US stock market volatility and rising Treasury yields
Overview
By late October 2026, the S&P 500 has navigated significant volatility driven by high valuations and concerns over market concentration. While the index maintained a year-to-date increase of approximately 12% to 13.8%, analysts have warned of underlying weaknesses, noting that approximately 44% of stocks had recently entered bear-market territory. Valuation concerns remained acute as the Shiller CAPE ratio crossed the 40 threshold, reaching levels near 42.2.
Market volatility was exacerbated by massive artificial intelligence spending. Meta Platforms reported record quarterly revenue of $64 billion, yet its stock faced pressure following reports that it raised AI-related capital expenditure estimates to a range of $135 billion to $145 billion. This spending contributed to a negative free cash flow of $2.12 billion in the third quarter of 2026, Meta’s first deficit since 2012. Internal tensions also emerged at Meta, with reports of a conflict between CEO Mark Zuckerberg and the board of directors regarding AI spending and executive compensation.
By October 29, a significant divergence emerged between headline index highs and broader market breadth. While mega-cap technology leaders like Nvidia, Microsoft, and Meta have driven the cap-weighted index to record levels, approximately 60% of S&P 500 stocks are trading below their 200-day moving averages. The median stock sits nearly 20 percent below its record high, creating a gap between the cap-weighted and equal-weighted versions of the index not seen since the dot-com era. Morningstar analysts identified the “Undervalued Seven” (Nvidia, Alphabet, Broadcom, Microsoft, Meta Platforms, Amazon, and Tesla) as the sole drivers of market undervaluation.
Capital Economics warned of the sustainability of the AI-driven rally, forecasting the S&P 500 could fall to 6,500 by the end of 2027 if the momentum trade fades. Despite these risks, third-quarter earnings growth remained strong, with blended growth rates estimated at 29.5 percent.
