China Stock Market: CSI 300 Loses 8.5% as Sell-Off Deepens

What happened

China's CSI 300 fell 8.5% in October, extending a losing streak to 12 straight weeks with a 15% drop over that period. Selling continued into November despite fresh measures from Beijing to stabilise the market, as investors retreated from technology shares.

Confirmed

Global impact / market context

Falling share prices reduce the cash companies can raise by selling new stock, which can slow spending on factories, equipment and research. Technology firms that rely on rising valuations to fund growth face tighter options, and households holding shares feel poorer, which may reduce spending.

Analyst inference

The drop reflects doubts about whether heavy spending on AI infrastructure, semiconductors and computing capacity will earn enough profit. The STAR 50 technology index is down about 40% from its late-June peak, wiping out roughly $480 billion in value, showing how concentrated the selling is in tech.

Analyst inference

What to watch

1. The CSI 300's losing streak has reached 12 consecutive weeks, falling 15% over the period, and selling continued into November despite Beijing's fresh market-stabilising measures. Confirmed
2. Watch how Beijing's stabilising measures are designed and funded, since details would show whether they add real buying demand or mainly aim to slow the decline in share prices. Proposed
3. Track whether selling spreads from semiconductors and communications equipment into other sectors, because a broader decline would point to weaker company profits and reduced investment spending ahead. Analyst inference
