What a robo-advisor is, and what it isn't

Automated portfolio management is a real service with a real cost. It is not the same as financial advice.

The short answer

  • A robo-advisor allocates and rebalances a portfolio using rules driven by an onboarding questionnaire.
  • You pay a platform fee on top of the underlying fund charges.
  • Regulatory duties differ by jurisdiction and by whether the service is advisory or discretionary.

A robo-advisor builds and maintains a portfolio for you using software. You answer questions about goals, time horizon and tolerance for loss; the platform maps the answers to a model portfolio, usually of index funds or ETFs, and then keeps that allocation on target as markets move.

What the service actually does

  • Asset allocation from a questionnaire-driven risk profile.
  • Automatic rebalancing when weights drift from target.
  • Automated deposits and fractional investing.
  • In some markets, tax-aware features such as loss harvesting or account-type placement.

The two-layer cost

There is the platform's management fee and, separately, the ongoing charges of the funds it buys. Both are deducted from your money. A low platform fee paired with expensive in-house funds is not necessarily cheaper than the reverse, so the number that matters is the total.

Who it suits

Automated management is most useful for straightforward, long-horizon investing where the main risks are inertia and poor diversification. It is a weaker fit for complex situations — concentrated stock positions, cross-border tax, business assets, estate planning — where a human specialist can consider facts the questionnaire never asks about.
