Well, if you insist on a large margin of safety, frankly , a lot of adversity can happen in the business before you sell it, and you will still come out on top . It acts as a giant financial shock absorber for your money.
But how do you actually find this value? Traditional Wall Street analysts use overly complex discounted cash flow models. Essentially, they are trying to predict a company's profits 30 years into the future, which, frankly , is completely absurd. Most highly paid analysts can barely accurately predict a company's earnings for the next quarter, let alone three decades.
So, since virtually no one can do this with real accuracy, Greenblatt suggests we abandon this complex approach altogether. Instead, we will use the assessment for the "lazy". Step one: simply exceed your opportunity cost. Look, if you can get about 4-6% on the nearly risk-free 10- year US Treasury bond, then any stock you buy has to confidently outperform that to be worth your time.
Step two: Focus on relative attractiveness. Actually, think about it this way. I don't know exactly how many hits Captain America can take before he falls, but I do know that he can take significantly more than Loki. You see, you don't need to know the exact value of a company down to the last penny, just determine whether it is relatively cheaper and more attractive than its competitors.
So, part three: the disadvantage of indexing , the systemic trap of weighting by market capitalization. You've probably been told a million times that you can't beat the market , so just buy a standard index fund and forget about it. But take Disney, for example. When its stock price fell and it became an incredibly lucrative proposition, standard market-cap- weighted index funds systematically bought less of it.
Conversely, when Disney was at its absolute peak value, the same index funds were buying 50% more of it. Because they weigh purchases based on market size, they are literally forced into a vicious cycle of buying high and selling low. This is a real trap. As during the dot-com bubble, capitalization-weighted funds were simply flooded with wildly overvalued IT companies.
Or after the September 11 attacks, they avoided deep discount airline promotions entirely. They simply blindly follow the bipolar swings of market sentiment. So, what's the simple solution to avoid this madness? Balanced portfolio investment. If you are building a balanced portfolio, of course, you may accidentally buy an overvalued stock, but your mistakes will be purely random, not a systematic mathematical guarantee of overpayment.
And the data fully confirms this. A large-scale study of 3,300 stocks over a 25-year period found that abandoning traditional capitalization in favor of fundamentals actually outperformed traditional index funds by 2.7%–4.5% annually . Over the course of an investor's lifetime, these small percentage points turn into substantial amounts of money.
This really gives the underdog a serious advantage. Which brings us to part four: your personal value index—cheap and great. So how can we use all this data? First, determining whether a stock is cheap is not at all difficult. You simply compare its cost with the profit. This is your price- to-earnings ratio, or P/E ratio.
For example, if Apple's P /E is 33 and Google's is 18, then Google is cheaper. It's really that simple. But there is a nuance here. We don't just want cheap, right ? We want a great business. And Joel Greenblatt's " magic formula" solves this perfectly. First, you rank stocks by their cheapness, meaning you look for a low P/E ratio.
You then independently rank the same stocks by how efficiently they use capital to generate profits, which means high return on capital. Then you simply combine these two rankings and buy the companies with the best combined performance. You are effectively creating your own value index. And this perfectly illustrates why this approach is a game changer.
When Greenblatt tested this "cheap and great" ranking system on historical data from 1990 to 2010, the results were stunning. A $10,000 investment in the standard S&P 500 has grown to about $43,300. The Russell 1000 rose to $45,800. But that same $10,000 invested in this individual value index turned into $135,000.
We are talking about 13.9% per year, which completely exceeds standard indicators . Without a doubt. But listen, knowing math is only half the battle. Now we need to face the final boss. Part Five: Odysseus' strategy, fighting psychological biases. Let 's be honest, as humans, we are evolutionarily predisposed to be terrible investors.
Think about it. When our ancestors lived in the savannah, it was perfectly logical to instantly flee in panic at the rustling of bushes, because, after all, it could be a lion. You fear loss—you act quickly. But if we panic and run at the first sign of danger in the stock market, well , we're just another lemming on the way to slaughter.
And the craziest thing is that even top professional fund managers are suffering from this. Almost half of the most successful managers in the 2000s spent at least one three-year period performing in the absolute bottom decile. So, if the so- called professionals panic and lose their long-term vision, what chance do we have?
You must build a system that will save you from yourself. Like the Greek hero Odysseus, right? He tied himself to the mast of his ship to keep it from heading towards the rocks when he heard the hypnotic singing of sirens. You need to do the same with your money. First, commit to investing 40 to 80% of your money in stocks.
Second, only rebalance your portfolio once a year. Choose a date and stick to it. Third, if you feel you absolutely need to change your overall asset allocation, you are allowed to change it by a maximum of 10% in either direction per year. This gives you some room to maneuver. And finally, and I can't stress this enough : don't log into your brokerage account more than once a month .
Just ignore the daily noise. And that brings us right back to the main point of this explainer video . The biggest secret of a small investor? It's not a complex algorithm, it's not a powerful supercomputer, and it's certainly not insider connections on Wall Street. Your greatest asset is simply your ability to maintain a long-term perspective in a world that is rapidly losing its ability to focus.
You see, professional managers are constantly under pressure from clients demanding quarterly returns, which forces them to be short-sighted. But you have no customers. You should only report to yourself. So I'll leave you with this last critical question. The mathematics of how to actually beat the market is right in front of you now.
You play in the small-cap "bronze league," demand a relative margin of safety, avoid the systemic trap of standard index funds, and buy cheap and great companies. But none of this, and I mean literally nothing, works without patience. So will you have the discipline to tie yourself to the mast, or will you just follow the lemmings straight into the abyss?
Thank you very much for joining me in this explanation. I sincerely hope this has given you the tools to completely rethink your preference.
