The stock market performance may be largely due to the release of new draft regulations by China's securities regulator that hint at positive surprises on audit papers for Chinese companies listed abroad.
The China Securities Regulatory Commission (CSRC) issued an announcement on April 2 that it will revise its regulations on confidentiality and file management for Chinese companies listed abroad, originally issued in 2009, and seek public comments on the new text. The Chinese public has until April 17 to provide feedback.
Most notably, the new regulations will remove the following statement from the previous version:
On-site inspections shall be conducted primarily by Chinese regulators or rely on the results of inspections by Chinese regulators.
The CSRC firmly supports companies to choose their own listing locations according to their own wishes, and the deletion of the above statement is based on the international practice of cross-border audit and regulatory cooperation, it said.
"This reflects the consistent openness of Chinese regulators to cross-border audit and regulatory cooperation and is in line with relevant international practices, and will provide institutional safeguards for the safe and efficient conduct of cross-border regulatory cooperation, including joint inspections," the CSRC said.
From a fundamental perspective, China's major new energy vehicle (NEV) companies all recently reported strong March sales.
Xpeng delivered 15,414 units in March, Li Auto 11,034 units and Nio 9,985 vehicles. BYD sold more than 100,000 NEVs in March for the first time and announced that the company has stopped producing fuel vehicles.
According to a picture shared by a large number of Weibo car bloggers on Sunday, a vehicle suspected to be the new Nio SUV ES7 was seen in a parking lot.
