Why ETFs are down today

The best way to answer this kind of ETF question is to separate the ETF wrapper from the exposure inside it. ETFs can hold many different asset classes and can be passive or active, so the right conclusion depends on what the fund owns and how it's managed.

If you're evaluating an ETF, focus on holdings (or the benchmark it tracks), fees, liquidity (bid-ask spread), and how it fits with what you already own. That checklist prevents most common mistakes.

If you want a quick sanity check, compare a few similar ETFs side-by-side on holdings and cost, then decide based on fit rather than marketing labels.
