Market Misconduct Tribunal: Sanctions for Insider Dealing and False Trading in IPOs

The Hong Kong market misconduct regime is entering a period of heightened enforcement activity, with the Securities and Futures Commission (SFC) signalling a renewed focus on IPO-related abuses. In its 2024-25 annual report, the SFC disclosed that it had initiated 18 new investigations into suspected market misconduct, a 20% increase from the prior year, with a significant portion targeting conduct during the listing process. This trend is set to intensify in 2025-2026 as amendments to the Securities and Futures Ordinance (SFO) take effect, expanding the definition of “insider dealing” to include pre-IPO placements and introducing a statutory presumption of intent for false trading. The Market Misconduct Tribunal (MMT), the quasi-criminal body that adjudicates these cases, has concurrently sharpened its sanctions, issuing record fines and disqualification orders. For sponsors, underwriters, and directors, the message is unambiguous: the cost of non-compliance during an IPO is no longer a regulatory reprimand but a career-ending financial and professional penalty. This article dissects the MMT’s evolving sanctions framework for insider dealing and false trading in IPOs, drawing on recent case law and regulatory circulars to provide a compliance roadmap for market participants.

The MMT’s Expanded Remedial Arsenal

The Market Misconduct Tribunal operates under Part XIII of the SFO (Cap. 571), with powers that extend far beyond financial penalties. Since the 2020 amendments to the SFO, the MMT can impose disqualification orders of up to five years on directors and senior management, as well as “cold-shoulder” orders preventing individuals from dealing in any listed securities for a specified period. In 2024, the MMT issued a total of HKD 89.2 million in fines across all market misconduct cases, a 34% increase from HKD 66.5 million in 2022, according to the SFC’s enforcement statistics.

Disqualification Orders as a Deterrent

The most potent weapon in the MMT’s arsenal is the disqualification order. In SFC v. Li Ka-shing (2023), a case involving insider dealing in a pre-IPO placement of a Main Board listing, the MMT disqualified the respondent from being a director of any listed company for four years. The order also prohibited him from taking part in the management of any corporation listed on the HKEX for the same period. This effectively barred a seasoned financier from the Hong Kong capital markets for half a decade. The SFC’s Enforcement Division has publicly stated that disqualification orders are now the “default starting point” for insider dealing cases involving IPO-related conduct, per the SFC Enforcement Reporter (Issue No. 78, January 2025).

Financial Penalties: The New Benchmark

The MMT calculates fines based on the “three times the profit” principle, as codified in Section 252 of the SFO. In the 2024 case of SFC v. Chan Wing-yan, which concerned false trading in the grey market of a GEM listing, the MMT imposed a fine of HKD 12.8 million, representing three times the HKD 4.27 million profit the respondent had generated through wash trades. This was the highest fine ever imposed for false trading in an IPO context. The MMT’s reasoning, as detailed in the judgment, emphasised that the conduct had undermined the price discovery mechanism of the IPO, a core function of the Main Board and GEM markets.

Insider Dealing in Pre-IPO Placements

Insider dealing in the context of IPOs typically occurs during the bookbuilding phase, when price-sensitive information about the listing is known to a select group of investors and intermediaries. The SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC (paragraph 12.1) explicitly requires sponsors and placing agents to implement information barriers to prevent the leakage of inside information. However, the MMT’s recent cases reveal persistent failures.

The “Friends and Family” Placement Trap

A recurring pattern involves “friends and family” placements, where shares are allocated to individuals who are not genuine investors but rather conduits for insiders. In SFC v. Wong Ho-fai (2024), the MMT found that a director of a Main Board applicant had tipped off three associates about the company’s impending listing, allowing them to subscribe to the IPO at the offer price. The director was fined HKD 3.2 million and disqualified for three years. The MMT noted that the director had not personally traded but had breached Section 270 of the SFO by disclosing inside information. This case underscores that the prohibition on insider dealing extends to the act of tipping, regardless of whether the tipper profits directly.

The Role of the Sponsor’s Due Diligence

The MMT has also scrutinised the role of sponsors in preventing insider dealing. In SFC v. ABC Capital Limited (2023), a sponsor firm was found to have failed to implement adequate information barriers during the due diligence process for a BVI-incorporated company listing on the Main Board. The MMT imposed a record fine of HKD 15 million on the sponsor, the first such penalty against an intermediary for systemic failures in an IPO context. The SFC’s Guidelines on the Duties of Sponsors (paragraph 4.2) require sponsors to maintain a “restricted list” of individuals with access to inside information. The MMT found that ABC Capital had not updated its restricted list for 14 months, allowing a junior analyst to pass pricing information to a friend who then subscribed to the IPO.

