Shanghai Highly (Group)'s P/S ratio remains below industry median despite recent share price surge. The company's disappointing revenue trends over the past three years contribute to this. Shareholders accept the low P/S, anticipating no future revenue surprises.

Investors expect less impressive future growth from the company compared to the industry, hence the low P/S ratio. No significant surge in the share price is projected if current revenue trends continue.

Shanghai Highly (Group) has a five-year total shareholder return loss of 1.2% per year, and the sudden drop in EPS raises questions about the sustainability of its share price increase. The cautionary tone in the overall assessment suggests it might not be an ideal buy now.
