Xueqiu

Xueqiu is a Chinese investor community centred on discussion of listed companies, with portfolios, posts and data on both A-shares and overseas-listed Chinese stocks.

Its value is the analysis written by individual investors, some of whom publish detailed company research that is not available elsewhere in Chinese.

As with any investor forum, positions influence what people write: a poster holding a stock has an interest in others buying it, so read the reasoning rather than the conclusion.
