Why ETFs are bad

ETFs are tools, and whether they're "bad" depends on how they're used. Broad, low-cost index ETFs are often simple and efficient. But some ETFs can be problematic if investors treat them like guaranteed winners or ignore what's inside.

Common downsides include hidden trading costs (spreads), buying illiquid or tiny ETFs that may close, and using complex products like leveraged or inverse ETFs without understanding how daily resets and compounding work.

The biggest risk is often behavioral: because ETFs are easy to trade, it's easy to overtrade, chase themes, and switch strategies at the wrong times. If you stick to transparent, diversified ETFs and trade thoughtfully, many of these issues shrink dramatically.
