Jennifer Engle, CFA, Chairman of Engle Capital Management wants to implement a defined rebalancing process for all of the portfolios managed by her firm. Engle is aware that calendar rebalancing or percentage-of-portfolio rebalancing are the two primary methods of rebalancing a portfolio. Engle asks Michael Buening, an analyst, to prepare a report on the best rebalancing method for specific criteria. Specifically, Engle wants to know which method would be best under three different criteria: (1) time spent on the rebalancing process, (2) expense of trading, and (3) consistency of portfolio asset allocation. Which of the following correctly lists the best rebalancing method for each of Engle’s criteria? | Time Spent on Process | Expense of Trading | Consistency of Allocation |
A)
| Calendar rebalancing | Percentage-of-portfolio | Calendar rebalancing |
|
| B)
| Calendar rebalancing | Unknown | Percentage-of-portfolio |
|
| C)
| Unknown | Calendar rebalancing | Percentage-of-portfolio |
|

The primary benefit to calendar rebalancing is that it provides the discipline of rebalancing without the constant need to monitor the portfolio. The result is that calendar rebalancing is the less time intensive rebalancing method.
Trading expense related to rebalancing is a result of where asset thresholds are set under the percentage-of-portfolio method, and also the volatility of the portfolio. For a portfolio with low volatility and wide thresholds, calendar rebalancing would result in more frequent trading, while a volatile portfolio with tight thresholds would lead to more frequent trades under the percentage-of-portfolio method. Therefore, the best method if trading expenses were the primary criteria is unknown.
The primary benefit of percentage-of-portfolio rebalancing is that it minimizes the degree to which asset classes can violate their allocation corridors, resulting in the most consistent asset allocation. With calendar rebalancing, the portfolio allocation could vary widely in between rebalancing dates. |
