Zhejiang Yuejian Intelligent EquipmentLtd's declining ROCE and sales, along with increased capital employment, are worrisome. Despite this, the stock has risen 3.7% in the last three years, suggesting investor optimism. Current trends, however, do not inspire confidence in the company's investment potential.

Despite slower growth, the company's P/S ratio aligns with the industry, indicating investor interest. However, if medium-term revenue trends persist, a significant share price drop is likely. Weak revenue and slower growth could adjust the P/S ratio to meet expectations.
