China's CSI 300 Enters Bear Market After 10-Week Rout

China's CSI 300 fell 20% from its June peak as the Hang Seng Tech index dropped as much as 5.3%, with AI profitability doubts and weak consumption weighing.

Lead

China's CSI 300 index slid into a bear market on Thursday, October 22, closing 1.8% lower and extending its losses from the June peak to 20%. The benchmark, which tracks 300 of the largest stocks listed in Shanghai and Shenzhen, has now declined for 10 consecutive weeks and trades at its lowest level in 15 months. Across financial markets today, the move marks a sharp reversal for one of the year's most closely watched equity rallies, driven by a slump in household spending and growing doubts over whether artificial intelligence companies can turn investment into earnings.

What Happened in Chinese Stocks on Thursday?

The CSI 300 closed down 1.8%, the session that pushed its drawdown from the June high to the 20% threshold that conventionally defines a bear market. The 10-week run of weekly declines is the longest in the index's history.

Hong Kong fell in step. The Hang Seng Tech index dropped as much as 5.3% during the session, its largest intraday decline since July 17. By midday the broader Hang Seng index was down 2.9%, while the technology gauge was lower by 4.6%.

The selling spread beyond China. Equities across Asia weakened as the technology sell-off deepened, though mainland and Hong Kong shares bore the heaviest losses. The rout in onshore shares has erased roughly $2.4 trillion in market value from the recent peak, leaving Chinese equities among the worst performers globally this year.

Why Are Chinese Stocks Falling?

Chinese stocks are falling because of two overlapping pressures: weak domestic consumption and fading confidence that AI spending will pay off.

On the consumption side, a protracted slump in household demand has weighed on retailers, consumer brands and platform companies. Growth is barely meeting official targets, and the absence of a broad-based stimulus package has disappointed investors who had positioned for larger fiscal support. Competition across several industries has also eroded margins, slowing corporate profit growth.

On the technology side, the AI trade that lifted Chinese equities earlier in the year has lost momentum. Investors are increasingly asking when heavy spending on models, chips and data centers will translate into sustainable revenue. That question has pressured the large internet and hardware names that dominate the Hang Seng Tech index.

Why Did the Hang Seng Tech Index Drop So Sharply?

The Hang Seng Tech index fell sharply because regulatory and business challenges facing China's e-commerce industry compounded the broader AI and consumption concerns. Large platforms, including Alibaba Group Holding (BABA), were among the heaviest drags on the gauge during the session.

E-commerce companies are directly exposed to both themes at once. Their core retail businesses depend on household spending, while their cloud and AI units carry the investment burden that markets now scrutinize. When both sides come under pressure, the index absorbs the loss quickly, and the 5.3% intraday decline reflected that concentration.

Market Structure and Positioning

A 20% decline over 10 weeks without a single weekly gain points to persistent, one-directional selling rather than a short, sharp shock. Bear market territory also tends to change behavior. Funds that track drawdown limits may reduce exposure, and retail participation typically cools after prolonged losses.

The scale of the loss is notable against the backdrop earlier in the year, when the same index was near its highs. A $2.4 trillion drop in market value also narrows the wealth effect for Chinese households with equity holdings, which can feed back into the consumption weakness that helped start the decline.

What Comes Next for China's Stock Market?

The near-term path depends on three variables: policy, earnings and the global AI narrative.

• Policy: A broad spending package aimed at households would address the consumption gap directly. Its absence has been a central source of disappointment, so any shift in tone from Beijing carries outsized weight for sentiment.
• Earnings: Upcoming corporate reports will show whether margin pressure is easing or spreading, and whether AI investment is producing revenue growth.
• Global technology sentiment: Chinese technology shares remain tied to the wider debate over AI valuations, which has also unsettled U.S. and Asian markets.

For global investors, the bear market raises questions about China's weight in emerging-market allocations and the durability of growth that is barely meeting official goals. For Chinese policymakers, a falling equity market complicates efforts to stabilize confidence.

Outlook

The CSI 300's entry into a bear market after a record 10-week losing streak, together with a 5.3% intraday slide in the Hang Seng Tech index, shows how far sentiment toward Chinese equities has shifted since June. Weak consumption and unproven AI profitability remain the central drivers. Whether the selling stops depends on a more forceful policy response, evidence of improving corporate earnings, and steadier global appetite for technology shares.
