Current overview (not historical)

- DecryptRelated fact: single sourceSource report revisedChina's stock market loses $2.4 trillion as AI boom doubts weigh on valuations
Report first recorded Oct 28, 05:18
Chinese mainland stocks have lost about $2.4 trillion in market value since May, with the STAR 50 index of tech and chip companies down 40% in under four months. AI companies account for 42% of the market value and 57% of trading volume on Chinese shares, and their declines are dragging down the broader CSI 300 index, which entered a bear market in late October. The sell-off is attributed to weak consumer spending and doubts about whether AI firms can earn back their investments, while U.S. export controls on chips and robot parts add further pressure.

- BeInCryptoRelated fact: single sourceChina's CSI 300 Index Enters Bear Market Amid Fading Stimulus Hopes and AI Trade Worries
Report first recorded Oct 22, 15:08
China's benchmark CSI 300 index entered a bear market on Thursday after 10 straight weeks of decline, standing at 4,060.19, which is about 20% below its June peak and 13.94% down from its January 1 level. This decline was linked to fading stimulus hopes, weak earnings, and concerns over the global artificial intelligence (AI) trade. The pressure spread across Asia, with South Korea's KOSPI, Japan's Nikkei 225, and Taiwan's TAIEX also falling. Despite state-backed buying efforts by Central Huijin, which has reinvested only about $43 billion since July, analysts warn that state buying alone may not ensure a lasting recovery. In contrast, sovereign wealth funds invested $14.2 billion into mainland China and Hong Kong through September.
