How Robo-Advisors Manage Risk and Taxes
- Modern Portfolio Theory (MPT): Platforms determine your risk tolerance through an introductory questionnaire, allocating assets across uncorrelated asset classes (domestic equities, international equities, fixed income) to maximize return per unit of volatility.
- Automated Rebalancing: When a rally in equities skews your original 80/20 equity-to-bond ratio to 88/12, the platform automatically trims equities and purchases bonds to restore your target allocation without requiring manual trades.
- Tax-Loss Harvesting (TLH):In taxable accounts, algorithms monitor positions for unrealized losses, selling them to offset taxable capital gains while simultaneously buying correlated substitute funds to preserve market exposure.
