When you listen to Warren Buffett speak, you can always take away a few words of wisdom. In fact, if most of us had the opportunity to listen to him between 1964 and 2025, as his Berkshire Hathaway returned more than 5.5 million percent cumulatively, most of us wouldn’t be worrying about money today.
If you listened to the billionaire often enough before his retirement – as I did – his message was always deceptively simple. You just need to buy and hold sizable, growing companies with consistently strong, easy-to-understand business models.
That sounds easy, but it actually runs counter to the FOMO (fear of missing out) instinct that often grips investors. From tulip mania in the 17th century to the AI bubble in the 21st century, there have always been shiny objects that can derail investors from a disciplined investment strategy.
Investing the Buffett Way
Throughout his career, Buffett (known as The Oracle of Omaha) looked to buy great stocks when everyone else was too afraid to buy. Time and again, Buffett summarized what he looked for into four themes:
- Simple companies that are easy to understand
- Companies with predictable and proven earnings
- Companies that can be bought at a reasonable price
- Companies with “economic moat,” or a unique advantage over their competition.
Here’s a quote from the Oracle himself:
“I look for companies that have a business we understand, favorable long-term economics, able and trustworthy management and a sensible price tag. We like to buy the whole business or, if management is our partner, at least 80%. When control-type purchases of quality aren’t available, though, we are also happy to simply buy small portions of great businesses by way of stock market purchases. It’s better to have a part interest in the Hope Diamond than to own all of a rhinestone,” he noted.
Here is more detail on each of these themes for spotting opportunity.
No. 1 – Look For Simple Businesses that You Understand
While not easily quantifiable, an investor must fully understand a business before investing in it. If you have a problem explaining it to yourself in simple terms that even a child can understand, or if it’s just too complex, you may want to avoid the investment.
As Buffett explains, “What an investor needs is the ability to correctly evaluate selected businesses.
Note the word “selected”: You don’t have to be an expert on every company, or even many. You only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital.
No. 2 – Look for Companies With Predictable and Proven Earnings
The book, The Warren Buffett Way describes this theme as follows:
“If the company has operated with consistent earnings power and if the business is simple and understandable, Buffett believes he can determine its future earnings with a high degree of certainty. If he is unable to confidently project a business’s future cash flows, he will not attempt to value the company. He’ll simply pass.“
Earnings are the key driver of stock price gains. Speculative stocks of companies that are unprofitable can pay off, but they aren’t appropriate for most investors, and certainly not for those who want to invest like Buffett.
No. 3 – Can the Stock Be Bought At a Reasonable Price?
Buffett’s goal has always been to identify stocks that can earn above-average returns and then buy them at prices below their current value. In fact, as Buffett noted in 1988, “Great investment opportunities come around when excellent companies are surrounded by unusual circumstances that cause the stock to be misappraised…”
It’s important to remember that value and price are different. It’s also critical to understand that valuations vary by sector.
No. 4 – Does the Company Have An Economic Moat?
If I handed you $1 billion, could you duplicate your favorite company? Or, if I handed you $100 billion, could you dethrone Coca-Cola (NYSE: KO), Alphabet (NASDAQ: GOOGL), or the market share that Apple (NASDAQ: AAPL) commands from its iPhone?
Notice that having a strong moat doesn’t mean that a company has no competition. It just means that these companies command a share of the market that will allow them to continue generating reliable revenue and earnings. In 2026 that list includes names such as: Coca-Cola, Harley-Davidson (NYSE: HOG), Apple, Meta Platforms (NASDAQ: META), McDonald’s (NYSE: MCD), Disney (NYSE: DIS), Alphabet, and Amazon (NASDAQ: AMZN).
To quantify how strong a company’s economic moat may be, we begin by examining its profit margins. If a moat exists, the business should be able to raise prices without losing market share. Otherwise, margins would decrease in a price war.
