梁文锋基金也在亏损？幻方量化多只产品年内收益转负，单月跌幅超20%

Odaily News: According to statistics from the private fund ranking platform (私募排排网), as of July 31, 2026, among the 9 mainstream quantitative products publicly displayed by Liang Wenfeng's High-Flyer Quant, 8 have turned from positive to negative returns this year. Only the Jiuzhang High-Flyer CSI 500 Quantitative Multi-Strategy No. 2 managed to maintain a marginal positive return of 0.04%. Notably, several products saw their net value plunge by more than 20% in a single month.

As a benchmark institution in China's private quantitative fund sector, Ningbo High-Flyer Quant was founded by Liang Wenfeng and has long been a mainstay in the 10-billion-yuan quantitative tier. Unlike other quantitative firms, High-Flyer is one of the few private fund managers in China to truly achieve "AI end-to-end empowered investing." Liang Wenfeng is also the founder of DeepSeek, a leading domestic large language model. High-Flyer has long built its own computing clusters, relying on machine learning and deep learning models to construct stock selection and trading systems, and was once viewed by the market as an industry model for AI-driven quantitative investing. Over the past few years, High-Flyer's CSI 500 and CSI 1000 index-enhanced products consistently delivered impressive excess returns, attracting significant high-net-worth capital through stable performance, with assets under management at their peak surpassing 100 billion yuan. However, this collective pullback in net value has shattered investors' prior expectations that AI-powered quant strategies could "navigate volatility with ease." (Interface News)
