Why shares of Marriott , MGM Resorts, and Eldorado rose today Rich Duprey, The Motley Fool · June 29, 2020 at 10:38 pm Travel and tourism stocks rose on Monday even though the number of COVID-19 cases over the weekend rose, as investors bet on states continuing to reopen their economies despite the spike. Shares of Marriott International (NASDAQ:MAR) and MGM Resorts International (NYSE:MGM) were up 6%, while Eldorado Resorts (NASDAQ:ERI) rose over 9%. There was no company-specific news on any of these stocks today, although Eldorado did receive Federal Trade Commission clearance on Friday for its merger with Caesars Entertainment (NASDAQ:CZR). Instead, the stocks rose on hopes for the broader macroeconomic climate. Las Vegas casinos reopened their doors earlier this month, and they will require patrons to wear masks while on premises. MGM Resorts reportedly received guidance from Nevada that performers must wear masks, too, even while performing, though they may be briefly pulled down to sing.
