Calculation and mechanics
Net assets follow from the market value of the securities and cash held minus liabilities. Divided by the number of shares outstanding, this gives the net asset value (NAV) per share.
Net assets change with the prices of the positions held and with inflows and outflows when fund shares are created or redeemed.
A standardised public source for many US ETFs is the NPORT-P filing with the SEC. The publicly available filing currently refers to the quarter end and appears with a time lag. It is well suited for the size of a fund, for a same-day value the fund provider's figures are more current.
Net assets = assets - liabilities
Distinction
Net assets are not the same as the liquidity of an ETF. A large fund can be traded relatively little, while smaller ETFs can also be liquid. Trading volume and bid-ask spreads give more direct clues about how easily an ETF can be traded.
The contents of a fund do not follow from its size either: two ETFs with similar net assets can hold completely different positions.
