Key Terms

regulation (eu) no 596/2014, market abuse (market abuse regulations), designated person

3 terms

regulation (eu) no 596/2014 regulatory

"Article 19(3) of Regulation (EU) No 596/2014 of the European Parliament..."

A European Union law that sets rules to prevent insider trading and market manipulation by requiring timely public disclosure of confidential company information that could affect share prices, and by governing trades by company insiders and communication rules. It matters to investors because it helps keep markets fair and transparent—like a rulebook and referee for trading—so prices reflect publicly available facts and investors can trust markets are not being rigged by people with secret information.

market abuse (market abuse regulations) regulatory

"on market abuse (Market Abuse Regulations), ArcelorMittal announces..."

Market abuse describes illegal or unfair actions—such as trading on secret information, spreading false or misleading rumors, or manipulating prices—that distort how securities are bought and sold. Market abuse regulations are the laws and rules that forbid those actions and set penalties to stop them. They matter to investors because they help ensure prices reflect real supply and demand, protect everyday and professional investors from cheating, and maintain trust in the market much like referees keep a game fair.

designated person regulatory

"notifications of share transactions by a Designated Person (i.e. Directors or Executive Officers)..."

A designated person is an individual or entity officially named to carry out specific duties or act on behalf of a company for legal, regulatory or communication purposes — think of them as the company’s appointed point person for a particular task. For investors, knowing who is designated matters because that person has the authority to receive official notices, make filings, handle compliance or speak for the company, which can affect how quickly issues are resolved and who is accountable if problems or insider-information questions arise.
