Sany Heavy Industry's stock plummeted 5.24% during intraday trading on Monday, extending a recent selloff.

The decline was primarily driven by the company's first-quarter earnings report, which revealed a significant divergence between revenue and profit growth. While revenue increased by 14.22% year-over-year, net profit attributable to shareholders grew a mere 0.46%, raising serious concerns about margin compression within the construction machinery sector.

Further pressure came from broader sector weakness, with peer Zoomlion also reporting a substantial year-over-year decline in net profit. Additionally, institutional funds were observed net selling shares during prior rally sessions, intensifying the correction pressure on Sany Heavy Industry and contributing to the day's sharp decline.
