In late September 2026, Chinese stock markets briefly interrupted a three-day losing streak. The Shanghai Composite Index rose 0.18 percent to 3,830.45, supported by the resource, agricultural, and utility sectors, while the Shenzhen Composite Index increased 0.41 percent to 2,410.04.

By late October, the market entered a period of significant decline, losing US$3.5 trillion in value since its peak in May. This downturn pushed the onshore CSI 300 Index into a bear market following a 20% decline from its June high. Investor pessimism is driven by weakening corporate earnings and a protracted consumption slump, with third-quarter results for many companies missing consensus estimates by an average of 9%.

Sector-specific struggles are evident in the technology and automotive industries. The STAR50 index has declined by approximately 40% in less than four months. Specifically, the Hang Seng Tech Index has seen profit projections fall by more than 13% since late March, while MSCI China constituents have seen 2026 earnings forecasts cut by over 4%. Major companies, including battery giant CATL, China Mobile, and Ganfeng Lithium, have reported earnings below expectations due to fierce competition and weak demand. Analysts note a lack of significant new government stimulus, as policymakers appear to be managing the economic deceleration at a “tolerable pace.”
