Investors' expectations of the company's strong revenue growth outperforming the broader industry likely explain the high P/S ratio. If recent medium-term revenue trends persist, a significant share price drop seems unlikely.

YanTai LongYuan Power Technology's high P/E ratio is concerning due to limited recent growth. Investors hope for a business turnaround, but without significant improvement, the high P/E ratio may not be sustainable. The recent earnings decline could heavily impact the share price.
