Exchange-traded funds (ETFs) are not reserved solely for equities; there are also bond ETFs that invest exclusively in fixed-income securities. Investors who want to access relatively low risk corporate bonds can consider investment grade corporate bond ETFs, which buy the high-quality debt of financially strong and stable companies. Examples of the kinds of companies whose bonds are included in these ETFs include Verizon Communications Inc. (VZ), Goldman Sachs Group Inc. (GS), and Wells Fargo & Co. (WFC). These companies have high credit ratings, suggesting a low risk of default. For this reason, these ETFs can provide a strong defensive addition to investment portfolios.
