Shenzhen Strongteam Decoration Engineering's high P/E ratio is alarming considering its recent poor growth. If medium-term earnings trends persist, it could greatly affect the share price. The current high P/E ratio may not be sustainable given the company's recent earnings performance.

Despite a high P/E ratio, shrinking medium-term earnings and underperformance against market forecasts suggest a risk of share price decline. This could pose a significant risk to shareholders and potential investors might be overpaying.
