[BRIEFING.COM] The S&P 500 (+1.10%) is in second place on Friday afternoon, just off highs of the session.
Elsewhere, S&P 500 constituents Enphase Energy (ENPH 118.77, +7.09, +6.35%), Builders FirstSource (BLDR 154.92, +8.03, +5.47%), and ON Semiconductor (ON 77.66, +3.42, +4.61%) pepper the top of the standings. Solar stocks, including ENPH, display general strength today, while BLDR is benefiting from gains in rate-sensitive stocks, with ON and peers recovering nicely after the PHLX Semiconductor Index (SOX 5851.33, +151.67, +2.66%) lost -3.47% yesterday.
Meanwhile, Align Tech (ALGN 244.76, -11.54, -4.50%) is one of today's top laggards despite a dearth of corporate news; peer Envista (NVST 15.92, -0.82, -4.90%) also displays weakness.
