AUM

Assets Under Management (AUM) is the total market value of the investments a mutual fund holds on behalf of all its investors. It changes daily with market movements and inflows/outflows.

A larger AUM usually means a more established fund with better economies of scale (lower expense ratios), but very large AUMs can also hurt — equity funds with ₹50,000+ crore AUM find it hard to take meaningful positions in mid-cap or small-cap stocks without moving the price.
