Warren Buffett is one of the most successful investors of all time. And over the past six decades, his Berkshire Hathaway portfolio has trounced the market, returning an average compound annual return of 19.7% compared to the S&P 500 index’s average of 10.5%.
With such an amazing track record, people tend to listen to what he has to say. High-quality advice is more valuable than ever as the stock market grapples with challenges ranging from high corporate valuations, rising inflation, and political uncertainty.
Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »
Let’s discuss several recent warnings Buffett has given and decide what it could mean for your portfolio.
Buffett decries a “gambling mood” in the market
Warren Buffett is famous for focusing on value stocks, which are generally shares in companies that trade for affordable prices compared to their earnings and growth. However, these diamonds in the rough are getting harder to find. In a May interview with CNBC, Buffett criticized a “gambling mood” in the stock market and raised concerns about equity prices.
It isn’t hard to see why he is getting worried. The cyclically adjusted price-to-earnings (CAPE) ratio is a valuation tool designed to help investors analyze the S&P 500’s valuation from a long-term perspective. Right now, it stands at 40.7. That’s well above its average of 17.4 and a level that has only been exceeded during the dot-com bubble when it hit an all-time high of 44 in late 1999 before a big crash.

Buffett’s also has concerns about America’s fiscal situation
Unlike more outspoken business leaders like Elon Musk, Warren Buffett has typically avoided inserting himself directly into politics — and wisely so. That said, the situation may be becoming too alarming to ignore. And in his final meeting as Berkshire Hathaway CEO in May 2025, Buffett had some very blunt words to say about the US fiscal situation.
“We wouldn’t want to be owning anything that we thought was in a currency that was really going to hell, and that’s the big thing we worry about with the United States currency. We’re operating at a fiscal deficit now that is unsustainable over a very long period of time.”
A little over a year and a half later, and the situation he was warning about has become significantly worse. The Trump administration maintained its aggressive tariff policy, and the war in Iran has caused Brent Crude prices to spike 80% since the start of the year. September inflation has jumped to 3.7%, well above the Federal Reserve’s long-running target of 2%.
