Tolerance-Based Rebalancing
A Dynamic Portfolio Management Approach for Risk-Adjusted Returns
The importance of Rebalancing
What is it?
Rebalancing is the way in which portfolio asset allocations are managed over time.
Why is it important?
Ensures portfolio alignment with an investor’s target asset allocation and risk tolerance.
What are the benefits?
Rebalancing can potentially have a material impact on returns.
Portfolios are typically designed to align with an investor’s risk tolerance. However, market volatility can cause a portfolio to drift from its intended asset allocation strategy over time. This drift often occurs when riskier assets outperform others, potentially increasing risk beyond what an investor is comfortable with.
Systematic rebalancing is a key component of portfolio risk management, keeping investments aligned with an investor’s risk-adjusted return.
The most common rebalancing approaches are calendar-based, and tolerance-based rebalancing.
Calendar-Based Rebalancing (CBR)
This approach rebalances portfolios at regular fixed date intervals, typically quarterly or annually,
regardless of how much the portfolio has drifted from its target.
Tolerance-Based Rebalancing (TBR)
TBR offers a more disciplined approach to portfolio management, using threshold-based triggers to rebalance when predefined limits are breached.
For example, rebalancing is activated in the Vantage Earth Portfolio 50 if, equity exposure exceeds a 57.6% upper drift threshold or 41.7% lower drift threshold. As shown in the chart below, over three years, calendar-based rebalancing vs. threshold-based rebalancing is compared. Calendar-based rebalancing occurs annually, while tolerance-based rebalancing only activates when portfolio drift exceeds its tolerance band (e.g., 57.6% equity).
How Calendar VS TBR responds to Market Drift
Please note that tolerance-based rebalancing may occur more frequently than calendar-based rebalancing,
depending on market conditions.

- ebi whitepaper, Tolerance Based Rebalancing: Data or Date.
In our earlier example, a portfolio with a 50% equity target, TBR would rebalance only if equity allocation moves beyond a 57.6% upper or a 41.7% lower threshold. This dynamic strategy ensures efficient portfolio management without excessive trading.
