Value's 800bp Weekly Rout: Yield Curve Repricing Triggers Record Factor Rotation

2026-10-30, FP360 — The Russell 1000 Value index sank 2.8% this week while Momentum surged 3.1%, an 800bp spread that marks the sharpest factor rotation since March 2020. The trigger: 10-year Treasury yields jumped 18bp to 4.68% and 2s10s steepened to 58bp as term premium repriced on fiscal concerns and sticky inflation, pummeling long-duration value sectors like banks and energy while momentum's tech and growth winners rallied on AI capex optimism. The rotation threatens $1.2 trillion in value-tilted ETF assets, forcing quant funds to unwind crowded positions as factor volatility spikes.

The Signal: Momentum's relative strength will persist until 10-year yields stabilize below 4.50%, but stretched positioning risks a violent reversal if inflation surprises to the downside.
