A robo-adviser is a highly advanced computer algorithm that helps you to invest your money. Depending on the settings and the type of Robo-adviser you use, they sometimes invest automatically, or at your request.
Most of these Robo-advisers use algorithms to find safe stocks that will help grow your portfolio. Some of them will then invest an allocated amount automatically, where others will require you to do it manually.
They’re a great way for beginners to get started investing because they often require very little money and they do most of the work for you. That’s not to say you shouldn’t keep eyes on your account — this is your money; you never want to be completely hands-off — but a Robo-advisor will do the heavy lifting.
