ETF Investing

What exchange-traded funds are, how they work under the hood, how they differ from index mutual funds, the main types from broad equity to bond to leveraged, and the strategies investors actually build with them.

  1. 1
    What Is an ETF?

    An exchange-traded fund holds a basket of securities and trades all day like a single stock. What ETFs are, where they came from, and why they took over.

  2. 2
    How ETFs Work

    The creation-redemption machinery that keeps an ETF's price glued to its holdings' value — and delivers the transparency and tax efficiency ETFs are famous for.

  3. 3
    Active vs. Passive Investing

    The oldest argument in fund investing — try to beat the market, or own all of it — and why the ETF era has been passive's victory lap. The evidence, honestly.

  4. 4
    ETFs vs. Index Mutual Funds

    An index ETF and an index mutual fund can track the same index at the same cost — the differences are mechanics: trading, taxes, minimums, automation.

  5. 5
    The Types of ETFs

    The ETF menu mapped — broad-market and S&P 500 funds, sector and dividend slices, international exposure, bond ETFs, and one-fund asset-allocation wrappers.

  6. 6
    Leveraged, Inverse & Alternative ETFs

    The exotic shelf — leveraged and inverse ETFs with their daily-reset decay, plus gold, commodity and crypto funds — and why most aren't for holding.

    ETF Investing Strategies

    Putting the pieces together — the one-fund default, core-satellite portfolios, DCA into broad funds, and income sleeves that actually get used.

How to Invest in ETFs

Exchange-traded funds solved a problem investors had complained about for a century: getting broad, cheap, instant diversification without a fortune, a full-service broker, or a fund company's paperwork. One share of a broad-market ETF buys a slice of hundreds of companies, trades in seconds like any stock, and costs a few hundredths of a percent a year to own. That combination is why ETFs went from a curiosity in 1993 to the default building block of modern portfolios, holding trillions of dollars for everyone from first-time savers to pension funds. Learning how to invest in ETFs is, for most people, learning how investing itself is actually done now.

This course covers the instrument from the inside out: what an ETF is and where it came from, the creation-redemption machinery that keeps its price honest, the active-versus-passive argument the ETF era largely settled, how ETFs differ from the index mutual funds they descend from, the full menu of fund types from broad equity to bonds to the leveraged exotics that deserve their warning labels, and the practical strategies — one-fund portfolios, core-satellite, dollar-cost averaging — that put it all to work. The concepts here pair with the live data in our ETF research center, where you can open any fund's complete holdings, sector weights, and valuation and see exactly what these lessons describe. If terms like diversification and asset allocation are new, the Investing Fundamentals course is the natural prerequisite — this course assumes those ideas and applies them.
