Key Concepts to UnderstandFive things that drive ETF performance more than anything else
Net Assets (AUM)
Total money the ETF manages. Larger AUM usually means tighter bid-ask spreads and lower closure risk. ETFs under $50M are sometimes liquidated by the issuer.
Learn more →NAV
Net Asset Value, the per-share value of everything the ETF owns minus what it owes, calculated end-of-day. The trading price can drift slightly above (premium) or below (discount) NAV during the day.
Learn more →Tracking Error
How closely the ETF's returns match its benchmark. Index ETFs aim for near-zero tracking error; high tracking error in an index fund usually signals fees, sampling, or poor management.
Learn more →Total Return
Capital gain + reinvested dividends. The headline price chart only shows the price part, total return is what you actually pocket, and is the only fair way to compare ETFs across asset classes.
