Fixed income
Fixed income refers to any type of investment that yields a regular (fixed) payment. For example, if you borrow money and have to pay interest once a month, you have issued a fixed income security. When a company does this, it is called a bond (although 'preferred stock' is also sometimes considered to be fixed income).The term fixed income is also applied to people's income which are invariant each period. This could include income derived from fixed income investments such as bonds and prefered stocks or pensions that guarantee a fixed income.
Fixed income securities can be contrasted with variable return securities such as stocks. To understand the difference between stocks and bonds, you have to understand a company's motivation. A company wants to raise money, and it doesn't want to wait until it has gotten enough through regular operations (selling stuff). To get money in a capitalist society, you always have to give something in return. The company can either pledge a part of itself, by giving equity in the company (stock), or the company can give a promise to pay regular interest and borrow the money (bond).
While a bond is simply a promise to pay interest on borrowed money, there is some important terminology used by the fixed income industry:
- The principal of a bond is the amount that is being lent.
- The coupon is the interest that will be paid.
- The maturity is the end of the bond, the date that the amount must be returned.
- The issuer is the entity (company or govt.) who is borrowing the money (issuing the bond) and paying the interest (the coupon).
- The issue is another term for the bond itself.
- The indenture is the contract that states all of the terms of the bond.
Interest rates change over time. For example, if a company wants to raise $1 million and not a lot of people in the market have free cash to lend, the company will have to offer a high rate of interest (coupon) to get people to buy their bond. If there are a lot of people in the market trying to get a return on their money, the company can offer a lower coupon.
To complicate matters further, fixed income securities are actually traded on the open market, just like stocks. To understand this, first realize that bonds are usually traded in certain amounts, for example $100,000. If you want to receive 7,000 a month and the going interest rate is only 6%, you will have to pay a premium to get the amount you want. Likewise, if you only need 5,000 a month, you can get that bond at a discount.
