Red-chip firms are those incorporated overseas but operate in the mainland, with a great number of Chinese issuers in the US falling in this category. Previously, red-chip firms had no access to domestic public equity markets but the door has opened after a slew of reform measures since 2018.

Qualified red-chip firms, even with special ownership arrangements like weighted voting rights or variable interest entity, are now allowed to get listed in the mainland, via the issuance of stocks or Chinese Depository Receipts or CDRs, which represent the issuers' shares.

The Wuxi-based China Resources Microelectronics Ltd debuted on Shanghai's STAR Market in February as the first red-chip company that made an IPO in the mainland bourses, followed by the stock issuance of SMIC, which also operates as a red-chip company.

The first CDR issuance was made by Ninebot Ltd in Shanghai in October. The Beijing-based robot maker is not only a red-chip company but adopts a variable interest entity structure.

The Shenzhen Stock Exchange is expected to catch up with Shanghai in the issuance of CDRs, as the central government released a document in October that encourages overseas-incorporated innovative companies to issue CDRs in Shenzhen on a pilot basis.

On the other hand, valuation differences will also encourage a lot more US-listed Chinese firms to head for the A-share market and receive a higher valuation. The pathway could be to go private first and then seek a re-listing domestically, with the red-chip structures maintained or removed on a case-by-case basis.

Despite that large-cap new-economy Chinese enterprises receive high valuations in US stock markets, small and medium-cap ones are poorly valued compared with mainland markets, especially Shanghai's STAR Market and Shenzhen's ChiNext board.

At a time when the capital market has become a core link in China's dual-circulation development pattern, the re-listing of Chinese firms in the A-share market has assumed greater significance than ever.

It would not only unfold strategic investment opportunities for investors but help optimize the structure of listed firms and strengthen the competitiveness of the A-share market.

Investors are expected to be excited about the potential comeback of Chinese issuers, and speculative trading may be triggered in the short term.

In a longer-term perspective, however, investors will gradually value the shares rationally in comparison with similar ones listed in Hong Kong, the US, and other markets around the world, a process that will narrow the valuation differences of Chinese issuers among different listing venues.

It is a great achievement for the mainland stock markets to complete rule revamps in only three years to embrace the re-listings from overseas listed issuers, as part of the broader IPO reforms to spur innovation.

But more efforts are needed when it comes to enhancing the efficiency of public companies' re-financing channels and mergers and acquisitions. The A-share market still lags behind its US and Hong Kong counterparts in this aspect, despite recent policy relaxations.

It is also worth noting that though the re-listings may provide more quality investment targets for A-share investors, it is still advisable for the governments from both sides to cooperate and resolve the audit dispute, preventing political forces from intervening in market issues.

After all, Chinese issuers have become important components of the US equity markets, taking a considerable share in daily trading volume. Whether the Chinese issuers will continue to exist and develop themselves in the US markets would be one of the signs of whether the US will continue to be at the heart of the global stock markets.
