Berkshire's Concentrated Portfolio Under Abel Is No Accident — It's the Strategy

Berkshire Hathaway's latest SEC filing shows its top 10 stocks hold $265 billion out of a $299 billion equity portfolio — 88 percent of everything. The headline number is designed to sound reckless. But concentration of this degree isn't Greg Abel's invention. It's how Berkshire has always been run, and it's a deliberate choice about how capital works at a scale that ordinary investors rarely see.

The more useful question for a Berkshire watcher isn't whether 88 percent is dangerous. It's what Abel has put inside those 10 positions, what he's removed, and what that tells you about the investment philosophy now steering $365 billion in cash reserves and a portfolio larger than most nations' GDP.

What's Inside the Top 10

The current lineup, from the Q2 2026 filing, reads like a map of durable cash-flow businesses with one big new addition:

Apple leads at $65.9 billion (22 percent of the portfolio), followed by American Express at $51.3 billion, Alphabet at $37.8 billion, Coca-Cola at $32.5 billion, and Bank of America at $27.5 billion. The top five alone are 72 percent.

The rest of the top 10 — Chevron, Occidental Petroleum, Chubb, Moody's, and Kraft Heinz — add another $57 billion and another 16 percentage points.

Ten names. Eighty-eight percent of the equity portfolio. The remaining 12 percent is spread across roughly 20 smaller positions including Delta Air Lines, Macy's, The New York Times, and Japan trading stakes.

The Concentration Wasn't New. The Roster Is.

Under Warren Buffett for decades, Berkshire's top holdings typically consumed 85 to 90 percent of the equity portfolio. The concentration number itself hasn't changed. What has is the composition, and the speed of change.

Abel, who became CEO on January 1, 2026, cleared out 16 positions in his first quarter alone. The exits include Amazon, Visa, and Mastercard — stakes Buffett built over years and held for their durable cash flows and dividend yields. He also sold UnitedHealth, Domino's Pizza, Pool Corp, Diageo, Lamar Advertising, and Aon. Many of these carried meaningful dividend yields. Diageo yielded nearly 4 percent; Lamar, 4 percent; Pool Corp, 2.5 percent.

Then he built the opposite. Alphabet, which yields 0.25 percent, was more than tripled in Q1, then added to again in Q2 with a $10 billion private placement — bringing the total stake to roughly $37.8 billion and third place in the portfolio. Delta Air Lines, a sector Buffett explicitly rejected six years ago during the pandemic exit from all four major carriers, now sits in the portfolio with roughly 57 million shares.

The shift isn't cosmetic. Berkshire has moved from a portfolio heavy in dividend-producing franchise businesses to one that loads more on growth with minimal yield. The old approach generated predictable income from Visa, Mastercard, and Amazon alongside Apple and Coca-Cola. The new approach generates almost no dividend income from its biggest new bet and relies on capital appreciation from AI-driven cloud growth.

What the Valuations Say

The quality question behind any concentrated bet is whether the underlying businesses justify the price paid. Berkshire's top holdings span a wide range of valuation:

Apple trades at 38 times trailing earnings. That's expensive by any definition, even for a business with its scale and brand. It's the position Abel left untouched, halting a multi-quarter selling streak that Buffett began in his final months.

Alphabet trades at 17 times trailing earnings. That's cheap for a company reporting $120 billion in quarterly revenue and 24 percent year-over-year growth. The concern isn't today's earnings — it's the capital spending. Alphabet raised its annual capex guidance to $195-$205 billion to build AI infrastructure, and it reported a cash outflow of $5.8 billion in its latest quarter — its first negative free cash flow since going public. The question for any holder is whether that spending produces returns that exceed the cost of capital.

Coca-Cola at 27 times earnings and a 2.4 percent yield is a classic Buffett hold — slow growth, reliable dividends, pricing power. Moody's at 29 times earnings and Chubb at 12 times show the range of what Berkshire considers a quality business.

The portfolio isn't uniformly cheap or uniformly expensive. That's not a flaw in concentration — it's a feature. Berkshire doesn't buy a basket of stocks at the same multiple. It identifies businesses where the price is wrong relative to the underlying economics and sizes the position accordingly.

The Cash Pile Changes Everything

You can't evaluate the portfolio without the other side of the balance sheet. Berkshire sat on $365.5 billion in cash at the end of Q2 2026, down from a record $397.4 billion at the end of Q1. That means Abel deployed roughly $32 billion in a single quarter — on buybacks ($4.5 billion), the Taylor Morrison acquisition ($6.8 billion), the Alphabet private placement ($10 billion), and a broad range of other equity purchases that swung Berkshire from net seller to net buyer after 14 consecutive quarters of selling.

The cash pile matters because it means the equity portfolio isn't all the chips on the table. Berkshire's total assets are roughly $1.2 trillion. The $299 billion in public equities is about 25 percent of that. The rest is cash, wholly-owned operating businesses (BNSF, Berkshire Hathaway Energy, GEICO, Dairy Queen, and dozens more), and private stakes.

This changes the risk calculation. A 10 percent drop in the equity portfolio cuts Berkshire's total assets by roughly 2.5 percent. The insurance float, the operating cash flows, the cash reserves — they cushion a concentrated equity book in a way that doesn't apply to a fund or an individual portfolio.

What This Means for an Individual Investor

The obvious temptation is to replicate Berkshire's top 10 and call it a diversified portfolio. It isn't. Ten stocks is concentration, whether you're managing $1.2 trillion or $50,000. The difference is that Berkshire can absorb a catastrophic mistake in one position because of everything else it owns. An individual holding just those 10 stocks doesn't have a railroad, an insurance book, or $365 billion in Treasury bills.

The more useful takeaway from the filings is the approach to selection. Abel isn't building concentration for its own sake. He's building it around businesses where he sees a gap between price and what the underlying economics support — and he's willing to hold a large position while that gap works in his favor.

Alphabet at 17 times earnings with 24 percent revenue growth is a thesis about AI returns on massive capex spending. Delta is a thesis that the airline industry's best operator can earn more than its cost of capital in a recovering travel environment. Apple is a thesis that the brand and ecosystem produce cash flows that justify even expensive multiples.

Each thesis has a way to be wrong. Alphabet's capex could underperform. Delta's premium model could break in a recession. Apple's growth could slow and the multiple could compress. Concentration amplifies both the right calls and the wrong ones.

Berkshire's concentration isn't a warning about diversification or a lesson about following famous investors. It's evidence of a specific method: identify businesses with durable economics, buy when the price is wrong, size the position to the conviction, and hold while the math works. The roster under Abel is different from Buffett's. The method is the same.

The question for your own portfolio isn't whether to hold 10 stocks or 100. It's whether you can identify businesses where the price is genuinely disconnected from what they earn, have the patience to hold while the market corrects, and the discipline to accept that concentration — by definition — means some positions will underperform and the overall approach depends on getting enough of them right.
