Anhui Ankai Automobile's low P/S ratio may be due to investors' belief that its revenue growth might underperform the broader industry. The company's shrinking revenue and shareholders' acceptance of low P/S suggest future revenue won't provide any pleasant surprises.

The company's unprofitability and low revenue growth may have led to a 28% stock decline over the past year. Long term investors have seen a 3% annual return over five years. The recent sell-off could be a chance if long term growth trend signs emerge.

Investors hope for a turnaround in the company's business prospects despite poor growth. However, unless medium-term conditions improve, the share price may not be seen as fair value. Continuation of recent revenue trends could impact the share price.
