Wall Street bulls flag pullback risk as S&P 500 trades at 21x earnings

The S&P 500 enters the second half at 21.4 times estimated 2026 earnings, prompting even typically bullish strategists to warn of a pullback.

"At 21.4 times estimated 2026 earnings and 18.5 times 2027 estimates, stocks are not cheap," said Bill Stone, a senior investment strategist and Forbes contributor. "Higher valuations are a headwind for further stock gains."

Last week's selloff was concentrated in AI and technology names, with the Magnificent 7 underperforming while the average stock gained 1.6%, according to Forbes. The iShares Future AI and Tech ETF remains up more than 50% year to date despite falling 10.4% from its peak. The semiconductor sector is still up 37.8% year to date.

The risk is that elevated inflation — running near 4% according to the Cleveland Fed — keeps the Federal Reserve on hold or even hiking through 2026, a scenario that would pressure equity multiples further. The next test comes this week with June payrolls data, where economists expect 118,000 new jobs and the unemployment rate at 4.3%.

The pullback warnings come after a first half that saw the S&P 500 deliver strong returns despite the Iran conflict and oil price spike. Second-quarter GDP growth is expected around 2.5%, and recession odds have fallen to 1-in-10, according to Kalshi betting data cited by Forbes.

But the macro picture carries competing signals. The Cleveland Fed's inflation nowcast shows consumer prices rising at close to 4% year over year, well above the central bank's 2% target. That has shifted rate expectations: a Reuters poll published June 26 showed more than three-quarters of economists expect the Fed to hold rates through 2026, defying earlier market bets on cuts.

Tech-led selloff exposes concentration risk

The rotation away from AI leaders into the broader market was visible in the advance-decline data. The average stock gained 1.6% even as the Magnificent 7 lagged, a pattern that suggests investors are repositioning rather than exiting equities entirely. Micron Technology, which raised its earnings guidance, declined only fractionally last week, while the software sector — down more than 21% year to date — held up well during the tech rout.

Cross-asset pressure builds

The equity market faces headwinds from multiple directions. The U.S. 10-year Treasury yield has remained elevated as inflation expectations stay sticky. Gold fell 3.4% last week and silver dropped 10.5%, while Bitcoin declined 5%, showing that the selloff extended beyond equities. Oil prices have provided some relief, with Brent crude falling to $71.99 a barrel on June 26 from war-driven highs above $110, though fresh U.S.-Iran strikes on June 27 tested the fragile ceasefire.
