Diamond Hill Investment Group manages a substantial multi-billion-dollar portfolio of assets across its comprehensive suite of mutual funds, exchange-traded funds (ETFs), and institutional separate accounts. The exact total of Assets Under Management (AUM) fluctuates continuously in real-time, driven by daily stock market performance, net institutional capital inflows or outflows, and dividend reinvestments. Precise, up-to-date AUM figures are reported publicly at the conclusion of each fiscal quarter through official corporate earnings releases and SEC Form 10-Q filings available on investor relations portals.
