📝 Complete Guide to Portfolio Rebalancing in the UK
This portfolio rebalancing calculator UK helps you maintain your target asset allocation. Rebalancing is a disciplined approach to selling high-performing assets and buying underperforming ones, effectively forcing you to 'buy low and sell high'.
💰 What is Portfolio Rebalancing?
Portfolio rebalancing is the process of realigning your investment portfolio back to your target asset allocation. Over time, different assets grow at different rates, causing your portfolio to drift from its original allocation.
- Example: Target 60% equities, 40% bonds
- After 5 years: Equities grow to 75%, Bonds to 25%
- Action: Sell equities, buy bonds to restore 60/40
📊 Why Rebalancing Matters
