Stock Market Update

[BRIEFING.COM] The S&P 500 (+1.3%), Nasdaq Composite (+1.9%), and DJIA (+0.9%) steadily add to their impressive opening gains. 

While much of today's coverage centers around tech names following Micron's (MU 251.68, +26.16, +11.60%) blowout earnings report, the consumer discretionary sector (+2.5%) is actually the top gainer this morning, with several notable storylines of its own. 

Amazon (AMZN 227.99, +6.72, +3.04%) and Tesla (TSLA 483.79, +16.53, +3.54%) provide solid mega-cap leadership after retreating yesterday.

Meanwhile, lululemon athletica (LULU 219.36, +11.49, +5.53%) holds one of the widest gains in the sector after The Wall Street Journal reported that Elliot Investment Management has built a position exceeding $1 billion. 

Darden Restaurants (DRI 196.48, +6.94, +3.66%) is another top mover despite missing on EPS for the second consecutive quarter, as investors have focused on solid top-line performance and a meaningfully improved outlook.

Lennar (LEN 110.64, -1.59, -1.42%), however, extends yesterday's losses after an EPS miss of its own.
