Despite Hebei Jianxin Chemical's high P/S ratio and declining revenue, the market is optimistic about its future performance. However, with the industry's expected growth of 27% next year, the company's share price may decrease if performance doesn't improve significantly.

Hebei Jianxin Chemical's investments underperform due to a drop in share price and revenue in the past five years. Despite recent gains and dividends easing some losses, its past performance and current financial state warrant caution.
