CAPM Keeps You Average. Value Investing Makes You Wealthy.
Most investors unknowingly handicap their potential by relying on models designed to reward conformity. The Capital Asset Pricing Model (CAPM) may work well if your goal is to match the market, but it does little for those aiming to outperform it. In fact, it’s built on assumptions that collapse under real-world scrutiny. Meanwhile, value investors who understand that markets are often wrong, not just temporarily, but dramatically, find themselves stepping into profit while the crowd waits for consensus. Just today, three of our undervalued stocks surged more than 5%, and one rocketed close to 20%, proving again that inefficiencies are real and exploitable.
Why CAPM Was Never Designed to Help You Beat the Market
Let’s start with what CAPM assumes and why that’s a problem for anyone seeking real alpha.
CAPM presumes all investors are rational, markets are efficient, and information is instantly priced in. This model defines expected returns as a function of beta, how much a stock moves relative to the market, and the risk-free rate. But here’s the catch: it doesn’t account for behavioral biases, institutional constraints, or information asymmetries. It assumes investors agree on a single estimate of risk and return. In other words, it assumes away the opportunity to outperform.
If your strategy is to buy what everyone else is buying at the same time, CAPM is your tool. But for the independent-minded investor, it’s a straightjacket.
Real-World Market Mispricings: The Gaping Holes in “Efficiency”
Markets misprice stocks all the time. And they don’t just miss by a little, they miss by a mile.
This is specifically true for small cap stocks.
We’ve seen this time and again in our own portfolios. Just today, one of our positions jumped nearly 20% on a single catalyst. These are companies that screened as deeply undervalued according to our proprietary models, but were ignored or overlooked by the broader market. The surge came not because the fundamentals suddenly changed, but because the market finally woke up.
In another example, we have seen small-cap stocks trading at less than its net-net working capital rally after a strategic buyer announced interest. The value was always there, CAPM just couldn’t see it because it wasn’t “risky” enough in a beta sense to warrant attention.
These inefficiencies persist because of institutional blind spots, forced selling, index exclusions, and investor psychology. And they create massive upside for those willing to step away from the herd.
How Herd Mentality Becomes Self-Reinforcing
One of CAPM’s greatest flaws is that it reinforces groupthink.
Since institutional capital is measured against benchmarks, fund managers are incentivized to stay close to the index. Too much deviation, even if it’s correct, can get you fired. As a result, most asset managers are driven not by optimal returns but by job security. The result is a market that values consensus over insight.
This dynamic perpetuates mispricings in areas where there is no analyst coverage, where stocks don’t have the liquidity institutions require, or where earnings are lumpy but long-term value is real.
And that’s exactly where we operate.
Why Value Investors Need to Think Like Business Owners, Not Quants
The reason CAPM fails in practice is that it views stocks as mere blips on a risk-return graph. We view stocks as ownership stakes in real businesses.
We are prepared to assume control of the company to realize the full value in its equity.
That distinction matters. When you buy a business for less than its intrinsic worth, you don’t need a model to validate your decision. You just need time and patience.
Our investment process doesn’t rely on beta. It relies on margin of safety, cash flow analysis, and rational capital allocation. And when the market finally recognizes the value we saw all along, the payoff is outsized.
We don’t seek to minimize variance, we seek to maximize long-term compounded wealth. That’s a very different goal than what CAPM is designed to do.
Case in Point: Our Portfolio Is Beating the Market Because We Ignore CAPM
Today’s 5%+ moves across three of our holdings are not an accident. They are a direct result of an investing process that begins with this core belief: markets are not efficient, and that is a gift.
We identified these stocks through deep fundamental research, not some risk-adjusted expected return model. In fact, most of these stocks had low beta and would’ve been dismissed by CAPM as offering insufficient return for the risk.
And yet, here we are, sitting on gains while the market catches up.
Our members see this every week. It’s why they joined in the first place.
Break Free from the Herd and Build Real Wealth
CAPM is perfect if your goal is to remain average. But if you’re here to grow your wealth and outperform the crowd, you’ll need to let go of the fantasy of efficient markets.
Markets are inefficient because people are emotional, institutions are constrained, and most investors are too timid to act before consensus forms. But you don’t have to be. The opportunities are real. And if you have the process, and the patience, you can capture them.
