Setting price limits (usually ±10%) is mainly to curb excessive speculation, prevent drastic short-term fluctuations, protect small and medium investors, and maintain market stability.

Reasons:

1. Curb speculation: Limiting extreme price fluctuations in a single day reduces market manipulation and herd behavior risks.

2. Buffering risks: Providing investors with a cooling-off period to avoid irrational trading caused by panic or frenzy.

3. Protecting retail investors: With a high proportion of retail investors in the Chinese stock market, price limits reduce sudden losses due to information lag.

4. Market stability: Smoothing the price discovery process and preventing liquidity depletion or the spread of systemic risks.
