Buffett's "favorite indicator" has risen to a record high. Is this a sell signal?

Billionaire Warren Buffett's preferred indicator, which reflects the ratio of U.S. stock market capitalization to U.S. annual GDP, has risen to a record high. The indicator now stands at about 232.5%, up 13% from its March low. It is also the maximum in the history of GuruFocus observations since 1970, writes Yahoo Finance. The indicator appeared to be in the "significantly overvalued" zone of the market: this could mean that stocks are at risk of showing moderately negative returns over the next year, Yahoo Finance explains.

It is becoming increasingly difficult to argue that the valuations of U.S. stocks have reached alarming levels, Yahoo Finance writes. The volume of trading in shares of American companies with a high EV/Sales multiple, which reflects the ratio of the company's value including debt to its annual revenues, has approached the highest levels in decades, the publication notes. This indicator was higher only during the dot-com bubble in 2000, according to a study by Goldman Sachs strategist Ben Snyder.

"The swiftness of the recent stock market rally has investors worried about the sustainability of the bull market and is prompting them to look for signals that a top is near," Snyder noted.

The Buffett indicator is calculated as the ratio of the Wilshire 5000 Index, which is considered a reflection of the entire U.S. stock market, to annual U.S. GDP. The indicator became widely known after an article in Fortune magazine, published in 2001, recalls Yahoo Finance. Its authors were Buffett and Fortune columnist Carol Loomis.

"The ratio has certain limitations in terms of assessing what investors really need to know," Buffett explained in that article. - Nevertheless, it is probably the best single indicator of where market valuations are at any given time."
