The U.S. stock market is printing fresh highs again, but one of Wall Street’s best-known valuation gauges is flashing a far less comfortable message. This time, the warning is coming from the so-called “Warren Buffett Indicator,” which has climbed to its highest level on record as major indices keep pushing upward.

A market trading at record highs while its broadest valuation gauge also sits in uncharted territory is likely to invite fresh debate over whether the rally reflects durable earnings strength—or just a growing willingness to pay almost any price for AI-led growth.
