Among other stocks, Facebook Inc. rose 3.6% on Monday, Amazon.com Inc. added 3.5%, and Google-parent Alphabet Inc. climbed 2.3%. Microsoft Corp. closed up 1%, as did Netflix Inc. All have outperformed the broader market this year; Alphabet is the weakest performer of the bunch, up 32%, but that move is still roughly double the 15.6% rise of the S&P 500.
