The S&P 500 (SNPINDEX: ^GSPC), Nasdaq Composite (NASDAQINDEX: ^IXIC), and Dow Jones Industrial Average (DJINDICES: ^DJI) have all been reaching new heights over the past few years, as investor optimism fueled lucrative growth
However, it’s possible to have too much of a good thing, and what goes up must eventually come back down. Warren Buffett is no stranger to market downturns, and he recently issued a warning about investing in today’s market. Here’s what history says investors can expect
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 »
Investors could be “gambling” right now
In an interview with CNBC during Berkshire Hathaway’s 2026 annual meeting, Buffett bemoaned the risk-taking culture that has become common in today’s financial markets
He noted that he often compares the market to a church with a casino attached, with the former representing long-term value investing and the latter, short-term betting
“The casino has gotten very attractive to people,” he said, emphasizing that “that’s not investing, it’s not speculating, it’s gambling.” He added, however, that “that doesn’t mean that investing is terrible. It does mean that prices for an awful lot of things will look very silly.”
What history says is coming next
History suggests that Buffett’s not wrong in this assertion. Valuations have been soaring over the last few years, and multiple stock market metrics suggest many stocks may be overvalued right now
Warren Buffett’s own preferred metric — the Buffett indicator — recently reached its highest point in history. This figure measures the relationship between the total value of U.S. stocks and GDP, and Buffett himself noted that when it nears 200%, investors are “playing with fire.” As of this writing, it sits at 232%
The S&P 500 Shiller CAPE Ratio is another metric nearing risky territory. It measures broad market valuations by tracking the S&P 500’s 10-year inflation-adjusted earnings, and it’s also nearing a record high
This ratio has consistently hovered above 40 since May, and the only other time in history it’s stayed above this level was leading up to the dot-com bubble burst — when it peaked at just over 44
There’s still good news for investors
It’s impossible to say whether we’re headed toward a dot-com-like bear market in the coming months or years, as even Warren Buffett can’t predict the market’s future. However, if history proves just one thing, it’s that the right investments will pull through volatility
