Despite Tongding Interconnection Information's recent share price rise, its low P/S ratio may reflect market skepticism about its future revenue performance. The company's shrinking medium-term revenue, against an industry set to grow, could continue to hinder share price growth.

Investors may believe Tongding Interconnection Information's revenue growth will underperform the industry, causing a low P/S ratio. The company's shrinking revenue and the industry's projected growth could lead to a further drop in P/S. If these trends persist, the share price may remain stagnant.
