Rebalancing

What is portfolio rebalancing

Portfolio rebalancing is the process of adjusting the weights of individual assets in an investment portfolio so they match the originally chosen investment strategy and the investor's risk profile. The goal is to keep asset allocation aligned with long-term objectives even as the market values of individual portfolio components change over time.

Why rebalancing matters

• Risk control – without rebalancing, some assets in the portfolio may grow beyond their target weight, thereby increasing overall risk.
• Strategy discipline – keeps investments aligned with the original plan.
• Realizing gains and buying undervalued assets – rebalancing often means selling what has risen and buying what has fallen.
• Psychological discipline – prevents impulsive decisions based on short-term market swings.

How rebalancing is done

• Time-based – carried out at regular intervals (e.g., quarterly, annually).
• Threshold-based – triggered when the weight of a given component exceeds a set threshold (e.g., +/-5% from the target weight).
• Combined – a blend of time-based and threshold-based approaches.

Risks and disadvantages of rebalancing

• Transaction costs – frequent changes can generate fees.
• Tax impact – selling assets can trigger capital gains tax.
• Missed opportunities – reducing the weight of an asset that then continues to grow.
