The Buffett Indicator breaks through the all-time high warning level, reaffirming the importance of a changing era

Legendary investor Warren Buffett has officially stepped down as CEO of Berkshire Hathaway. The transfer of control that spans over 60 years is not just a generational change but could mark a turning point for the entire financial market. Of particular note is the fact that this retirement timing coincides with the Berkshire Hathaway Indicator reaching its all-time high.

Berkshire Hathaway Indicator rises to 221.4%, a 22% surge since April—historic warning sign?

The Berkshire Hathaway Indicator has now reached 221.4%, recording a sharp 22% increase since April 30. This is the largest rise since the data collection began in 1970. Calculated by dividing the Wilshire 5000 Index by the US GDP, this indicator suggests that higher values indicate an overheated stock market.

Market participants are questioning how sustainable the market supported by the AI boom through 2025 can be. The historic high of the Berkshire Hathaway Indicator serves as a warning signal that future market adjustments cannot be ignored.

Greg Abel officially takes the helm; Berkshire’s DNA remains unchanged

Greg Abel officially assumed the CEO position on Wednesday. He is the successor Warren has designated for many years, and he is expected to maintain Berkshire’s playbook without any modifications. Howard Buffett (Warren’s son) stated last year that the core of the corporate culture will continue to be preserved: “Do what you say you will do, and do it when you say you will. Be honest. If you make a mistake, take responsibility.”

Greg’s style remains traditional—acquiring strong companies, not swayed by market panic, and maintaining silence without solid numbers. The continuation of Warren’s classic investment philosophy guarantees Berkshire’s stability.

Warren’s astonishing 6.5-year returns—why ordinary investors cannot follow

If you had invested $1 million in the S&P 500 from 1957 to 2007, it would have grown to $166 million. However, Warren’s own investment of the same amount reached $81 billion. This overwhelming difference is a testament to his investment insight and patience.

Furthermore, adding 18 years until 2025, Warren’s portfolio has grown to $428 billion. Most CEOs of technology companies were already born when his career began. While maintaining investments in giants like Apple, Amazon, and Alphabet, his achievements—building a foundation during the pre-internet era—are impossible for subsequent investors to replicate.

Warren’s dilemma: riding the wave of AI while rejecting cryptocurrencies

Warren was not just a bystander in 2025. His portfolio remains filled with technology-related stocks. He did not fight the AI-driven market but quietly rode the wave to maximize profits. Meanwhile, his stance on cryptocurrencies remains unchanged—his open letter to Bitcoin has gone unanswered to this day.

Now that he has departed, a question arises across the entire financial market: Is there truly anyone who can watch the market from Warren’s perspective and make sound judgments? Almost everyone in the industry has treated his decisions as gospel. The void left by a figure compared to Einstein, Edison, and Mozart is not easily filled.

Loss of certainty: new challenges facing the market

The end of the Warren Buffett era signifies not just a leadership change but the loss of a market compass. The future developments are uncertain. With the Berkshire Hathaway Indicator at a historic high, Greg’s new leadership, and the uncertain outlook of the AI boom converging, investors are increasingly compelled to exercise caution.
