Macau casino stocks’ high-rolling days are over Jacky Wong, Wall Street Journal · November 29, 2021 at 6:19 am Macau’s losing streak isn’t over yet. High-rollers from China and their financiers—previously a big revenue source for casinos—seem likely to focus on keeping their own heads from rolling rather than resuming their profligate ways next year. Shares of casino operators in the semiautonomous Chinese city plunged Monday after the government said that the chairman of the city’s biggest junket operator was being held for questioning. Wynn Macau fell 8% while MGM China dropped 10%. Trouble is brewing up north: The Chinese city of Wenzhou has issued an arrest warrant for Alvin Chau, chairman of junket operator Suncity, accusing him of running a cross-boundary gambling syndicate to illegally recruit Chinese residents to gamble outside of mainland China. Chinese state media previously condemned Suncity two years ago for facilitating capital outflows with an online gambling platform.
