The choice to use index funds rather than actively managed funds is a significant one. Index funds tend to be rather straightforward, easy-to-own, and cost-effective investment vehicles. But, just like actively managed funds, index funds also have their differences that investors should be aware of.
Cost Still Counts. Different index funds can charge different fees. Funds that are otherwise virtually identical (meaning they track the same index) can nonetheless produce different returns based on their fees, because fund fees are deducted from returns. This cost difference can have a significant effect on fund performance when compounded over time.
The Challenges of Tracking an Index. Tracking error is the degree to which an index fund fails to mirror its benchmark's performance during a given time period. As the components and weightings of an index change over time, the fund must buy and sell holdings in an attempt to match it, and some funds may do this better than others.
Subtle Index Differences. Index funds within the same category may not track the same index. Consequently, two index funds that may sound very similar could actually have very different portfolios and performance numbers.
The investment return and principal value of mutual funds will fluctuate and shares, when sold, may be worth more or less than their original cost. Mutual funds are sold by prospectus, which can be obtained from your financial professional or the company and which contains complete information, including investment objectives, risks, charges and expenses. Investors should be read the prospectus and consider this information carefully before investing or sending money.
