According to CoinMeta, investors supported by the Chinese state may have injected approximately $25.5 billion into the domestic stock market this month in an attempt to stabilize a market that has lost around $3.5 trillion since May. According to the South China Morning Post, this buying activity helped the CSI 300 index rise by 0.9% on October 28. However, investment banks warn that even with significant government intervention, it may only slow down the selling pressure unless China's economy and corporate profits begin to improve. Analysts estimate that these institutions made purchases totaling 170 billion yuan (about $25.5 billion) in October. These purchases represent a form of intervention, rather than a newly announced government stimulus plan.
