What to Check

Check index methodology, holdings, creation and redemption process, bid-ask spread, premium or discount, tracking difference, leverage or inverse reset terms, and tax treatment.

Common Mistakes

  • Assuming an ETF always trades exactly at NAV.
  • Ignoring bid-ask spread, tracking difference, and creation-redemption mechanics.
  • Holding leveraged or inverse ETFs without understanding reset behavior.
  • Treating a familiar ETF brand as a substitute for reading the fund objective.
