Despite Kunming Chuan Jin Nuo Chemical's recent share price surge, its P/S ratio remains below industry median, possibly due to doubts over its ability to sustain recent revenue performance. However, if medium-term revenue trends persist, price risks seem minimal.

Kunming Chuan Jin Nuo Chemical's poor performance has led to negative market sentiment. However, recovery could present an opportunity for investors. The company's underperformance may be due to market jitters. Investors should consider the risk and ensure they're investing in a high-quality business.
