Chinese stocks entered bear-market territory, with mainland shares losing $2.4 trillion in market value since their May peak, according to a Bloomberg estimate. The CSI 300 Index closed down 1.8% on Thursday, October 22, bringing its total decline from its June peak to 20%. The drop underscores mounting pressure on the market, as shares fell alongside concerns about the sustainability of their gains and the profitability of artificial intelligence companies. Bloomberg's report also linked the losses to continued weakness in consumption, as indicators of domestic demand remained a concern for Chinese authorities. These factors place the index's decline in a broader economic context than the moves of a single session.

Bloomberg's report said growing doubts about the profitability of artificial intelligence companies added to pressure on shares, alongside fading expectations for stimulus and a lack of new catalysts. The report said Chinese stocks had become among the world's worst performers as the consumption slump persisted. Data from the National Bureau of Statistics show that retail sales of consumer goods rose 1.1% year on year in September. Sales growth was the same rate over the first nine months of 2026, according to official data. The reading provides an indication of consumer spending during the downturn cited in the market report.

By contrast, investment in real estate development fell 20.6% year on year from January to September 2026, according to National Bureau of Statistics data. The decline in the property sector forms part of an economic picture accompanied by weak domestic demand, the bureau said. The bureau also said, "The problem of insufficient domestic demand remains prominent, and the foundations for stable economic growth still need to be further strengthened." It called for greater efforts to support domestic demand, pointing to the challenge facing authorities in stabilizing growth. These indicators are important to understanding the pressures surrounding stocks, as investors continued to monitor the outlook for stimulus and sources of support for economic activity.

September data showed the composite purchasing managers' index for production at 50.7%, up 1.2 percentage points from the previous month, according to the National Bureau of Statistics. The bureau said the reading indicated an expansion in production and operating activity compared with the previous September. In trading, volumes surged in several large exchange-traded funds tracking the CSI 300, according to the South China Morning Post. The report said the move could point to state-backed purchases aimed at limiting further losses, without asserting that official intervention had taken place. That remains a possibility linked to fund activity, while Thursday's close reflects the scale of the index's decline since its June peak.
