Dongfang Electric's stock price plummeted 5.01% during intraday trading on Friday, reflecting significant selling pressure.

The sharp decline is attributed to market concerns over the sustainability of the company's earnings. While its recently disclosed Q1 results showed a 37.41% year-over-year increase in headline net profit, the core profit growth—excluding non-recurring items—was only 11.49%. This substantial gap indicates a heavy reliance on one-time gains, raising doubts about the quality and durability of its earnings.

Furthermore, the stock was weighed down by broad weakness in the Heavy Electrical Equipment sector and a notable reduction in institutional holdings. Citigroup recently decreased its long position in Dongfang Electric H-shares, which contributed to the downward momentum amid the sector-wide sell-off.
