We are preparing new stock market guides for this section. Browse the other sections in the meantime.

An ETF or index fund holds many securities in one purchase, which spreads risk compared with a single stock. That is a benefit, not a guarantee: funds can and do lose value, particularly when the market they track falls.

These guides cover how funds are built, how to compare expense ratios and tracking, what the major index funds contain, and how dividend funds differ. No fund is presented as safe or certain to profit.
