You answer a few goal-oriented questions that determine your preferred investment strategy and overall risk tolerance. Than the robo-advisor uses math and algorithms to invest your contributions across a mix of US stocks, foreign stock, emerging markets, municipal bonds and dividend growth stocks. It's a set-it-and-forget it long term strategy for those who plan to keep money in the market for the long haul. I also like that it automatically handles dividend reinvestment and tax-loss harvesting. Very user friendly interface that is connected to my bank account. I can either move cash into Wealthfront's high interest yielding cash account or into the investment account I mentioned above, with the click of a button in my app.
