An index fund is a passively-managed fund that tracks a particular index, such as the Standard and Poor's 500 (S&P 500), which means they seek to track the performance of the underlying index rather than trying to outperform it.
Investing in the S&P 500 is made easy with IVV, which has an expense ratio of just 0.03%, making it a low-cost option. The annual costs come to about $3 for a $10,000 investment, which is cost-effective compared to actively managed funds, which can charge up to 1%.
QQQM is a market capitalization index with 101 of the largest non-financial sector stocks trading on the Nasdaq Stock Exchange. The Nasdaq 100 is more volatile than the S&P 500, meaning that it has higher risk and the potential for higher returns.
