ETF vs Mutual Fund

ETF vs Mutual Fund — Which Is Better in 2026?

Both can track the same index (S&P 500, total market). The choice matters most for tax efficiency in a taxable brokerage account.

Verdict

For taxable accounts, ETFs win every time on tax efficiency (no forced capital-gain distributions). For 401(k)s and Roth IRAs, the wrapper doesn’t matter; pick the lowest expense ratio.
