Instead of buying lots of individual bonds, you can buy a bond ETF to diversify among many bonds and leave the selection to the ETF managers. Bond ETFs come in many different varieties including government, corporate, short-term, long-term, junk, municipal, international and in variations and combinations of each type. Like most investments, higher yields mean higher risk. So choose your bond ETFs based on your risk tolerance, asset type, and liquidity.


Residual income is calculated as net income less a charge for the cost of capital. The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
