Despite Chongqing Sanxia Paints' share drop, its high P/S ratio could worry investors. Poor three-year revenue trends and high P/S ratio may suggest an unsustainable share price. Without medium-term improvements, the share price may be deemed unreasonable.

Chongqing Sanxia Paints' modest 0.3% dividend yield isn't supporting its share price. Despite a 13% loss in shares over the year, long-term investors may still see potential with a 3% annual return over five years.
