When and How to Rebalance Your Portfolio?

Rebalancing your portfolio is a key part of effective investment management. It ensures that your investment allocation changes to reflect your goals and risk tolerance. There are two main approaches to rebalancing: threshold-based and time-based. In this article, we will explore both approaches and also discuss the integration of tax-loss harvesting, while leveraging our QMA Portfolio Health Check to assess your portfolio.

Threshold-Based Rebalancing (5/25 Rule)

One of the most common approaches is threshold-based rebalancing, which usually involves setting certain thresholds for individual investments. For example:

• 5/25 Rule: If the percentage allocation of a particular stock in your portfolio deviates by more than 5% from the target weight, or if the stock's weight exceeds 25% of the total portfolio, it’s time to rebalance.

Example: If you have a portfolio with a target allocation of 60% stocks and 40% bonds, and one stock, for instance, AAPL, increases to 30%, it would be appropriate to sell a portion of AAPL and reinvest in bonds to maintain the target allocation.

Advantages and Disadvantages of Threshold-Based Rebalancing

• Advantages:

- Ensures that your portfolio stays aligned with your investment strategy - Rebalancing is done based on specific data, reducing psychological stress for the investor

• Disadvantages:

- Can lead to more frequent transactions, increasing fees - When markets move sharply, rebalancing can result in losses

Time-Based Rebalancing (e.g., Quarterly)

The second approach is time-based rebalancing. This approach involves regularly reviewing your portfolio at a set time period, typically quarterly or annually. Regardless of market fluctuations, rebalancing will occur even if the weights remain within the original set limits.

Advantages and Disadvantages of Time-Based Rebalancing

• Advantages:

- A planned approach that reduces the need to monitor the market - Suitable for investors with a lower risk tolerance and for those who prefer systematic approaches

• Disadvantages:

- May overlook situations where threshold-based rebalancing could yield better results - You might rebalance unnecessarily, especially if conditions don’t warrant it

Integrating Tax-Loss Harvesting

Another important aspect of portfolio rebalancing is integrating tax-loss harvesting. This strategy is utilized to reduce taxes on capital gains. The process involves selling losing investments within the portfolio to offset profitable investments.

How Does It Work?

1. Identify losing investments you want to sell.
2. Consider purchasing a similar investment to avoid the wash-sale rule.
3. Use the loss to offset taxable gains and reduce overall tax burden.
