Assets Under Management
Basics
どういう意味か
The total market value of all the assets that an investment fund (like an ETF or mutual fund) manages. Larger AUM generally means the fund is more stable, popular, and liquid.
例
VOO has over $1 trillion in AUM, making it one of the largest ETFs in the world. A tiny ETF with only $10 million in AUM may have liquidity issues.
初心者がよくやるミス
Beginners think "bigger AUM = always better." While very small AUM can indicate liquidity risk, huge AUM is not always an advantage. For niche strategies, smaller funds can be more flexible.
