In plain English: this page lists every stock Ron Baron'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).

Total return (dividends included)
Read these numbers carefully: “Reported value change” is the change in the total value of the shares on this manager’s 13F — it is not the fund’s investment return. The total also moves when investors put money into the fund or take it out, and a 13F covers only long US-listed shares — no shorts, bonds, cash or foreign stocks — so the fund’s actual return can be higher or lower.

Not investment advice. Hypothetical, not actual results. 13F filings arrive up to 45 days after quarter end, so anyone copying them buys late; the top-10 figures start the day after each filing was published. Reported value changes include deposits and withdrawals and are not the fund's return. Costs, taxes and positions without price data are ignored. Past performance does not predict future results.
