By the end of this lesson you understand what an ETF is, how it tracks an index, and why it's bought and sold like a stock.
\nAn ETF -- Exchange-Traded Fund -- is an investment vehicle that pools many assets into a single product. The most common approach is for an ETF to track a stock market index: instead of trying to individually pick which assets to buy, the ETF buys, approximately, the same assets that make up that index, in similar proportions, so its performance closely resembles that of the full index.
\nThis has a direct practical consequence: buying a single share of an ETF that tracks an index gives you exposure to every company in it at once, instead of having to buy each stock separately -- a single trade, instead of dozens.
\nUnlike other vehicles you'll see in the next module, an ETF trades on an exchange just like a stock: it has a price that varies continuously during market hours, and it's bought and sold using the same order types you've already seen -- market order, limit order -- through your broker.
\nAn ETF that tracks a broad stock market index buys, approximately, the same companies that make up that index, in similar proportions. Buying a share of that ETF gives you exposure to all of those companies at once, without having to buy each stock individually.
\nAn ETF is an exchange-traded fund that pools many assets, typically tracking an index, and it's bought and sold on an exchange just like a stock, in real time during market hours.
\nWhat does it mean for an ETF to "track" an index?
\nWhy can buying an ETF be simpler than buying every stock in an index separately?

\nAn ETF and an index fund can track the same index, but an ETF trades on an exchange in real time, while an index fund is bought and sold once a day at its net asset value.
\nWhy can an ETF sell at a different price at two different points in the same day, while an index fund can't?
\nWhat practical advantage do index funds usually offer over ETFs for recurring contributions?
