Midday Report: Shake Shack Swings to Profit; U.S. Stocks Fluctuate

U.S. stocks fluctuated as an impressive read on April retail sales countered a recent run of disappointing earnings from retailers. Macy's (M) - Get Report , Kohl's (KSS) - Get Report and Nordstrom (JWN) - Get Report have each reported a challenging start to 2016. Consumer sentiment backed up the upward trend in retail sales. Sentiment in early May climbed to its highest in nearly a year, according to the University of Michigan index. Symantec (SYMC) - Get Report fell short of analysts' expectations in its fourth quarter. Symantec also announced plans to cut roughly 10 percent of its workforce as part of a reorganization. Shake Shack (SHAK) - Get Report jumped after swinging to a first-quarter profit and hiking its full-year sales outlook. The burger chain said the launch of its chicken sandwich had driven store traffic in the start to the year. TheStreet's Keris Lahiff reports from Wall Street.
