A Person Discharging Managerial Responsibilities — PDMR — is the UK and EU regulatory term for someone senior enough at a listed company that their share dealings have to be made public. It covers the board, and it also covers senior executives who aren't directors but who have regular access to inside information and the authority to take decisions affecting the company's future.
The category exists because the job title isn't the point. A divisional chief executive who sees the numbers before the market does is in the same position as a main-board director, whatever the org chart says, so the rules follow the access rather than the label. People closely associated with a PDMR — spouses, dependent children, and companies or trusts they control — are caught too, for the obvious reason.
When a PDMR buys or sells shares in their own company, the transaction has to be notified promptly and then announced publicly. That announcement is what this site is built on: it is the moment a private decision becomes a public fact.
The disclosure tells you what happened, not why. A PDMR buying is a person with better information than you choosing to increase their exposure with their own money — which is interesting — but the same filing format covers purchases made for entirely mechanical reasons, which is why distinguishing an open-market buy from everything else matters more than the headline.
