Portfolio Rebalancing: The Complete Guide for Retail Investors

Portfolio rebalancing is the single most underrated investing discipline. Most retail investors set a target allocation once, then let the market decide their actual allocation.

What Is Portfolio Rebalancing?

Bringing your portfolio back to target allocation. If you target 60% stocks and 40% bonds, and the market pushes you to 75/25, rebalancing means selling stocks and buying bonds.

Why Rebalancing Matters

• Risk control — your risk profile changes as allocations drift
• Disciplined selling — forces you to take profits on winners
• Forced buying — naturally buys low and sells high
• Emotional anchor — prevents panic selling during corrections

Three Rebalancing Strategies

1. Calendar-Based

Pick a date — quarterly or semi-annually — and rebalance regardless of market conditions. Simple, automatic, no monitoring needed.

2. Threshold-Based

Set a drift threshold (typically 5%). When any asset class exceeds it, rebalance. More precise but requires monitoring.

3. Hybrid Approach

Light calendar rebalance quarterly + full rebalance when threshold is hit. Best for most serious retail investors.
