wunder beta📈 Index Funds, Explained
The boring investment that quietly beats most of the experts.
What you’ll learn
- Define an index fund and explain why its low cost and passive approach tend to outperform active managers.Index funds track an index like the S&P 500, owning the whole market cheaply. Jack Bogle launched the first one in 1976. Low fees and SPIVA data show most active funds underperform over the long run.
- Distinguish index funds from ETFs and explain how diversification, compounding, and patience drive results.Index mutual funds and ETFs both track indexes but trade differently. Broad diversification cuts single-company risk, and decades of steady, hands-off contributions let compounding do the work.
