Regal Rexnord, ESAB, Standex, Sanmina, Curtiss-Wright Surge as AI-Driven Tech and Bitcoin Recovery Lift Mid-Cap Gains

On February 06, 2026, mid-cap stocks including Regal Rexnord, ESAB, Standex, Sanmina, and Curtiss-Wright surged as broader markets rebounded from a tech-driven sell-off. The rally was bolstered by a stabilization in Bitcoin after a sharp decline from its October peak, improved U.S. consumer sentiment, and the realization that major AI CAPE spending benefits chipmakers like Nvidia and Broadcom. The S&P 500 edged into positive territory for 2026, and the Dow crossed 50,000 for the first time. Regal Rexnord posted an adjusted EPS of $2.51 vs. $2.48 expected in Q4 2025, with revenue of $1.52B below the $1.54B estimate. The company guided full-year adjusted EPS at $10.60, slightly below forecasts, but its operating margin expanded YoY from 8.8% to 10.8%. The stock rose 6.7% on January 24, 2026, on mixed results, and is up 45.1% YTD at $211.93/share, reaching a 52-week high. A $1,000 investment would be worth $1,620 as of February 06, 2026.
