U.S. cash markets closed Thursday with the S&P 500 just shy of its all-time high, capping a week that saw the index gain 1.0% and then add another 3.0% through Thursday's session. The subdued pullback in Thursday's trading belies underlying momentum, but valuation gauges are signaling that investors may be paying top dollar for future returns.
The so-called Buffett Indicator, which compares the total market capitalization of U.S. equities to gross domestic product, stands at a preliminary 232%. A similar metric calculated by the Federal Reserve using first-quarter data puts the ratio at 250%. The 18-point spread between these two readings underscores how sensitive the indicator is to methodology, making it a poor tool for precise market timing but a useful barometer of stretched valuations.
Warren Buffett himself has voiced caution. In May, he remarked, "We've never had more people in a gambling mood than now," adding that some prices might later look "awfully silly." While the Oracle of Omaha's comments have not triggered a selloff, they serve as a reminder that elevated valuations can compress future returns.
Part of the market's resilience is underpinned by robust earnings. S&P 500 companies are on track to post a 31.1% year-over-year increase in second-quarter profits, with growth expected in ten of the index's eleven sectors. The forward price-to-earnings ratio has eased to 20.4 from 22.2 at the end of 2025, but it remains well above historical norms.
Other valuation measures paint a similar picture. The Shiller CAPE ratio, a cyclically adjusted price-to-earnings metric, stands at 42.19 versus a long-run average of 17.40 and a record high of 44.19. These gauges do not predict short-term market direction, but they do suggest that long-term return expectations should be tempered. Spencer Jakab of The Wall Street Journal recently noted that the indicator implies investors should anticipate reduced long-term returns rather than an imminent crash.
Berkshire Hathaway (NYSE:BRK.B) will provide a clearer signal on Saturday when it releases second-quarter results. The company's first-quarter operating earnings rose 17.7% to $11.35 billion, but share buybacks totaled just $234 million—a mere 0.06% of its $380.2 billion cash pile. That limited repurchase activity hinted at management's reluctance to deploy capital at prevailing prices. The upcoming 10-Q filing will reveal whether that stance has shifted.
CEO Greg Abel affirmed in May that the company can "create long-term value for shareholders." The buyback data will serve as an early test of that commitment. Analysts remain cautiously optimistic, with a consensus Buy rating and an average price target of $525.33—just 36 cents above Thursday's closing price of $524.97. The small sample of four analysts includes UBS's Brian Meredith (Buy, target $585) and Argus Research's Kevin Heal (Buy, no target), while Edmond Fok of DBS Group holds at $500.
Looking ahead, a series of economic releases will test whether high valuations can be sustained. Friday brings the July employment report, which could influence interest rate expectations and bond yields. Wednesday's consumer price index and Thursday's producer price index will shed light on inflation trends, while Friday's retail sales data will gauge consumer spending resilience. Strong payroll numbers could push yields higher and pressure richly valued stocks, while weak data might have the opposite effect.
These valuation metrics do not indicate when a correction might occur. Stronger earnings growth or declining yields could keep prices elevated, and geopolitical disruptions could overshadow fundamental signals. Buffett's caution underscores the importance of price discipline rather than a wholesale exit. Berkshire's buyback decision will offer a tangible clue as to where opportunities—if any—remain in this market.
