[BRIEFING.COM] The S&P 500 (+0.42%) is in last place on Tuesday afternoon, up about 29 points.
Briefly, S&P 500 constituents Regeneron Pharma (REGN 638.00, +52.69, +9.00%), MSCI (MSCI 587.98, +41.12, +7.52%), and Intel (INTC 41.47, +1.93, +4.88%) pepper the top of the standings. REGN and MSCI rise amid strong earnings, while INTC bubbles higher amid strength in mega-cap tech and chipmakers with NVIDIA's (NVDA 199.38, +7.89, +4.12%) GTC from Washington, D.C. ongoing.
Meanwhile, F5 Networks (FFIV 268.26, -22.15, -7.63%) is one of today's worst laggards, after the company's strong Q4 results were overshadowed by weak FY26 guidance, with EPS and revenue expected below consensus due to near-term sales disruptions from a recent security incident.
