Portfolio rebalancing

Restore portfolio exposures toward approved ranges after market, cash-flow or policy changes.

Quick answer

Portfolio rebalancing is the governed process of buying, selling, funding or hedging positions to move exposures toward policy targets. Decisions should account for liquidity, taxes, transaction costs, concentration, currency, private-asset valuations and near-term obligations.
