CATL (03750.HK) Hong Kong Stock Hot List Analysis: Index Inclusion and Market Performance

The event occurred at 10:30:01 on December 25, 2025 (UTC+8), Christmas Day, when the Hong Kong Stock Exchange was closed. Therefore, the hot list popularity reflects market dynamics on December 24 or earlier [1]. The core background is that CATL (03750.HK) was included in the FTSE China 50 Index and took effect on December 22, which usually attracts passive capital inflows to support the stock price [2]. Market data shows that the Hong Kong stock rose 8.19% in the past 20 days [0], reflecting investors’ positive response to the inclusion event; however, its A-share (300750.SZ) closed at $370.34 on December 24, falling 1.40% on the same day [0], reflecting differences in market sentiment or capital structure between AH shares.

1. Sustained Impact of Index Inclusion
   : Inclusion in the FTSE China 50 Index will bring sustained passive capital inflows, enhance stock liquidity, and support the stock price in the long term [2].
2. Underlying Logic of AH Share Divergence
   : Hong Kong stocks have a high proportion of foreign capital and are sensitive to events like index inclusion; A-shares are dominated by domestic capital, so short-term fluctuations are more susceptible to emotional influences [0].
3. Persistence of Event Influence
   : Still ranking on the hot list on a closed day indicates high market attention to the FTSE inclusion event, and the influence has not weakened with the market closure [1].

• Opportunities
  : Passive capital inflows from index inclusion may further push up the Hong Kong stock price and increase the company’s market attention [2].
• Risks
  : Need to be alert to market volatility risks, especially the linkage impact of A-share performance on Hong Kong stocks; at the same time, the capital inflow effect after inclusion may gradually weaken [0].
• Priority
  : Short-term focus on capital trends after the inclusion takes effect, long-term judgment combined with the company’s fundamentals.
