ETF Glossary FAQ
Which ETF terms should beginners learn first?
Start with ETF, expense ratio, NAV, premium or discount, tracking error, dividend yield, and rebalancing.
Why does ETF expense ratio matter?
The expense ratio is deducted from ETF assets each year. Over long periods, even small fee differences can compound into meaningful return gaps.
How should I read NAV and premium or discount?
NAV is the fund’s net asset value. Premium or discount shows how far the market price is from NAV, which matters when buying or selling.
Why is rebalancing needed in ETF investing?
ETF prices move and target weights drift. Rebalancing brings the portfolio back to the intended risk mix.
