BYD ELECTRONIC shares surged 5% during intraday trading on Wednesday, extending gains after earlier rising 3.11% in regular trading. The stock hit 23.94 HKD as turnover neared 39.81 million HKD.

The rally was fueled by the recent filing and approval of a liquid cooling heat sink components project in Shantou. The project, with an annual capacity of 800,000 liquid cooling plates, represents a concrete step into the AIDC liquid cooling domain, leveraging the company's automotive thermal management expertise. This move is seen as a new growth driver beyond its core electronics manufacturing.

China Post Securities maintained a Buy rating on BYD ELECTRONIC, projecting revenue growth and highlighting the liquid cooling business as a key catalyst. The broker noted that the broader liquid cooling sector is transitioning from expectations to order and earnings delivery, further boosting investor sentiment.
