Why Does Buffett’s Investing Strategy Make Sense?
These are the five main reasons why Buffett’s conservative approach has worked with investing:
1. He Has a Long-Term Horizon When Investing
“Warren Buffett's conservative investing strategy is successful primarily as a result of his long-time horizon of at least five to 10 years as opposed to much shorter time horizons for portfolio managers of mutual funds, hedge funds and other institutions,” said David Kass, a professor of finance at the University of Maryland's Robert H. Smith School of Business, who has also attended Berkshire Hathaway's annual meetings for the past 20 years.
Since portfolio managers are usually evaluated on their performance each year, they could end up focusing only on stocks that have been doing well recently. Warren Buffett, as the chairman and former CEO of Berkshire Hathaway, isn’t at risk of losing his job for short-term underperformance, so he can look into companies that appear to be undervalued but may take several years to realize their potential.
2. He Conducts Extensive Research Before Investing
“A second major explanation for Buffett's outperformance over time results from his predilection to make very few purchases and to thoroughly research each one,” said Kass.
While portfolio managers generally have very short holding periods with significant turnover, there’s little turnover in Berkshire Hathaway's portfolio because Buffett spends extensive time researching companies.
3. He Only Invests in What He Knows
Kass said that Buffett will only invest within his circle of competence by focusing on industries that he understands.
“As a result, he has had a lot of success in investing in the finance industry, but has avoided other industries where he has less knowledge.”
4. He Doesn’t Chase Trends
“Buffett avoids investing in enterprises involved in innovative activity,” said Robert R. Johnson, professor at Heider College of Business, Creighton University. “Instead, Buffett focuses on identifying undervalued enterprises in more staid industries.”
Johnson said that investors in innovation are often disappointed, because it’s difficult to figure out which companies are worth investing in.
“While autos had a tremendous impact on society, investors weren’t duly rewarded," he said. "The same is true for the passenger airline industry. A tremendous innovation, but a terrible investment.”
5. He Doesn’t Panic Buy or Sell
Buffett’s temperament allows him to stay calm when other investors react emotionally, allowing him to stay invested instead of making rash decisions that could hurt his portfolio.
“He does not panic and sell when the market or his investments decline, nor does he buy because the market is going up,” said Kass.
Can This Approach Still Work?
The experts agreed that this approach can still work in the modern economic era and the main takeaway was to avoid chasing trends like AI or cryptocurrency to focus on fundamentals. Johnson noted that Buffett is unlikely to be interested in investing in any artificial intelligence or Space exploration companies.
“Oftentimes, companies in nascent industries are wildly overvalued,” he said.
While Johnson believes that AI will have an enormous impact on people’s lives and that many companies will benefit from it, you may not want to invest directly in this industry just yet, since there’s still so much hype, similar to the crypto space a few years ago.
To illustrate this point, we can look at what happened in summer of 2026 with AI-based stocks. CNBC reported how shares of Alphabet and Tesla dropped after both companies shared they were increasing spending on AI, with Alphabet losing $300 billion in market value and Tesla $200 billion in one day.
“I also don’t believe the average investor can discern which firms will win the AI sweepstakes," Johnson said. "Warren Buffett's Berkshire Hathaway earned a compounded annual return of 19.9% from 1965 through 2024[1] by investing in boring, staid enterprises like See’s Candies, Dairy Queen and Nebraska Furniture Mart. These may not be sexy companies, but they perform well.”
