FUNDTracks a broad index of United States investment grade bonds.
iShares Core U.S. Aggregate Bond ETF is an exchange traded fund. Tracks a broad index of United States investment grade bonds. A fund like this holds many securities in one package, so an investor gets broad exposure to US investment grade bond market through a single holding. It trades on NYSE Arca like a stock during market hours. Funds charge ongoing fees and their value can rise or fall with the markets they track, so reading the fund documents is a good first step.
It follows an index of US investment grade bonds. That includes US Treasury bonds, bonds backed by home mortgages, and bonds issued by companies with solid credit ratings. A bond is a loan you make to a government or company in return for interest and your money back later.
Bond prices and interest rates move in opposite directions. When rates go up, existing bonds that pay less become worth less, and the fund price can dip. The reverse is also true. A number called duration tells you roughly how sensitive the fund is to rate changes. Look for it on the fund page.
Investors often use a bond fund to balance out stocks, since the two do not always move together. It is not risk free. It can lose value in some years, and the income it pays changes over time. The goal for many people is steadiness, not high returns.
Why do bond prices fall when rates rise?
New bonds pay more, so older ones that pay less are worth less to buyers.
Is this safer than stocks?
Usually calmer, but not guaranteed. Check how it did in past years.
What is investment grade?
