The consumer-discretionary sector rose on Tuesday, recovering from a steep decline in the previous session as two of its largest components gained on the day. The sector XLY, +0.49% rose 1%, the biggest percentage gainer among the 11 primary S&P 500 industry groups. The sector was supported by Amazon.com Inc. AMZN, +0.40% which rose 2.1% in a rebound from the previous session's sharp drop, which was spurred by President Donald Trump repeatedly tweeting against the company. The online retail giant is by far the largest component of the discretionary sector, accounting for about 20% of its market capitalization. Netflix Inc. NFLX, +1.01% another highly influential stock in the sector, climbed 3.8%.
