[BRIEFING.COM] The S&P 500 (+1.52%) is in second place on Thursday afternoon, up about 110 points.
Briefly, S&P 500 constituents Sandisk (SNDK 1255.29, +239.40, +23.57%), EMCOR Group (EME 797.13, +124.65, +18.54%), and Quanta Services (PWR 646.88, +85.74, +15.28%) dot the top of the standings. Both EME and PWR rise following earnings.
Meanwhile, C.H. Robinson (CHRW 146.10, -27.65, -15.91%) falls hard owing in part to profit taking after a strong run-up into earnings and focusing on management's comments that the freight market remains in a prolonged downturn, with limited signs of a near-term demand recovery despite the company's operational improvements.
