Desk brief
China’s quantitative investment sector suffered a sharp setback in July as an unwind in artificial-intelligence-linked shares reversed crowded positions. A fund tracking the CSI 1000 Index at Zhejiang High-Flyer Asset Management, the firm associated with DeepSeek founder Liang Wenfeng, fell 15.7% in the week ended July 17.

The losses underscore the concentration risk that built up around China’s AI supply chain after a strong first half of 2026.
