Investor expectations of the company underperforming the broader industry and its shrinking revenues contribute to its low P/S ratio. Shareholders accept this, conceding future revenue probably won't surprise positively.

Shenzhen Yitoa's ROE is weak compared to industry standards. Its five-year net income decline aligns with its low ROE. Despite high reinvestment rate, it's not yielding benefits for investors or boosting earnings growth.

The company's falling revenue is a key factor in its share price drop. A swift return to revenue growth is needed to regain investor interest. Fresh signs of positivity in the past week may indicate a good time for potential investment if business performance steadily improves.
