Hot take: Studying Warren Buffet or value investing is not the flex you think it is

If you are a young investor trying to understand the next decade of markets, Buffet or Berkshire are NOT the models to study
Let me be precise about what I mean and what I don't.
The virtues Buffett embodied (conviction, discipline, the refusal to overpay) are not up for debate. What he built is one of the greatest compounding records in financial history. From 1965-2024, Berkshire returned 19.9% annually, nearly double the S&P 500's 10.4%. That record deserves genuine respect.
But there is a version of "investing like Buffett" that has become something else entirely, almost an intellectual permission slip to ignore structural change and is really just an excuse to miss what's happening.
That version deserves to be called out.
The market conditions that made Buffett a legend are not the market conditions you're operating in right now.
From 2015 - 2025, Berkshire returned 234% while the S&P 500 returned 304%. That's a decade of underperformance. Its meaningful especially when you consider what was happening in the same window. $1,000 invested in Nvidia five years ago is worth roughly $13,700 today. That's a 1,276% return. Berkshire's 5-year total return over the same stretch? About 70%.
I'm not cherry-picking. I'm making a structural point. Now zoom out to the cash pile. Berkshire ended 2025 with $373B in cash, the largest corporate cash hoard in American business history, and it grew further to $397B in Q1 2026. A reserve is now larger than the combined cash holdings of Apple, Amazon, Alphabet, and Microsoft.
How do you defend that Berkshire was a net seller of equities for ten consecutive quarters between October 2022 and March 2025, offloading more than $174B in stocks, net of purchases. They literally sold their way into the greatest AI infrastructure buildout in modern history and then parked the proceeds in T-bills. LOL
Berkshire now holds more T-bills than the Federal Reserve, ~5% of the entire US T-bill market. Think about that for a second.
The conventional defense is that Berkshire is waiting for better prices, saving the powder for a big acquisition. Fine. But it's a $1 trillion company now. The acquisition that actually moves the needle on returns at that scale basically doesn't exist. So what exactly are we waiting for?
Stay with me because here's where it gets really interesting.
There are assumptions that you hold, and there are assumptions that hold you.
The framework Buffett mastered - find a business with durable competitive moats, pricing power, and predictable cash flows; buy it at a discount; wait — was engineered for a world where the fundamental unit of value was the company. A stable entity with stable economics. Today, the fundamental unit of value is increasingly the layer. The infrastructure layer. The software layer. The data layer. And layers don't follow the same compounding logic. They compound faster, get priced earlier, and the window for building a meaningful position closes before the traditional value framework even signals a buy.
Nvidia was hiding in plain sight for years. Its GPU architecture was purpose-built for the exact workloads AI would demand. But by the time the magnitude of that was obvious in the fundamentals...revenue climbing from $10.9B to $130.5B in five years, operating income up 29x - the stock had already done most of its work. The edge was in understanding what was being built, before the income statement reflected it.
Now here's the data point that should reframe how you think about all of this. ASU professor Hendrik Bessembinder studied every US stock traded between 1926 and 2016 (over 25k+ companies)....His finding is just 4% of stocks were responsible for the entire net wealth created by the US equity market above T-bills. The other 96%? In aggregate, they matched T-bills. 4 out of every 7 individual stocks, over their entire lifetime as public companies, failed to beat a simple short-term government bond.
The US equity market looks like a great asset class because a tiny number of companies made it one.
And that concentration has only gotten more extreme. The top 10 companies in the S&P 500 now account for roughly 40% of the index's total market cap, up from about 17% a decade ago.

The top 10 generate 32% of the index's total earnings. Strip them out, and what you're left with is a long tail of businesses that, once you factor in inflation, dollar debasement, and cost of capital, have produced very little real wealth over twenty to thirty years. We don't talk about this enough.
So if the equity market's returns have always been driven by a small number of transformational companies, then a strategy built around avoiding those sectors isn't neutral. It's a bet against the only thing that actually generates alpha. You're not playing it safe. You're literally systematically avoiding the 4%.
Sitting in cash is itself a decision and it has consequences measured in what didn't compound. Berkshire earns roughly $15-20 billion a year on that pile at current T-bill yields. That sounds like a lot until you factor in the opportunity cost.
The lesson here is that every investing framework eventually meets a version of the world it wasn't built for. The best investors recognize that moment. The rest quote their heroes and wait for the market to come back to them.
Sometimes it doesn't.
