Shares of Chaowei Power Holdings Ltd (00951.HK) plunged 5.37% during Thursday's intraday trading following the release of its annual financial results. The sharp decline reflects investor disappointment with the company's performance for the fiscal year.

According to the financial report, Chaowei Power posted a gross margin of 6.9%, which investors may view as relatively low for the industry. The company reported a net income attributable to shareholders of RMB 290 million and basic earnings per share (EPS) of RMB 0.26. While the company achieved substantial revenue of RMB 50,341 million, the low profitability metrics seem to have overshadowed this figure.

Despite the challenging financial performance, Chaowei Power announced a final dividend of HKD 0.043 per share. However, this appears to have done little to assuage investor concerns, as evidenced by the significant stock price drop. The market reaction suggests that investors may have been expecting stronger results or are concerned about the company's future prospects given the current financial indicators.
