Xiong'an New Power TechnologyLtd may be overvalued due to its high P/S ratio, unsupported by recent revenue performance. The company's poor growth rate could lead to future disappointment for shareholders if the P/S ratio falls to levels more in line with the recent negative growth rates.

Despite poor growth, Xiong'an New Power TechnologyLtd trades at a high P/S, suggesting investor hopes for a business turnaround. However, continued revenue decline could impact share price negatively, indicating potential overvaluation.
