Stock Market Update

[BRIEFING.COM] As the market nears midday, the major averages sit with healthy gains, trading in a relatively tight range near session highs. 

The S&P 500 has advanced 0.7%, leaving it just 1.3% beneath last week's record intraday high.

Though the advance is largely buoyed by mega-cap outperformance today, there are still some noteworthy individual gainers in respect to this morning's earnings reports.

Arista Networks (ANET 138.73, +20.61, +17.5%) is the top performer in the S&P 500 after beating expectations and raising guidance, with Shopify (SHOP 151.78, +24.78, +19.5%) and Match Group (MTCH 36.91, +3.18, +9.4%) also posting substantial gains.
