The declining ROCE and the increase in current liabilities are not positive signs for ZHEJIANG NARADA POWER SOURCE. These trends suggest that the company may be facing increased competition or smaller margins, and may not be a good investment prospect.

Despite recent gains, the company's long-term performance shows unresolved challenges, underperforming the broader market. Future prospects are uncertain with identified warning signs for investors.

The low ROE despite high debt usage is concerning. Investors should consider the company's performance in less favorable credit markets. High-quality businesses usually have high ROE and low debt.

ZHEJIANG NARADA's P/S ratio trails behind industry peers even with robust revenue growth. The market seems uneasy about its future income stability, possibly affecting its P/S ratio and belief in its growth prospects.

The continued ROCE decline and stable capital show that ZHEJIANG NARADA POWER SOURCE's growth has stalled over the past five years, signaling a possible worrying future. If these trends persist, investors may not see significant returns.

Despite ZHEJIANG NARADA POWER's promising revenue growth, the declining share price suggests expectations exceeded the actual growth. This could present a buying opportunity, but keep an eye on the company's fundamentals and associated risks.
