Berkshires

Over 35 years ago, Warren Buffett told investors, “When we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.” Since then, he’s bought and sold dozens of stocks for Berkshire Hathaway (BRK.A 0.55%) (BRK.B 1.06%), proving that even the Oracle of Omaha doesn’t have a perfectly clear crystal ball.

Even when Buffett has made extremely successful equity investments, he’s often had reason to sell at least some of Berkshire’s stake — either to maintain a more balanced portfolio, or sell a stock that’s become overvalued, or for any number of other reasons. Those are factors that have come to the fore recently for Buffett and his team of investment managers. Berkshire Hathaway has sold more marketable equities than it bought in each of the last 11 quarters.

Those sales include one stock that Berkshire first bought in 2008 and will go down as one of Buffett’s (and Munger’s) most successful investments of all time.

Powering massive returns for investors

In late September 2008, as the global stock market was reeling amid the Great Recession, Buffett and Munger took the opportunity to buy a 10% stake in a Chinese auto company called BYD (BYDDY -0.94%) (BYDD.F -1.20%). They gradually increased Berkshire’s stake in the business, reaching about 20% at one point. Today, the company is the largest EV manufacturer in the world, surpassing Tesla.

It was Vice Chairman Charlie Munger who brought the company to Buffett’s attention. He found CEO Wang Chuanfu’s engineering and managerial skills extremely impressive. He had developed one of the largest battery manufacturers in the world before transitioning to the automotive business in the early 2000s. With its battery expertise and other vertically integrated components made through acquisitions, BYD looked poised to do well in the nascent electric vehicle market.

Sure enough, BYD has developed a broad lineup of vehicles sold around the world. Its global sales of fully electric vehicles surpassed Tesla’s in the fourth quarter of 2023 and for the full year of 2024. It’s not just success in its home country, either. BYD’s European sales surpassed Tesla’s in April this year. Management aims to sell half of its cars outside of China by 2030. It’s worth noting BYD has yet to enter the U.S. market due to tariffs and the political environment.

It’s no surprise, then, that BYD’s stock price has soared amid its success. With the acceleration in sales over the last few years, BYD’s stock is up more than eightfold since the start of 2020.

Buffett started decreasing Berkshire’s stake in BYD starting in August 2022, after Berkshire’s initial investment had already climbed about 20-fold. At one point, Berkshire’s shares were worth $9 billion. Based on financial reports from Berkshire Hathaway subsidiary, Berkshire Hathaway Energy, the company gradually sold off shares until completely divesting its stake in the first quarter of this year.

Is the competition too much?

Buffett may have missed the absolute peak of BYD’s stock price, but shares have certainly struggled in the latter half of the year, as Chinese competitors take market share from its domestic business. BYD’s August deliveries were flat year over year, as were July’s. Not only has the intense domestic competition hurt unit sales, but it’s also hurt BYD’s margins.

But the company stands at a distinct advantage over the competition thanks to its significant vertical integration. As mentioned, BYD is one of the leading battery manufacturers in the world. That, in and of itself, is a significant advantage over other EV makers who need to source batteries from third parties. But BYD also makes many other components in its vehicles, including the motors, semiconductors, and practically everything else except the tires and glass.

That allows the business to adapt quickly and maintain better margins than its competitors. With plans for an aggressive international expansion, it’ll have to replicate its manufacturing capabilities all around the world. But management has proven quite adept at building systems and scaling them.

After the pullback in price, investors can buy shares for just 1 times sales and less than 16 times forward earnings expectations. That’s an attractive price for the leader in a growing industry, even if it’s seeing some pressure from the competition weighing on revenue growth and margins. It’s certainly a better valuation than investors could get with Tesla. While Buffett may have sold out of the stock, it might still deserve a spot in your portfolio.

It’s the end of an era on Wall Street. In less than four months, Berkshire Hathaway‘s (BRK.A -1.26%) (BRK.B -1.40%) Warren Buffett will retire from the CEO role he’s held for six decades. During his 60 years at the helm, he’s overseen a roughly 6,140,000% cumulative gain in his company’s Class A shares (BRK.A), which compares quite favorably to the roughly 43,300% total return, including dividends, delivered by the benchmark S&P 500 (^GSPC -0.32%) over the same timeline.

The Oracle of Omaha’s outperformance has made him the most-followed money manager on Wall Street, with some investors riding his coattails to substantial long-term gains.

