bonds investment grade bonds are issued by stable companies with a low risk of default and therefore have lower interest rates than non investment grade bonds non investment grade bonds also known as junk bonds or high yield bonds have lower credit ratings due to a probability of default by the issuer investors receive a higher interest rate from investing in junk bonds for assuming the higher

credit rating agenciesfixed income securities usually have less price volatility than stocksu s treasury fixed income securities are backed by the full faith and credit of the united states governmentthe issuer can default on making the interest payments or paying back the principalfixed income securities typically have a lower rate of return than many other investments including

securityfixed income securities provide steady interest income to investors reduce risk in an investment portfolio and protect against volatility or fluctuations in the market equities are traditionally more volatile than bonds so investors may allocate a portion of their portfolios to fixed income investments to reduce their risk level fixed income securities are also available in mutual funds and exchange traded funds etfs the prices of bonds and fixed income securities increase and decrease although the interest payments of fixed income securities are steady their prices are not guaranteed to remain stable throughout the life of the holding if investors sell a fixed income security before maturity gains or losses are based on the difference between the purchase price and the sale price besides the risk of price fluctuations bonds also have the risk of a potential default u s government bonds are considered incredibly low risk as they are backed by the full faith and credit of the united states government 2 corporate bonds depend on the financial viability of a company and have a higher risk of default than government bonds however corporate bonds have a good chance to be repaid if a company declares bankruptcy since bondholders will be repaid before common and even preferred stockholders fixed income securities commonly have low returns and slow capital appreciation or price increases this is the trade off for lower risk their prices tend to decrease slower as well the initial principal amount is often inaccessible particularly with long term bonds with maturities greater than ten years however the bond can be sold to get the investment back early if the current market value is equal or greater to the amount invested fixed income securities provide a fixed interest payment regardless of where market interest rates move an investor that purchased a bond paying 2 per year will lose out on income if market interest rates rise above that level and the investor s money is tied up in the 2 bond this is also what causes a decline in the market price of bonds if rates rise above the bond s interest rate its market value declines inflation may erode the return on fixed rate securities if the inflation rate is higher than the interest rate of the fixed income instrument all bonds have credit or default risk since the securities are tied to the issuer s financial viability investing in international bonds can increase the risk of default if the country is economically or politically unstable real world exampletreasury bonds are long
