China's Young Fund Managers Face Billion-Yuan Mandates Amid AI Market Turmoil

economy-finance · 2026-08-15

Amid a 50-day period of market upheaval, emerging portfolio managers in China faced increased scrutiny as their technology investments faltered. Yuan Zeqiang, who has three and a half years of experience in sell-side research, witnessed his two inaugural portfolios at Caitong Fund Management decline by 36% and 33%, respectively, from his appointment on June 11 to July 30. He took over assets totaling 7.28 billion yuan (US$1.08 billion) at the close of Q2, a notably substantial responsibility for a novice manager. The swift downturn was primarily due to significant investments in tech stocks, which fell after earlier substantial increases. Similarly, across the Pacific, Leopold Aschenbrenner's US hedge fund experienced a loss of over two-thirds of its assets in just one month. Yuan is not isolated in this fiercely competitive landscape, as other novice managers faced comparable difficulties.
