Warren Buffett's favorite stock-market indicator has climbed to a record high, signaling stocks are overvalued and another crash could be coming.

The so-called "Buffett Indicator" takes the combined market capitalizations of a country's publicly traded stocks and divides it by quarterly gross domestic product. Investors use it to gauge whether the stock market is overvalued or undervalued relative to the size of the economy.

Buffett, a billionaire investor and the boss of Berkshire Hathaway, described it as "probably the best single measure of where valuations stand at any given moment" in a Fortune magazine article in December 2001.

The indicator has its flaws, including GDP not counting income earned overseas, and US-listed companies not necessarily contributing to the US economy.

Yet it has a strong track record of predicting future downturns. For example, it surged to 118% just before the dot-com bubble burst in 2000, and topped 100% before the 2008 financial crisis.

"Nearly two years ago the ratio rose to an unprecedented level,"Buffett said in the 2001 Fortune article. "That should have been a very strong warning signal."

The Buffett indicator now sits at a historic high of 179%, reflecting the US stock market's rapid rebound since the coronavirus sell-off, and the 4.8% slump in annualized GDP last quarter. Its current level is well above the average reading of 107% over the past 20 years.

Several market commentators have questioned whether US stocks are overvalued in light of slowing economic growth, surging unemployment, and other alarming data in recent weeks.

The latest Buffett indicator reading will likely add more weight to their worries.
