Berkshire Hathaway B Stock: Buy, Sell, or Hold

If you’ve ever wondered whether Warren Buffett’s Berkshire Hathaway is still a worthy investment, you’re not alone — the Class B shares (BRK.B) have turned $1,000 into over $11,000 since 2004, but recent years tell a different story.

Current Price: $483.68 · P/E Ratio: 14.40 · Market Cap: $1.04 trillion · Price/Book: 1.45 · Dividend Yield: 0.02% · 5-Year Return: +68.12%

Six key facts, one pattern: Berkshire’s valuation suggests a discount versus the broader market, but its relative performance has softened in the tech-led decade.

Is Berkshire Hathaway B stock a good stock to buy?

What are the risks?

• Concentration risk: Berkshire’s top holdings (Apple, Bank of America, Coca-Cola) mean the stock can swing with a few names (Discipline Funds (investment analysis blog)).
• Key‑man risk: Warren Buffett’s eventual departure introduces uncertainty about future capital allocation.
• Underperformance vs S&P 500 over the last decade: BRK.B’s 10‑year annualized return was about 12.65% vs SPY’s 14.72% (PortfoliosLab (stock comparison tool)).

What is the growth potential?

• Berkshire’s massive cash pile (over $300 billion) gives it firepower for opportunistic acquisitions and stock buybacks.
• Lower volatility (3.47% for BRK.B vs 5.58% for SPY) appeals to risk‑averse investors (PortfoliosLab).
• Insurance float and investment income provide a steady earnings base independent of market conditions.

The trade-off: value investors accept lower recent returns in exchange for downside protection and a durable business model.

What happened if I invested $1000 into BRK 20 years ago?

What would $1000 be worth today?

A $1,000 investment in BRK.B in mid‑2004, with dividends reinvested, would have grown to roughly $11,000 by today — a CAGR of about 12% based on historical returns (Slickcharts (historical return tracker)). That’s nearly twice the rate of inflation over the same period.

How does that compare to inflation?

Inflation averaged about 2.5% per year over those two decades, meaning the real (inflation‑adjusted) gain was closer to $8,000 in today’s purchasing power. The same $1,000 in the S&P 500 (SPY) would have grown to about $10,300 after inflation, slightly less than BRK.B. So Buffett’s legendary run from 1980–2000 still paid off for long‑term holders — but the edge has narrowed sharply.

The implication: timing matters — past outperformance does not guarantee future edge.

What is the 10 year return on BRK.B stock price?

What is the 10-year CAGR?

Over the past decade, BRK.B’s annualized total return (price appreciation plus reinvested dividends) stands at about 9.5% per year, while the S&P 500 (SPY) delivered roughly 13% (PortfoliosLab (stock comparison tool)). That translates to a cumulative 10‑year return of about 150% for BRK.B versus 250% for the S&P 500.

How does it compare to the S&P 500 10-year return?

The S&P 500’s lead is driven largely by mega‑cap tech stocks (Apple, Microsoft, Nvidia) that Berkshire has been underweight. Berkshire’s portfolio has historically favored consumer staples, financials, and energy — sectors that performed well in the early 2000s but have lagged in the 2010‑2020 tech era. As a result, the margin between the two has shrunk to about 1% per year (Discipline Funds (investment analysis blog)).

The pattern: low correlation adds diversification benefits for a portfolio, not a guarantee of future returns.

Is BRKb better than s&p 500?

What are the key differences?

• Concentration: BRK.B is a single stock and a conglomerate, while the S&P 500 holds 500 companies across all sectors.
• Volatility: BRK.B has lower volatility (3.47% monthly) than the S&P 500 (5.58%) (PortfoliosLab).
• Dividends: BRK.B yields only 0.02%, while the S&P 500 yields about 1.3%.
• Management: BRK.B is actively managed by Warren Buffett and his team; the S&P 500 is a passive index.

Which has performed better?

The answer depends on the time horizon. Over the past 20 years, BRK.B edged out the S&P 500 (CAGR ~12% vs ~11%). Over the past 10 years, the S&P 500 has clearly outperformed. Over the past year, BRK.B has actually declined about 3.77% while the S&P 500 gained 6.67% (as of mid‑2026) (PortfoliosLab).

Five metrics, one takeaway: BRK.B offers lower risk but also lower growth in the current environment.

Is brk b overvalued?

What metrics suggest overvaluation?

• Alpha Spread’s intrinsic value estimate for BRK.B is $395.56, while the current price is $483.68 — implying an overvaluation of about 18% (Alpha Spread).
• Price/Book ratio of 1.45 is above Berkshire’s historical average of about 1.2–1.3, signaling that the market is pricing in a premium for the brand.

What metrics suggest undervaluation?

• P/E ratio of 14.40 is well below the S&P 500’s average of 20+ and below Berkshire’s own 10‑year average P/E of 16.
• Berkshire’s cash holdings (over $300 billion) and insurance float provide a large intrinsic value buffer that standard valuation models may not fully capture.
• Warren Buffett has been consistently buying back shares, signaling management’s belief that the stock is undervalued at current levels.

The catch: valuation models conflict, making the stock a classic value versus growth debate.

“Berkshire carries more concentration and key-man risk than a diversified S&P 500 holding.”

What this means: investors must decide whether the margin of safety compensates for the concentration and leadership risk.

Summary: What this means for your portfolio

Berkshire Hathaway B stock remains a powerful compounding machine with a margin of safety that many growth stocks lack. But the era of massive outperformance is likely behind it — the S&P 500 has been the better growth play for the past decade, and the divergence may continue in a tech‑led bull market. For the long‑term investor in the United States, the choice is clear: if you want lower volatility and a proven track record, BRK.B remains a solid anchor; if you seek growth to keep pace with the market, the S&P 500 has been hard to beat.
