Shanghai Hugong Electric Group's high P/S ratio is alarming due to its falling revenue. Unless conditions improve, the share price may keep dropping. Investors should be wary as the current share price may not represent fair value.

The falling ROCE and sales, coupled with high capital investment, could signal a company trying to grow but losing market presence. These indications may affect the long-term stock performance, potentially warranting investor search for alternatives unless a reversal occurs.
