On the evening of April 3rd, the A-share market experienced a regulatory storm. Overnight, 10 listed companies were investigated and punished, which is not only a fluctuation in numbers, but also a strong signal for the regulatory authorities to comprehensively upgrade their strict investigation situation.

If we shift the timeline forward for just two days, from April 1st to 3rd, the total number of listed companies investigated and fined has reached 13 within just three days. Among them, 6 have been initiated for investigation, 3 have been issued with advance notice of administrative penalties, and 4 have been issued with administrative penalty decision letters.

This thunderous enforcement force clearly sends a signal to the market: regulatory pressure has become the norm, and any attempt to cross the bottom line will have nowhere to hide.

Misleading statements have become a top priority in strict investigation

In this wave of punishment, a significant new regulatory trend is that "misleading statements" have become the top priority of strict investigation.

Whether it is accurate hype of "self questioning and self answering" through the SSE e-interactive platform, exaggerated publicity on WeChat official account, or false description in investor relations activities, as long as it involves market hot concepts and information distortion, it will face the double punishment system of "company+key minority".

Taking Yingjixin as an example, it made a high-profile claim on the e-Interactive platform that it had entered the field of brain computer interface chips, deliberately concealing differences in technical paths and exaggerating product sales status. As a result, it was fined 4 million yuan and several executives were heavily punished.

Shuangliang Energy Saving, through its WeChat official account, scraped the "commercial aerospace" hot spot, exaggerated the proportion of order amount and the level of cooperation, misled investors, and was also severely punished. This indicates that the regulatory perspective has extended from legal disclosure platforms to all channels such as social media, and any attempt to mislead the market through "borderline tactics" will pay a heavy price.

The regulation of financial fraud also leaves no blind spots and exhibits the characteristic of "zero tolerance". The regulatory authorities have made it clear that financial fraud is indiscriminate, and both inflated and reduced profits will be treated equally.

Shandong Zhanggu used the rare technique of "reverse financial fraud" by inflating expenses to achieve a low profit of 8.46 million yuan, which ultimately led to the company being issued other risk warnings and fined 2.5 million yuan. Several executives were also fined.

In addition, Hengxin Oriental mistakenly used the total amount method to recognize revenue without control, inflating operating revenue by 182 million yuan, and was also heavily fined by ST. Even more severe is that * ST Guandian was already punished for fund occupation and illegal guarantees in 2025, but on April 3, 2026, it was once again investigated for suspected illegal information disclosure. This deeply demonstrates that fund occupation and illegal guarantees are not a one-time punishment, and continuous accountability and in-depth investigation are the norm of regulation.

The accountability chain has been extended

It is worth being highly vigilant that the regulatory accountability chain has extended to after delisting.

R Yishang 1, which was delisted in 2023, was still fined 7 million yuan on April 3, 2026. In fact, the controller was fined 10 million yuan and subjected to a 7-year market ban.

This case is extremely shocking: regardless of how long it has been or whether it is still in the A-share market, regulators will investigate to the end, and delisting is not a safe haven for illegal activities.

At the same time, some hidden violations were equally fatal: the actual controller of Beismei increased his holdings to 32.37%, failed to fulfill his tender offer obligations and did not disclose them, and was fined 4.5 million yuan; Intercontinental Oil and Gas shareholders' reduction of holdings has reached the 5% red line without suspension, fined 1 million yuan; The actual controller of Xianhe Shares is suspected of short-term trading by borrowing someone else's account to hold shares, and even if he resigns, he cannot escape accountability. These cases warn the market that compliance is not a multiple-choice question, but a mandatory one.

From the data of the first quarter, it is evident that there is a trend of comprehensive regulatory acceleration. According to statistics, in the first quarter, securities and financial regulatory authorities issued nearly 300 "fines" to listed companies and related responsible persons, involving about 170 listed companies and 20 investigations, a significant increase year-on-year.

The process from filing to punishment has been significantly shortened, for example, Shuangliang Energy Saving was filed 15 days after the violation letter was issued, and Rongbai Technology received a prior notice only 19 days from filing to receiving it. Regulation is shifting from "post accountability" to "pre prevention" and "in-process control", building a comprehensive and three-dimensional accountability system.

During the National People's Congress and Chinese People's Political Consultative Conference, Wu Qing, Chairman of the China Securities Regulatory Commission, emphasized the need to "strictly investigate and punish hot topics, speculative concepts, and manipulation in accordance with the law." The concentrated punishment on April 3rd is an acceleration of this high-pressure situation.

Building an ecosystem of 'dare not violate, cannot violate, and do not want to violate'

Behind this regulatory storm is the firm determination of the regulatory authorities to purify the market ecology and promote high-quality development of the capital market.

In the whole year of 2025, the regulatory authorities investigated and dealt with 701 cases of securities and futures violations, with a total fine of 15.47 billion yuan. A group of market manipulators were fined exorbitant prices, and some cases have been transferred to the public security organs for criminal responsibility.

The 2026 system work conference will further clarify the main line of "stability first, quality improvement and efficiency enhancement", and seriously investigate and punish excessive speculation and market manipulation. The goal of regulation is not to suppress the market, but to break down the gray chain of "cutting leeks", protect the interests of small and medium-sized investors, and promote the transformation of the market from "capital speculation driven" to "value performance driven".

With the implementation of precise measures such as the increase in financing margin ratio and the suspension verification of popular concept stocks, the A-share market is undergoing a profound structural reshaping.

In the face of an increasingly severe regulatory environment, all parties in the market must soberly realize that there is no turning point when riding on hotspots, and there is no safe haven for illegal activities. For listed companies, truthful, accurate, and complete information disclosure is the bottom line, and any financial fraud, fund occupation, or illegal guarantee behavior will be severely punished; For investors, they should firmly stay away from the concept of speculative stocks without performance support, be alert to potential risks during market adjustment periods, and adhere to the concept of long-term investment and value investment.

This regulatory storm is not only a clearing of past chaos, but also a safeguard for the healthy development of the future market. A more fair, transparent, and standardized A-share market is gradually taking shape in the "long teeth and thorns" of regulation.

The regulatory authorities once again emphasized through the "Ten Punishments in One Night" Thunder Action that there is no turning point in riding on hot topics, and there is no safe haven for illegal activities. Compliance is no longer an option, but a necessary question for the survival and development of all listed companies. With the normalization of delisting and the improvement of the lifelong penalty tracing mechanism, A-shares are accelerating the construction of an ecosystem of "dare not violate, cannot violate, and do not want to violate", laying a solid foundation for investors' rights and the long-term healthy operation of the market.
