ETFs Explained

How exchange-traded funds work and how to pick one.

1. How ETFs Work — What an exchange-traded fund actually owns, how its price stays close to the value of its holdings, and what to check before you buy your first one.
2. Expense Ratios — How the yearly fee on a fund works, why a fraction of a percent matters so much over decades, and the other hidden costs of owning and trading funds.
3. Sector & Thematic ETFs — How funds that focus on one industry or one big idea work, why their returns spread so far apart, and how to use them without turning your portfolio into a bet.
4. Leveraged & Inverse ETFs — How 2× and 3× funds and inverse funds work, why they reset every day, and a real example of a leveraged fund losing money while its index went nearly nowhere.
5. ETFs vs. Mutual Funds — The real differences between ETFs and traditional mutual funds: how they trade, what they cost, how taxes work and how to decide which fits you.
