Index funds are one of the most common ways people start investing, but they can be confusing at first because terms like ETF, S&P 500, VOO, VTI, mutual fund, Roth IRA, and brokerage account all get mixed together.

In this video, I explain what index funds are, how they work, how they are different from actively managed funds, and why many investors use them for long-term investing. I also cover the difference between index funds and ETFs, common examples like S&P 500 funds and total stock market funds, how expense ratios work, how investors make money with index funds, and the biggest mistakes to avoid.

This video is for education only and is not financial advice. I am not recommending that you buy or sell any specific investment. The goal is to help you understand the basics before putting real money into the market.

This video is for anyone trying to understand index funds, ETFs, S&P 500 investing, total market funds, and long-term investing in a simple way.

Clarification: In the video, I mention FXAIX as an example of an S&P 500 index fund. FXAIX is Fidelity’s S&P 500 index mutual fund, not an ETF like VOO, SPY, or IVV. Depending on the broker app you use, FXAIX may not be available directly. The main point is that these are examples of funds designed to track the S&P 500, but the exact funds available can vary by platform.
