HONG KONG : A leading Chinese hedge fund, High-Flyer Quant, said it has suspended its co-founder and senior executive Xu Jin from work due to his "improper handling of a family matter". The Hangzhou-based quantitative fund did not specify what Xu had done or what role of his has been suspended but said in a statement published on its official WeChat account late on Thursday it "caused negative public opinion and had a negative impact on company reputation". High-Flyer Quant did not immediately respond to an emailed request for comment.