But the other factor — aside from market-crushing returns — investors have come to appreciate about Buffett is his willingness to share his thoughts and the company traits he looks for when taking stakes in wonderful businesses. Whether it’s Berkshire’s annual shareholder letter or the company’s yearly meeting, Buffett is no stranger to offering up nuggets of wisdom.

While books have been written about Warren Buffett’s investment ideals, four ominous words from Berkshire’s latest shareholder letter perfectly encapsulate why he’s such a phenomenal investor, and explain why his recent investment activity sends a clear warning to Wall Street.

Investors are likely aware of some of the Oracle of Omaha’s core principles. For example, Buffett prefers to buy stakes in companies with sustainable competitive advantages, strong management teams, and hearty capital return programs. He also looks at investments as multiyear or multidecade commitments, with eight stocks in Berkshire’s portfolio currently considered “indefinite” holdings.

But possibly the best investment advice Buffett has ever offered, which perfectly encapsulates the promise and peril of the stock market, was penned in Berkshire Hathaway’s latest annual shareholder letter. While discussing where his company has money allocated, Buffett proclaimed, “Often, nothing looks compelling.”

At his core, Berkshire’s billionaire boss is an unwavering value investor. Though there are some unwritten “Buffett rules” that sometimes get broken, such as investing for the short-term via an arbitrage opportunity, Berkshire’s head honcho isn’t willing to buy a stock if its valuation doesn’t make sense.

At the moment, stock valuations are historically expensive. Keeping in mind that valuation is subjective, the affably dubbed “Buffett Indicator” recently hit an all-time high. This valuation measure adds up the cumulative market cap of all public companies in the U.S. and divides this figure by U.S. gross domestic product (GDP).

The market cap-to-GDP ratio, which has averaged closer to 85% of U.S. GDP when back-tested to 1970, surpassed 214% in late August. In other words, finding value has been exceedingly difficult for Buffett and his team.

Beginning in October 2022, the Oracle of Omaha began selling more stock than he was purchasing. This net-selling activity has been ongoing for 11 consecutive quarters (Oct. 1, 2022 – June 30, 2025), totaling $177.4 billion in net stock sales. All the while, Berkshire Hathaway’s cash pile, which includes cash, cash equivalents, and U.S. Treasuries, has ballooned to a near-record $344.1 billion.

Despite sitting on $344 billion in capital, Buffett prefers to be a net-seller of stocks, and isn’t even buying shares of his own company any longer. It’s as direct a warning as Wall Street will get from Berkshire’s billionaire chief.

Patience pays off handsomely in the stock market

Though Buffett’s ominous advice – “often, nothing looks compelling” — perfectly explains why he’s been more of a seller than a buyer amid a historically pricey stock market, it also provides a backdrop of how Berkshire’s boss has been able to deliver outsized returns spanning six decades.

Fundamentally, Warren Buffett is well aware that the U.S. economy and stock market have both expanded over the long run. Even though recessions and stock market corrections are normal and inevitable aspects of respective economic and stock market cycles, optimism prevails over long periods. This means being patient and waiting for price dislocations to become apparent is a winning and time-tested strategy — in case the nearly 6,140,000% aggregate return for Berkshire’s Class A shares didn’t give it away.

In August 2011, shortly after the worst of the financial crisis, the Oracle of Omaha engineered a $5 billion stake in Bank of America (BAC -1.29%) preferred stock. While Bank of America wasn’t desperate for cash, it wasn’t going to turn down the opportunity to shore up its balance sheet amid ongoing litigation and a still-uncertain loan portfolio.

When Buffett initially made this investment, Bank of America’s common stock was trading at a 62% discount to its book value. But in the summer of 2017, Berkshire exercised its warrants to purchase 700 million shares of BofA stock at $7.14 per share. This August 2011 price dislocation instantly netted Berkshire a $12 billion (unrealized) profit, which has since grown even larger.

Berkshire’s billionaire CEO recognized a price dislocation with Apple (AAPL -0.16%), as well, in early 2016. The maker of the beloved iPhone was trading at just 10 to 15 times forward-year earnings nine years ago, which is an inexpensive valuation for a company that had been consistently growing by high single digits to low double digits annually. Apple stock has jumped approximately tenfold since Buffett first entered the position, with artificial intelligence euphoria and the company’s rapidly growing services segment doing a lot of the heavy lifting.

Although it can be frustrating waiting for Warren Buffett and his top advisors to deploy Berkshire Hathaway’s treasure chest, being patient has paid off handsomely for decades. When price dislocations do become apparent in the future, Buffett or his successor Greg Abel will be ready to pounce.
