Warren Buffett beat the S&P 500 over his 60-year tenure as CEO — and as of January 2026, Greg Abel now runs the company, with Buffett staying on as Chairman. A complete data-driven comparison to help you decide whether Berkshire deserves a place in your portfolio.
The article previously framed Berkshire's CEO succession as a future question — that transition has now happened: Greg Abel became CEO on January 1, 2026, with Warren Buffett continuing as Chairman. Q2 2026 results (reported Aug 8) showed operating earnings up 16.3% YoY to $12.98B, though GEICO-driven insurance underwriting profit fell 13%. Berkshire's cash hoard peaked at a record $397B in Q1 2026 before Abel accelerated buybacks, pulling it down to ~$344B by June 30. The equity portfolio has grown more concentrated under Abel: Apple's weight fell to ~22% (held flat this quarter after years of selling), and Alphabet is now a top-5 holding at ~9.4%. Sourced from Berkshire's SEC 10-Q and 13F filings, stockanalysis.com, CNBC, and Forbes, as of 8/8–8/16/26.
From 1965 to 2024, Berkshire Hathaway delivered a 19.8% compound annual gain — versus 10.2% for the S&P 500 with dividends reinvested. A single $1,000 invested in Berkshire in 1965 would have grown to over $40 million by 2024. The same $1,000 in the S&P 500: roughly $300,000.
The compounding machine rests on several structural advantages that most investors cannot replicate:
~$177.5B (as of June 30, 2026) of 'free' investable capital generated by collecting premiums before paying claims. This float has historically cost near-zero or even generated profit.
Buffett built this skill over 60 years as CEO; new CEO Greg Abel now controls capital deployment across public equities, private acquisitions, and buybacks, with early signs (accelerated buybacks, his first acquisition, holding the Apple stake flat) suggesting continuity of the discipline.
Berkshire has no quarterly earnings calls that require hitting analyst estimates. The company's culture of thinking in decades, not quarters, predates Abel and appears intact under him — allowing management to buy when others are panicking.
Unlike most financial companies, Berkshire uses debt conservatively. The fortress balance sheet (~$344B cash, down from a record $397B in Q1 2026 as Abel deploys more into buybacks) means Berkshire survives every crisis and often thrives by buying distressed assets.
Berkshire is best understood as four distinct businesses bundled under one holding company structure. Understanding all four is essential to valuing the stock.
Berkshire's insurance subsidiaries collect ~$80B in premiums annually and pay claims over time. The gap — the 'float' — creates ~$177.5B of investable capital (as of June 30, 2026) that Berkshire effectively borrows at near-zero or negative cost. This is Berkshire's most powerful structural advantage. GEICO alone insures ~15 million vehicles and is the second-largest US auto insurer. Underwriting profit dipped 13% in Q2 2026 on GEICO-driven claims pressure, a metric worth watching under the new CEO.
BNSF Railroad — the second-largest US freight railroad by revenue — alone generates $5B+ in annual earnings. Berkshire Hathaway Energy (BHE) operates utilities and pipelines across 11 states. Precision Castparts manufactures aerospace components. These businesses generate steady, recession-resistant cash flows that don't require stock market exposure to compound. Combined, the operating businesses earn ~$20B+ per year.
Berkshire holds a concentrated public stock portfolio of roughly $299B (Q2 2026 13F). Apple alone is ~22% of the portfolio — Abel held the position flat this quarter, halting Buffett's multi-year selling trend. Unlike a mutual fund, Berkshire holds stocks indefinitely — Coca-Cola since 1988, American Express since 1994. Alphabet is a newer top-5 addition at ~9.4%. The portfolio generates several billion dollars in annual dividends which Berkshire reinvests. Berkshire's cost basis on Apple is ~$31/share — a position still worth several multiples of the purchase price.
As of June 30, 2026, Berkshire holds approximately $344B in cash and short-term government securities — down from a record $397B at Q1 2026 as new CEO Greg Abel accelerated share buybacks (~$4.8B in H1 2026, mostly in Q2). It remains the world's largest 'dry powder' position. If markets crash 40–50%, Berkshire can deploy hundreds of billions at distressed prices, as it did in 2008–2009.
Annual returns are approximate total returns. Berkshire does not pay dividends — returns are pure price appreciation. S&P 500 figures include dividend reinvestment.
| Period | BRK/B Ann. Return | SPY Ann. Return | Winner | Note |
|---|---|---|---|---|
| 1 Year (2025) | 18.4% | 23.1% | SPY | Tech mega-caps drove S&P 500; Berkshire's Apple stake helped but diversification limited upside |
| 3 Years (2023–25) | 16.2% | 12.1% | BRK | Post-rate-rise environment favored Berkshire's insurance and banking holdings |
| 5 Years (2021–25) | 14.8% | 15.3% | SPY | Near parity; Magnificent 7 concentration in S&P 500 a tailwind |
| 10 Years (2016–25) | 13.9% | 13.2% | BRK | Modest BRK edge; operating businesses compound alongside equity portfolio |
| 20 Years (2006–25) | 11.8% | 10.4% | BRK | Longer compounding period favors BRK's operating earnings quality |
| 30 Years (1996–25) | 14.2% | 10.8% | BRK | Buffett's compounding machine at its most pronounced over full market cycles |
Takeaway: Over full market cycles, Berkshire and the S&P 500 deliver roughly similar annualized returns with BRK holding a modest edge at 20–30 year horizons. BRK tends to outperform in down markets and underperform in the strongest tech/growth bull runs.
