Nanjing Sunlord Electronics' low P/S ratio may be due to anticipated continued or accelerated disappointing revenue performance. If recent medium-term revenue trends persist, a share price reversal seems unlikely.

Nanjing Sunlord Electronics' declining ROCE trend is worrying, indicating potential loss of competitive edge or market share. The rise in current liabilities also poses risks. Given these factors, it's recommended to avoid this stock for now.

Though Nanjing Sunlord Electronics has been reinvesting in its business, the dwindling returns are a concern. Despite the stock gaining 39% over the last year, if these underlying trends persist, the company might not deliver substantial returns going forward.
