AUM
Assets Under Management is the total market value of the investments a fund or manager holds.
AUM signals scale and liquidity. Very large small-cap AUM can make it harder for a manager to enter or exit positions without moving prices, while very small AUM can mean higher per-unit costs.
Why AUM matters when comparing products
Assets Under Management (AUM) is an important metric for Indian investors to consider as it reflects the size and potential operational implications for a fund. A substantial AUM can indicate investor confidence and economies of scale, potentially leading to lower expense ratios. However, for strategies like small-cap funds, an excessively large AUM might challenge a fund manager's ability to execute trades efficiently without impacting market prices, affecting performance. Conversely, very low AUM could lead to higher per-unit operating costs for the fund.
Illustrative example
Consider two hypothetical small-cap equity funds in India. Fund A has an AUM of ₹5,000 crore, while Fund B has an AUM of ₹50 crore. When Fund A's manager buys or sells shares in a less liquid small-cap stock, the large transaction value might noticeably affect the stock's price. Fund B's manager, with a smaller AUM, might find it easier to enter or exit positions in such stocks without causing significant price movements, potentially offering more agility.
