What is one potential downside of frequent rebalancing?

One significant downside of frequent rebalancing is the potential for increased transaction costs and taxes. When investors frequently adjust their portfolio allocations to maintain a desired asset mix, they often incur brokerage fees for buying and selling securities. These transaction costs can add up, particularly for actively managed portfolios.

In addition to transaction costs, frequent rebalancing can trigger capital gains taxes if the rebalancing involves selling assets that have appreciated in value. This incurs a tax liability for the investor, which can diminish overall investment returns. Therefore, while maintaining an optimal asset allocation is essential for risk management and alignment with investment goals, the financial implications of rebalancing too often can negate some of the benefits it offers.

The other options discuss aspects of portfolio management but do not accurately capture the downside of frequent rebalancing. For example, improving portfolio performance and simplifying investment strategy suggest benefits rather than drawbacks, while reducing the need for investment knowledge implies a lack of engagement that could lead to mismanagement. Understanding the cost implications is crucial for making informed investment decisions.
