Guotai Junan and CITIC Securities Involved in Hong Kong Stock Insider Short-Selling Case, ICAC Arrests Several Individuals

===================================================================================================

Introduction: Precise short selling on the eve of rights issues—Hong Kong stock “mouse warehouse” gray industry is about to be uprooted.

In recent days, Hong Kong’s capital market has launched an unprecedented financial anti-corruption storm.

On the evening of March 11, media reports stated that the Hong Kong Securities and Futures Commission (SFC) and the Independent Commission Against Corruption (ICAC) jointly launched a crackdown, targeting senior executives of licensed institutions suspected of insider trading and corruption. The investigation involves Cathay Securities Hong Kong subsidiary, CITIC Securities Hong Kong subsidiary, and hedge fund Wuji Capital. Today, the ICAC announced that it conducted a joint operation codenamed “Fuse” with the SFC on March 10 and 11 to combat suspected insider trading and corruption. Two securities firms, a hedge fund management company, and senior executives are all stakeholders in this case.

This is the largest raid on Hong Kong’s financial industry since 2017.

Incident Related to Rights Issue

During the joint operation, law enforcement officers searched 14 locations, including offices and residences of two securities firms and one hedge fund management company. A total of six men and two women aged between 35 and 60 were arrested. Among them, Pan Jupeng, head of ECM at Cathay Securities International, was the first to be publicly identified as involved.

Today, Cathay Securities International also announced that the company has immediately suspended all operations, duties, and powers of the relevant employees.

Public information shows that Pan Jupeng graduated from the University of Macau with a degree in Business Administration and obtained an MBA from Syracuse University in the United States.

He joined Cathay Securities International in 2015, after working at JPMorgan Chase’s Hong Kong sales and trading department.

Pan Jupeng has long been responsible for IPOs in Hong Kong and the US, GDRs, placements, block trades, and other projects. His recent investigation may be related to placement projects.

Reports indicate that senior management of two licensed securities firms received bribes exceeding HKD 4 million from the head of the licensed hedge fund management company, leaking confidential information about rights issues of multiple Hong Kong-listed companies before official disclosure. This information was supposed to be confidential before public release.

After obtaining these confidential details, the hedge fund management company engaged in short selling related stocks and/or entered into stock short derivative contracts to hedge its positions. When the companies announced rights issues, the stock prices fell, and the hedge fund reportedly profited about HKD 315 million from these short positions.

Market insiders speculate that the ICAC investigation process is likely reverse-traced: first identifying abnormal trades, then targeting the highly profitable funds during that period, following the trail to uncover the “insider.”

Uncovering Wuji Capital

As another involved party, Wuji Capital is a rapidly rising asset management firm in recent years, focusing on “Middle Eastern capital + Hong Kong tech stocks.”

It is known that Wuji Capital is not a newcomer to the Hong Kong market but was founded by former international investment bankers, backed by huge Middle Eastern capital, and deeply engaged in the Asian market. Its development trajectory is highly linked to the recent prosperity of the Hong Kong stock market.

Public records show that Wuji Capital was established in 2015, mainly funded by Middle Eastern sovereign wealth funds, family offices, and other long-term institutional investors. In 2024, it accelerated its deployment in the Hong Kong stock market, and by 2025, it fully expanded, participating in over 15 Hong Kong stock projects with a total investment exceeding HKD 15 billion through a combination of cornerstone investments, exclusive placements, and strategic secondary offerings.

Before this incident, Wuji Capital maintained a high-frequency investment pace. On March 9, 2026, it participated in a HKD 631 million strategic placement of Black Sesame Intelligence, which was its last major Hong Kong stock investment before the case. At that time, it claimed to form long-term strategic cooperation with Black Sesame Intelligence in AI and autonomous driving.

As of now, the list of specific listed companies involved in the investigation has not been disclosed.
