Passive ETF
Also known as: index ETF, passively managed ETF
A passive ETF is an exchange-traded fund that tracks a market index, such as the S&P 500, rather than trying to beat it. It trades on an exchange throughout the day and typically carries low expenses.
A passive ETF is an exchange-traded fund designed to replicate the performance of a benchmark index — the S&P 500, a bond index, a sector index — rather than outperform it. Instead of paying managers to pick securities, the fund simply holds the index's components in matching proportions, so its returns closely mirror the index minus a small fee.
Like all ETFs, passive ETFs trade on an exchange throughout the day at market prices, so investors can buy and sell them any time the market is open, use limit orders, and even sell them short. This intraday liquidity contrasts with mutual funds, which are priced and traded only once per day at net asset value (NAV).
Because there is no active management to pay for, passive ETFs typically have low expense ratios. Their creation and redemption mechanism — large institutions exchanging baskets of the underlying securities for ETF shares in kind — keeps market prices close to NAV and tends to make them tax-efficient, since the fund can satisfy redemptions without selling holdings and realizing capital gains.
Passive ETFs appear on the SIE, Series 6, and Series 7 exams within the investment companies material. Know how they differ from mutual funds (intraday exchange trading versus once-daily NAV pricing), how they differ from actively managed ETFs, and why their costs and tax profiles tend to be favorable.
