Asset Allocation Blogger James Picerno: Why Rising Treasury Yields Haven't Broken the Equity Bull Market Yet
James Picerno argues that despite surging Treasury yields, high-beta and momentum factors remain in leadership, the SPY-to-USMV ratio continues trending higher, and S&P 500 Q3 earnings estimates are above their start-of-quarter levels. He explains how these internal signals form a diagnostic framework for distinguishing a temporary pause from a genuine correction, and what conditions would invalidate that reading.

In an article dated October 5, 2026, asset allocation blogger James Picerno addresses a central contradiction: while bond yields have risen sharply over the past month—typically a headwind for stocks—the S&P 500 is trading near record highs with volatility at historically normal levels. Picerno argues this resilience is supported by internal market structure, and that unless specific conditions change, current weakness represents a pause in the uptrend rather than the start of a prolonged correction.
Picerno's analytical framework focuses on a factor lens. He notes that the key drivers of this year's rally, particularly High Beta (SPHB) and Momentum factors, continue to lead by a wide margin year-to-date. Large-cap growth funds like IVW rallied to new highs last week. These signs indicate that investors have not fled risky assets due to higher rates but are instead continuing to seek opportunities in stocks sensitive to economic expansion.
To quantify this risk appetite, Picerno cites the ratio of the broad market ETF (SPY) to the low-volatility ETF (USMV). Typically, when uncertainty rises, investors rotate into low-volatility stocks as safe havens, causing this ratio to fall. However, current charts show the SPY:USMV ratio trending higher, suggesting investors are inclined toward risk-taking and downplaying concerns about further increases in interest rates and inflation. Meanwhile, defensive characteristics such as high-dividend stocks (VYM) and small-caps (IJR) have shown relative weakness, reinforcing the flow of capital into offensive assets.
