Analysis of CATL (03750.HK) Trending on Hong Kong Stock Market

CATL (03750.HK) appeared on the Eastmoney App Hong Kong stocks hot list at 2025-12-25 16:30:01 UTC+8, coinciding with Christmas Day when the Hong Kong Stock Exchange (HKEX) was closed. This means the “hotness” reflects pre-holiday news and investor sentiment rather than real-time trading activity. As the world’s leading lithium battery manufacturer (energy storage devices sector), CATL’s market cap stood at 23,046 billion HKD based on its latest H-shares closing price (505.00 HKD on 2025-12-19). Key news catalysts driving its popularity include a 10-year supply agreement with major automakers (securing long-term demand), progress in its Jianxiawo lithium mine development (enhancing raw material security), and expansion into emerging markets like low-altitude economy and humanoid robots [1].

The A-shares counterpart (300750.SZ) serves as a sentiment proxy since HKEX was closed. From 2025-12-22 to 2025-12-25, A-shares traded between 371.84 and 378.10 CNY with stable volume (20.34M-25.49M shares/day), closing at 373.01 CNY on Christmas Day (down 0.32%) [0]. The energy storage devices sector also showed a 1.02% average increase around the same period, supporting CATL’s momentum [1].
