[BRIEFING.COM] The S&P 500 (+1.31%) is in second place on Monday afternoon, up more than 80 points.
Briefly, S&P 500 constituents IDEXX Labs (IDXX 676.01, +140.47, +26.23%), Williams-Sonoma (WSM 198.58, +10.91, +5.81%), and Monolithic Power (MPWR 830.64, +45.02, +5.73%) pepper the top of the standings. IDXX is far and away the best performer in the average today, after delivering a strong Q2 earnings beat and raising full-year guidance well above consensus, driven by accelerating demand for its new veterinary diagnostics technologies.
Meanwhile, onsemi (ON 49.28, -7.54, -13.27%) slides to the bottom of the average after issuing a tepid Q3 outlook that suggests only modest sequential growth, disappointing investors hoping for a stronger recovery in its core automotive and industrial markets.