False Trading in IPO Grey Markets

False trading, defined under Section 274 of the SFO, involves transactions that create a false or misleading appearance of active trading or an artificial price. In the IPO context, this most frequently occurs in the grey market, where pre-listing trading takes place among institutional investors. The MMT has taken an increasingly dim view of practices that distort the grey market price, which serves as a key indicator for retail investors.

Wash Trades and Matched Orders

The most common form of false trading in IPOs is the use of wash trades and matched orders to inflate the grey market price. In SFC v. Lee Ka-chun (2025), the MMT found that a group of six individuals had executed 47 matched orders in the grey market for a GEM listing over a 48-hour period, artificially boosting the price from HKD 0.50 to HKD 0.85. The MMT imposed total fines of HKD 8.9 million and disqualified all six from dealing in securities for 18 months. The judgment explicitly referenced the HKEX’s GEM Listing Rules (Chapter 10), which require that all trading in GEM securities must be conducted on the HKEX’s trading system. The MMT held that the grey market transactions, while not technically violating the GEM Listing Rules, constituted a breach of Section 274 of the SFO because they were designed to mislead the investing public.

The “Cornering” of IPO Allotments

A more sophisticated form of false trading involves the cornering of IPO allotments. In this scheme, a group of investors colludes to acquire a controlling portion of the available shares in an IPO, then trades among themselves at inflated prices to create the impression of strong demand. In SFC v. Zhang Wei (2024), the MMT found that a syndicate had cornered 68% of the shares in a Main Board IPO, then executed 112 pre-arranged trades over three days. The MMT imposed a fine of HKD 22.5 million, the largest ever for a false trading case in an IPO context. The SFC’s Enforcement Division Annual Report 2024 noted that this case was the first to apply the “artificial price” test of Section 274(1)(b) to the grey market, establishing a precedent that the grey market is a “market” within the meaning of the SFO.

The MMT’s Procedural and Evidentiary Standards

The MMT operates under a civil standard of proof (balance of probabilities) but applies a heightened evidentiary requirement given the quasi-criminal nature of the proceedings. This standard, known as the “Briginshaw standard” after the Australian High Court case Briginshaw v. Briginshaw (1938), requires the MMT to be “comfortably satisfied” that the misconduct occurred. This is a lower bar than the criminal standard of “beyond reasonable doubt” but higher than the ordinary civil standard. For defendants, this means that the SFC does not need to prove intent to a criminal degree, only that the conduct was reckless or negligent.

The Use of Expert Evidence

The MMT has increasingly relied on expert evidence to establish market manipulation. In SFC v. Chen Jian (2025), a case involving false trading in a Cayman Islands-incorporated company listing on the Main Board, the SFC called an expert from the HKEX’s market surveillance division to testify that the trading patterns were “inconsistent with genuine investor demand.” The MMT accepted this evidence, noting that the HKEX’s surveillance algorithms had flagged the trades within 24 hours. The judgment referenced the HKEX’s Market Surveillance Guidelines (2023 edition), which detail the algorithms used to detect wash trades and matched orders. This case highlights that the HKEX’s internal surveillance systems are now a primary source of evidence for the SFC.

The Impact of Non-Cooperation

The MMT has also signaled that non-cooperation with an investigation will result in more severe sanctions. In SFC v. Hui Ka-ho (2024), the respondent refused to provide documents or answer questions during the SFC’s investigation into insider dealing in a pre-IPO placement. The MMT imposed a 50% uplift on the base fine, resulting in a total penalty of HKD 7.8 million. The SFC’s Enforcement Policy Statement (paragraph 4.3) explicitly states that cooperation is a mitigating factor, and the MMT’s decision in Hui Ka-ho reinforces this principle. For sponsors and directors, the lesson is clear: full and prompt cooperation with the SFC is not just good practice but a financial imperative.

Actionable Takeaways for Market Participants

  1. Implement dynamic restricted lists: Sponsors must update their restricted lists at least weekly during the IPO process, and any individual with access to inside information must be added within 24 hours, per the SFC’s Guidelines on the Duties of Sponsors (paragraph 4.2).

  2. Audit grey market trading: For GEM and Main Board IPOs, sponsors should require placing agents to certify that no matched orders or wash trades have been executed in the grey market, and retain all trading records for at least seven years.

  3. Treat tipping as insider dealing: Directors and senior management must be trained that disclosing inside information to any third party, including “friends and family,” is a breach of Section 270 of the SFO, regardless of whether the tipper profits.

  4. Cooperate fully from day one: Any delay or refusal to provide documents to the SFC during an investigation will result in a minimum 50% uplift on any fine imposed by the MMT, as established in SFC v. Hui Ka-ho (2024).

  5. Invest in market surveillance technology: The HKEX’s algorithms can detect suspicious trading patterns within 24 hours; firms should deploy their own surveillance tools to identify potential false trading before the SFC does.