What was a looming question for years is now a completed fact: Greg Abel became Berkshire's CEO on January 1, 2026, formalized by a unanimous board vote after Buffett announced the move at the May 2025 annual meeting. Buffett, who turned 95 in August 2026, remains Chairman and reportedly still comes into the office regularly, but Abel now controls capital allocation. Seven months in, here's how the early evidence reads.
Berkshire has two share classes. BRK/A is the original share, trading around $700,000+ each. BRK/B was created in 1996 as a more accessible version, trading at approximately 1/1500th of BRK/A.
Suitable for ultra-high-net-worth investors who value voting influence. Never trade due to extreme price.
Practical for all investors. Same economic exposure. Liquid, easily tradable, and fractional shares available.
The economic value is mathematically equivalent: 1 BRK/A = 1,500 BRK/B. The only real difference for most investors is the voting weight and the irreversibility of BRK/B. For the vast majority of retail investors, BRK/B is the correct choice.
The equity portfolio (~$299B as of the Q2 2026 13F) is concentrated in high-quality businesses built over decades, now overseen by CEO Greg Abel. Here are the top holdings with approximate portfolio weights.
Note: Percentages are approximate and based on public 13F filings. Apple's share has declined from 40%+ following partial sales in 2024. The equity portfolio does not include wholly-owned businesses.
The honest bear case for BRK/B is not about the quality of the business — it's about structural challenges that come with being a $1T company.
At $1T market cap, Berkshire needs $50B+ acquisitions to move the needle. There are very few companies at that scale available at attractive prices. The 'elephant gun' has fewer targets.
Buffett's roots in cheap, asset-heavy businesses clash with the tech-driven economy. Missing Amazon, Google, and Facebook early cost Berkshire enormous alpha. He has acknowledged this.
GEICO and the reinsurance businesses face rising claims from climate-related events: hurricanes, wildfires, floods. This could structurally increase the cost of the insurance float.
At 5% T-bill rates, ~$344B earns roughly $17B/year. But deployed into equities or operating businesses at 12–15% returns, it would earn $40–50B+. The cash hoard is both protection and drag, though Abel has been shrinking it via accelerated buybacks.
Part of Berkshire's valuation historically reflected trust in Buffett specifically. Greg Abel's Q2 2026 results (earnings up 16.3% YoY, first acquisition closed, buybacks accelerated) are encouraging but span only two quarters as CEO — not enough to fully rule out a multiple discount if a real crisis tests his judgment.
| Metric | BRK/B | VTI |
|---|---|---|
| 10yr Annualized Return (approx) | ~13.9% | ~13.4% |
| Dividend Yield | 0% (none) | ~1.3% |
| Expense Ratio | 0% (stock) | 0.03% |
| Holdings | 90+ operating + 10 top stocks | ~3,600 US companies |
| Volatility (Beta vs S&P 500) | ~0.85 (lower vol) | ~1.00 (tracks market) |
| Top Sector Concentration | Insurance, Railroads, Energy | Tech (~30%+ of index) |
| Tax Efficiency | No dividends = deferred taxes | Low turnover; ETF structure |
| Succession Risk | Moderate — new CEO Abel building track record | None — index is mechanical |
| Correlation to S&P 500 | ~0.75 (some diversification) | ~0.99 (nearly identical) |
Starting value of 100 in 2016. Approximate, for illustration only. BRK/B includes no dividend; VTI/SPY include reinvested dividends.
Berkshire Hathaway is not a normal company — it is a holding company combining a publicly traded equity portfolio with wholly-owned operating businesses. Understanding both components is essential.
Berkshire's insurance subsidiaries collect premiums upfront and pay claims later — the gap creates the "float," approximately $177.5B of investable capital that costs Berkshire near-zero because premiums collected have historically exceeded claims paid. This float is the structural moat that gives Berkshire an investment advantage no ordinary investment company can replicate.
Berkshire Hathaway is one of the most exceptional wealth compounders in financial history. Its structural advantages — insurance float, wholly-owned operating businesses, disciplined capital allocation now led by CEO Greg Abel, and a fortress balance sheet — are genuinely rare and difficult to replicate.
But the honest answer for most investors is: a simple low-cost S&P 500 index fund (VOO or VTI) remains the default superior choice for long-term wealth building. The index automatically captures every future winner, costs less, requires no trust in any single management team, and provides broader diversification.
The best approach for investors interested in both: own a core index fund position (70–90% of equity allocation) and a 5–15% BRK/B position as a quality complement. You get Berkshire's capital allocation discipline on a slice of your portfolio while Abel builds a longer public track record.
Never view BRK/B as an index fund substitute — it is a single-stock position with all the risks that entails, including leadership-transition, regulatory, and climate risks specific to its businesses.
