S&P 500 Index: Why Vanguard Is Bearish on the Index

Analysts at Vanguard have predicted that the performance of the S&P 500 Index and its major components will fall short of expectations. The ETF and mutual fund company forecasts that the average annual growth of the U.S. stock market over the next 10 years will be only 3.5% to 5.5%, far below the S&P 500's long-term average annual return of about 10%. This stands in stark contrast to recent forecasts for the index by Wall Street experts. So why is Vanguard so pessimistic?

In its latest investor report, Vanguard predicts that the average annual return for U.S. growth stocks over the next decade will be only 2.3% to 4.3%. This is a sharp contrast to the recent market environment, where growth stocks have led the way. This year, the S&P 500's roughly 17% gain is largely due to large-cap growth stocks. Therefore, Vanguard's sudden shift is concerning and signals a less optimistic outlook for the future.

"Even with current elevated valuations, earnings growth may still provide short-term momentum for the stock market," Vanguard stated. "However, we are increasingly convinced that the long-term outlook for the U.S. stock market is bleak."

Other Wall Street Players Remain Bullish on the S&P 500

On the other hand, JPMorgan's top equity market strategists have issued a bullish price forecast for the S&P 500 Index (^GSPC), indicating their confidence in the stock market through 2026. In fact, the JPMorgan equity strategy team led by Dubravko Lakos-Bujas has set a target of 7,500 points for the index by the end of 2026. "Despite concerns about an artificial intelligence bubble and overvaluation, we believe that the current higher price-to-earnings ratios correctly signal above-trend earnings growth, a surge in AI capital expenditures, increased shareholder payouts, and accommodative fiscal policy (such as [a comprehensive bill])," the institution wrote in a client report at the end of November.

In addition, Deutsche Bank has also issued an optimistic forecast for the S&P 500. The bank predicts that the S&P 500 will also break through the 8,000-point mark. Deutsche Bank points out that AI-driven gains will boost corporate earnings, potentially ushering in a golden era for the S&P 500. The bank also quickly predicted that S&P 500 earnings per share could eventually reach $320.
