Key Terms

regulation (eu) no 596/2014, 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 regulations regulatory

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

A set of laws and rules designed to stop cheating and unfair tactics in financial markets, such as trading on secret information or manipulating prices. For investors, these regulations matter because they protect fair prices and confidence—like traffic laws that keep drivers honest so everyone can rely on the road—reducing the risk that market moves are driven by hidden or dishonest behavior rather than genuine supply and demand.

designated person regulatory

"notification of share transaction by a Designated Person (i.e. Directors..."

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.
