By understanding the 30-day yield and how that information can be extrapolated to longer-term yields, bond fund investors have a better chance of getting the outcomes they expect. Bond funds, of course, are subject to the same ebbs and flows of economic pressures as other investments but tend to be fairly stable assets overall.

If you're considering a bond fund, the 30-day yield is just one of many items to consider. Always evaluate the prospectus and make sure you understand the fees involved with investing in a particular bond fund before you commit.
