Goldman Sachs analysts, led by Ben Snider, report that S&P 500 market breadth has narrowed to levels last seen during the dot-com bubble. Despite the index rising 14% in 2026 and remaining near its August peak, the median stock is trading 16% below its 52-week high.
The firm's U.S. Equity Sentiment Indicator dropped to -0.9, matching the low recorded in March 2026. Additionally, the forward price-to-earnings ratio for the index has decreased from 22x to 19x, aligning with the ten-year average.
Currently, fewer than 50% of S&P 500 companies trade above their 200-day moving averages. Historical data indicates that such a divergence between index performance and individual stock breadth has been rare since 1990, with similar patterns occurring between 1998 and 2000.
Earlier in 2026, Goldman Sachs noted a 13% median shortfall for stocks in May and observed breadth in the 94th percentile in June. Analysts attribute current market pressure to rising interest rates and skepticism regarding the sustainability of AI-driven profits.
The report suggests that a decrease in macroeconomic uncertainty could facilitate broader market recovery. The current compression of the forward P/E ratio and the sentiment indicator reading indicate that institutional investors are already accounting for these risks.
