Berkshire Hathaway is much more than an investment portfolio.

The company generated about $371 billion in revenue across insurance, manufacturing, transportation, energy, retail and distribution in 2025. Insurance was the largest piece, but businesses like BNSF, Pilot, McLane and Berkshire Hathaway Energy also contributed billions.

That mix of businesses is one reason $BRK.B is unique—you’re essentially getting exposure to several parts of the economy under one company.

Nvidia’s rise shows just how much investor expectations around AI have reshaped the market.

At the figures shown here, NVDA is valued around $1 trillion more than $AAPL. To put that gap into perspective, it’s roughly the size of JPMorgan Chase’s entire market value.

Market cap isn’t the same as revenue or profit—it represents what investors believe a company is worth based on its current business and future expectations.

The biggest long-term winners aren’t always the companies investors expect.

Since August 2016, Nvidia leads this group with a massive 14,000%+ return, followed by Bitcoin, Sterling Infrastructure, AMD and Comfort Systems USA.

The lesson isn’t to chase yesterday’s winners. It’s that holding exceptional assets through years of volatility can produce results that are difficult to imagine at the beginning.

Time, patience and business growth can be powerful wealth-building tools.

The next wave of investing opportunities could come from industries reshaping how we live, work and build.

AI, cloud computing and semiconductors remain major growth themes, but areas like nuclear energy, cybersecurity, automation, electrification and space are also attracting attention.

Companies like NVDA, MSFT, AMZN, AVGO, LLY, RKLB and CRWD give investors exposure to some of these trends.

The key is not chasing every hot sector—it’s finding strong businesses positioned to benefit from long-term growth.

The past five years have rewarded investors who had exposure to semiconductors and technology.

SMH leads this group with a 40%+ annualized return, while XLK and VGT also delivered strong performance. Broader funds like VOO, VTI and ITOT produced lower returns but offer exposure across much more of the U.S. market.

Higher past returns often come with more concentration and risk. Don’t choose an ETF based on performance alone—understand what it owns and how it fits your strategy.

Some of America’s biggest brands have deep roots across the country.

From Amazon and Microsoft in Washington to Coca-Cola in Georgia, Walmart in Arkansas and FedEx in Tennessee, major companies have grown from local businesses into brands recognized around the world.

For investors, a company’s headquarters is only the starting point. The strongest businesses can expand far beyond their home state and build customers, revenue and influence worldwide.

Li Lu’s portfolio is a strong example of high-conviction investing.

Nearly half of Himalaya Capital’s reported portfolio is in GOOG, while PDD and BRK.B make up another large portion. Together, those three positions represent roughly 85% of the portfolio.

The lesson: some successful investors prefer owning a small number of businesses they understand deeply instead of spreading money across dozens of stocks. The tradeoff is that concentration can increase both potential returns and risk.

Some of America’s biggest businesses aren’t publicly traded.

Cargill leads the list with roughly $154B in annual revenue, while Koch, Publix, Mars and H-E-B also generate tens of billions each year.

Unlike public companies, private companies don’t sell shares on the stock market and generally face fewer public reporting requirements. But that doesn’t stop them from becoming massive businesses.

It’s a good reminder that company size and success aren’t limited to the stocks we can buy.

Bill Ackman is known for running a concentrated portfolio rather than owning hundreds of stocks.

His Pershing Square portfolio includes major positions in UBER, BN, MSFT, AMZN and $HHH, along with companies like META, V, MA and NFLX.

The lesson: diversification doesn’t always mean owning dozens of investments. Some investors prefer fewer high-conviction positions—but concentration also means each investment can have a much bigger impact on your portfolio.

JD Vance’s portfolio takes a mostly ETF-based approach rather than relying heavily on individual stocks.

Large positions in $QQQ, $SPY and $DIA provide exposure to different parts of the U.S. stock market, while smaller allocations to gold, Bitcoin, long-term Treasury bonds and oil add exposure beyond stocks.

The takeaway: a portfolio can combine growth, broad-market exposure and alternative assets instead of depending on one investment strategy.
