In April 2021, an article titled 'You only have a market value of 3 billion, we can't handle it' sparked heated discussions in the market. The article tells the story of a small market value company owner who happens to have an annual report and hopes to further communicate with investors. However, during the roadshow, he was treated with "indifference" from the fund manager: "The company's market value is too small, there is no trading volume, and it is a problem whether it can be sold in the future." From institutions chasing to come to the company for research, to now voluntarily visiting but being rejected, the popularity of small market value companies in the capital market continues to decline. With the implementation of a series of reforms, A-share gradually moves closer to the mature capital market. The reporter of the Securities Times found that the cold phenomenon of A-share companies with small market value has become increasingly apparent and Universal generalization, presenting a "three low" phenomenon: low market attention, low transaction activity, and low utilization rate of capital instruments. For A-share small market value companies facing a downturn in the capital market, several market experts told reporters that referring to the experience of mature capital markets, this is a normal phenomenon. The market is playing the role of survival of the fittest, and various resources are being concentrated towards top enterprises. 46% of listed companies have not received research coverage in the past six months. "Our company has not been interviewed by the media for over a year." When receiving a call from a reporter, a staff member from a small market value company in Zhejiang seemed somewhat surprised. The staff member told the reporter, not only the media, "Our company's last research report on securities firms was in 2015."

Data shows that as of June 16th, the number of A-share listed companies has exceeded 5200, with an average market value of approximately 17.6 billion yuan, but the median market value is only 5.685 billion yuan. Among them, there are 1166 listed companies with a total market value of less than 3 billion yuan, accounting for over 1/5.

That is to say, nearly half of A-share listed companies have not been covered by securities firms' research reports in the past six months.

It should be noted that as of June 16th, there were 1166 listed companies with a total market value of A-shares below 3 billion yuan. This also means that among listed companies with a market value of less than 3 billion yuan, only 187 companies have been covered by securities firms' research reports in the past six months, accounting for less than 20%. The difference is still very obvious. "The staff of the small market value company interviewed by the reporter mentioned above told the reporter," It feels like the company has reached its peak when going public. Since landing in the capital market, the company's market value has exceeded ten billion yuan, and then gradually declined.
