Key Concepts and Summary

All investments can be categorized according to three key characteristics: average expected return, degree of risk, and liquidity. To get a higher rate of return, an investor must typically accept either more risk or less liquidity. Banks are an example of a financial intermediary, an institution that operates to coordinate supply and demand in the financial capital market. Banks offer a range of accounts, including checking accounts, savings accounts, and certificates of deposit. Under the federal deposit insurance program, banks purchase insurance against the risk of a bank failure.

A typical bond promises the financial investor a series of payments over time, based on the interest rate at the time the bond is issued, and then repayment of what was borrowed. Bonds that offer a high rate of return but also a relatively high chance of defaulting on the payments are called high yield or junk bonds. The bond yield is the rate of return that a bond promises to pay at the time of purchase. Even when bonds make payments based on a fixed rate of interest, they are somewhat risky, because if interest rates rise for the economy as a whole, an investor who owns bonds issued at lower interest rates is now locked into the low rate and suffers a loss.

Changes in the price of a stock depend on changes in expectations about future profits. Investing in any individual firm is somewhat risky, so investors are wise to practice diversification, which means investing in a range of companies. A mutual fund purchases an array of stocks and/or bonds. An investor in the mutual fund then receives a return depending on the overall performance of the investments made by the fund as a whole. A mutual fund that seeks to imitate the overall behavior of the stock market is called an index fund.

Housing and other tangible assets can also be regarded as forms of financial investment, which pay a rate of return in the form of capital gains. Housing can also offer a nonfinancial return—specifically, you can live in it.
