What caused CATL to overtake PetroChina in market value again, and what were the key drivers behind CATL's recent stock surge?

CATL overtook PetroChina in market value due to investor enthusiasm for green energy amid geopolitical tensions, particularly following the outbreak of the Middle East conflict. Its shares surged—up to 6.7% in Shenzhen and 11% in Hong Kong—driven by better-than-expected quarterly profit and a strategic plan to expand into critical minerals. This propelled CATL’s market capitalization to a record 2.1 trillion yuan ($306 billion), reinforcing its position as China’s third-largest onshore stock. The rise coincided with heightened investor interest in CATL’s energy storage business, seen as pivotal to reducing fossil fuel dependence. In contrast, PetroChina’s market value retreated as crude oil prices eased amid ceasefire talks and regulatory moves to cap fuel price hikes to protect consumers.

How does CATL’s current market standing compare to China’s largest state-owned enterprises, and what does Bloomberg Intelligence say about the reasons for its strong performance?

CATL now ranks as China’s third-largest onshore stock, trailing only the nation’s two biggest state-owned banks—but ahead of PetroChina, the country’s largest oil and gas producer. Bloomberg Intelligence analysts Joanna Chen and Jason Zhao attributed CATL’s strong performance to a confirmed 'storage boom' and the company’s structural advantages in cost control, stemming from its large-scale operations and operational efficiency. These factors, combined with its expanding role in energy storage and critical minerals, have solidified investor confidence and driven its market valuation upward.
