What if a computer built and managed a sensible investment portfolio for you, for a fraction of a human advisor's fee? That's a robo-advisor.
Not everyone wants to pick funds or pay a human advisor thousands. Robo-advisors fill that gap: software that builds, manages, and rebalances a portfolio for you, for a tiny fee. For hands-off investors, they're a genuinely useful middle ground.
— Educational, not financial advice.
