Frequently asked questions
- How often should I rebalance?
- Common approaches are calendar rebalancing (monthly/quarterly) or threshold rebalancing (when any asset drifts more than 5–10% from target). Fees and taxes affect the optimal frequency.
- Why does selling the winner reduce long-term returns?
- Rebalancing is a risk-control strategy, not a return-maximisation strategy. By trimming winners, you reduce volatility and risk, but you also limit upside if the winner keeps running. It is a tradeoff.
