(Bloomberg) On any given evening, after Mark Hart and his wife have put their kids to bed, he’ll duck into his bedroom closet and close the door behind him. Then, by pixel-light, he goes to work. Hart, a hedge fund manager in Fort Worth, has a single fixation: the Chinese yuan. And at 9 p.m. Texas time, China’s financial markets are in full-throated roar 13 time zones away.
Surrounded by shirts and pants—the closet is more convenient than his basement office—Hart, 44, talks to Hong Kong, parsing the latest numbers and the scuttlebutt from Beijing and Shanghai. In the seven years since this all started, he might as well have learned Mandarin. (All three of his children speak the language now, unlike their old man.) Doggedness has cost him millions—not to mention investors, employees, and, at times, damn near his sanity. But he won’t, or maybe can’t, let go now.
