People invest their money for different reasons, and their motives affect their investments choices. If you are a young adult saving to buy your first house, for example, you probably have a limited amount of capital to invest. You can't afford to gamble on a risky investment or tie your money up for the next 20 years. In contrast, an executive at tile peak of his or her career might be willing to accept more risk and less liquidity. Such a person would select a different mix of investments.
If you're counting on receiving a steady, reasonably predictable flow of cash from your investments, you are chiefly concerned with income. The best strategy would be, to choose bonds, and preferred stocks--that pay dividends or interests on a regular basis. A retired person who wants to supplement Social Security or pension benefits would be a customer for this type of investment.
