Conservative investors prefer debt instruments not only because they safeguard the capital invested but also for the regular income flows they provide. Bonds bring a great deal of stability to an equity-heavy portfolio while providing dividends more frequently than individual bonds. U.S government bonds funds usually invest in Treasury bills, notes and securities issued by government agencies. They are considered to be the safest in the bond fund category and are ideal options for the risk-averse investor.
