Why didn't Di Wei's stock rise for a long time?

The main reason why Di Wei's stock has not risen for a long time is that the company's profits have fallen. Di Wei Co., Ltd. is mainly engaged in the business related to auto parts and electronic products. In recent years, its profits have been declining and there is no new growth point. And it does not belong to the scientific and technological innovation sector, and the premium given is not high. The company's current dynamic P/E ratio is as high as 900 times, which shows that the company's growth is weak, which is also the reason why Di Wei shares do not rise.
