In plain English: this page lists every stock Chuck Royce's fund told the SEC it owned at the end of the quarter, biggest first, and what changed since the quarter before — "New" means they bought it for the first time, "Sold" means they sold all of it. The list is at least 6 weeks old, and it is only part of their investments (no cash, bonds or bets against stocks).
