The following table lists the top 100 largest exchange-traded funds, ranked by assets under management (AUM). The AUM of an ETF is calculated by multiplying shares outstanding by the market price per share. An ETF’s assets will fluctuate based on both changes in the value of the underlying securities and the creation of new shares or redemption of existing shares. It is worth noting that there may be a difference between an ETF’s market capitalization and the net asset value (NAV) of its underlying securities. The difference results in either a discount or a premium in the trading price of the ETF.
