For those who prefer a more do-it-yourself style but still want their investments to be managed automatically, a robo-advisor like Betterment may be better suited. After completing an initial questionnaire, this program will automatically invest your money based on things like your risk tolerance and time horizon. They’ll even rebalance your portfolio when necessary – all automatically, of course!

In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
