Qingdao Doublestar's low P/S ratio may reflect investor expectations of underperforming revenue growth. With continued limited growth rates, a reversal in share price seems unlikely.

The company's lacklustre revenue growth and unprofitability may have led to the share price drop. Its performance, worse than the annualised loss of 4% over the last half decade, may indicate unresolved challenges. Long term share price weakness could be a bad sign, but contrarian investors might see a potential turnaround.

Investors predict the continuation of the company's lackluster growth rates, as suggested by the low P/S ratio. The share price won't likely see a turnabout unless current revenue trends change. This has resulted in a low price-to-sales ratio, undershooting industry expectations.
