Every investigation is assessed on its own facts, with advice tailored to the evidence, the applicable law and your individual circumstances.
Insider dealing involves trading, or encouraging another person to trade, while in possession of inside information that is not publicly available and could significantly affect the price of financial instruments if disclosed. These investigations often concern listed company shares, corporate transactions, market-sensitive announcements, mergers and acquisitions and confidential commercial information.
The evidence frequently includes telephone records, emails, messaging applications, trading data and financial analysis.
Market abuse covers a broad range of conduct capable of undermining confidence in financial markets. Investigations may involve allegations concerning insider dealing, unlawful disclosure of inside information, market manipulation, misleading trading activity, false or misleading market signals, benchmark manipulation and regulatory reporting failures.
The FCA has extensive investigatory powers and may pursue regulatory action, criminal proceedings or both, depending on the circumstances.
The Financial Conduct Authority has significant powers to investigate suspected misconduct. An investigation may include:
Compulsory requests for documents
Interviews
Production notices
Analysis of trading records
Digital evidence
Financial analysis
Cooperation with overseas regulators
The decisions made during the earliest stages of an investigation can have a significant impact on the outcome. Obtaining legal advice before responding to the FCA can help protect your legal position and ensure your rights are preserved.
Depending on the nature of the allegations, an investigation may result in:
Regulatory enforcement action
Financial penalties
Prohibition orders
Public censures
Criminal prosecution
