Who just crossed 5%?
When anyone — family offices, activist funds, sovereign wealth, famous CEOs buying into other companies — crosses a 3–5% voting- rights threshold in an EU or UK listed company, they must disclose it within 2–4 trading days. A different signal from Article 19 PDMR filings — conviction across the table, not inside one.

Why this signal matters
A CEO buying €1m of their own stock is confidence. A family office quietly accumulating 5% of a small listed industrial is conviction across the table — and often a leading indicator of an activist campaign, a take-private bid, a sovereign wealth allocation, or a cornerstone investment. Academic literature (Brav, Jiang, Kim 2010 on activism; Bebchuk et al 2013) consistently finds substantial outperformance in the months following 13D / equivalent filings in the US. Europe's Transparency Directive is the European equivalent.
