A business can dominate today’s headlines and still lose its edge before the next decade ends. Finding the best stocks to buy for the next 20 years means examining which companies can adapt, protect their profits, and keep serving customers as industries change. Artificial intelligence and cloud computing offer substantial opportunities, but healthcare, financial services, consumer spending, and energy infrastructure also belong in the conversation about long-term stocks.
The Digital Economy Still Needs Physical Infrastructure
Behind every AI application sits a network of chips, servers, cooling systems, and electricity connections. The International Energy Agency’s 2025 outlook projected that global data center electricity consumption would more than double to around 945 terawatt-hours by 2030, roughly matching Japan’s electricity use at the time. For investors researching stocks for long-term growth, that links the technology boom to opportunities in power generation and supporting infrastructure. www.iea.org
Healthcare follows another powerful trend. The World Health Organization projects that one in six people worldwide will be at least 60 years old by 2030, suggesting greater needs for treatment, diagnostics, and care. Meanwhile, businesses providing everyday goods, waste collection, and financial services serve recurring needs that can endure through successive technology cycles. The investment challenge is identifying which providers can turn that demand into sustainable earnings. www.who.int
Twenty Years Gives Compounding Room to Work
The mathematics explains the appeal of buy-and-hold stocks. At a hypothetical annual return of 8%, an investment would grow to approximately 4.7 times its starting value over 20 years, before taxes and fees. Real markets follow a bumpier path, and holding an investment longer cannot rescue a deteriorating business.
Strong long-term candidates need competitive advantages, sound finances, and opportunities to reinvest cash profitably. The purchase price also matters because even impressive growth can disappoint investors when expectations are already stretched. A decades-long horizon rewards patience most effectively when it comes with careful valuation and regular checks that the business still deserves its place in the portfolio.
Berkshire Hathaway Inc. (NYSE:BRK.B) ranks 5th in our list of 10 Best Stocks to Buy for the Next 20 Years. Click HERE to find out other stocks on the list.
Berkshire Hathaway Inc. (NYSE:BRK.B)
Number of Hedge Fund Holders: 135 | Market Capitalization: $1.14 trillion
Diversified Businesses Put Capital Allocation at the Center
Berkshire Hathaway Inc. (NYSE: BRK.B) offers exposure to insurance, rail transportation, utilities, manufacturing, services, retail, and publicly traded investments within one corporate structure. That breadth gives it several sources of earnings, although it does not eliminate exposure to economic downturns.
Insurance is central to the financial model. Premiums arrive before many claims are settled, creating funds known as insurance float that can be invested while obligations remain outstanding. Float can be valuable, but its cost depends on underwriting performance. Poorly priced policies and unexpectedly large claims can erode the benefit.
With Greg Abel serving as chief executive in 2026, the long-term investment question centers on the continuity of operating discipline and capital allocation. Berkshire Hathaway Inc. (NYSE: BRK.B) must decide when to expand subsidiaries, acquire businesses, purchase securities, or retain liquidity.
Its enormous size creates a practical constraint: small investments cannot move overall results very much. Catastrophe losses, utility liabilities, and weaker industrial activity also deserve attention. For investors seeking diversified long-term stocks, the case rests on resilient operating earnings and sound reinvestment decisions, with realistic expectations about how quickly a business of this scale can grow.
Ranking Rationale
Berkshire Hathaway Inc. (NYSE: BRK.B) places fifth with 135 hedge fund holders. Diversified operating businesses, insurance float, and the ability to allocate capital across industries strengthen its long-term investment case, although its size makes rapid growth increasingly difficult.
