Zhejiang Huada New Materials' low P/E ratio may be due to expectations of degrading strong earnings performance. The company's recent medium-term earnings decline is also contributing to its low P/E. The low P/E and declining earnings may continue to weigh on the share price unless conditions improve.

The decreasing returns on capital for Zhejiang Huada New Materials suggest the business might be losing its competitive edge or market share. The increased capital usage and reduced sales are concerning, which is likely why the stock's value has declined.
