Major Chinese oil companies including China Petroleum & Chemical Corp. and PetroChina issued investor warnings Tuesday about risks stemming from recent stock price gains. The firms emphasized that short-term oil price volatility remains highly uncertain, with no major changes to industry policies or company operations despite market turbulence.

The warnings followed a surge in energy shares triggered by knock-on effects from the war in Iran, including surging oil prices and disruptions in energy shipments through the Strait of Hormuz. China's CSI 300 Energy Index jumped approximately 15% over the past two trading sessions, significantly outperforming the broader market.

This divergence comes as energy stocks rally while the broader onshore equity benchmark index lost more than 1% during the same period. The 15% gain in energy stocks reflects investor concerns about supply chain disruptions amid geopolitical tensions in the Middle East.

The cautious tone from state-owned oil giants suggests they see current valuations as disconnected from underlying fundamentals, potentially signaling a correction as the Iran conflict's impact on global oil markets continues to unfold.
