SHANGHAI/NEW YORK : Billionaire hedge fund manager Ray Dalio's huge popularity in China has not only drawn local investors flocking to his funds but also spawned home-grown challengers using his "All Weather" strategy and brand to try to beat him at his own game. In recent months, Bridgewater registered in China several "All Weather" trademarks in English and Chinese, an effort to tackle the "confusion" created by local copycats, said Joanna Alpert, Bridgewater China's portfolio manager. "We'll continue to enforce our rights and protect our IP," Alpert, also a partner at Bridgewater, told Reuters.
