Impact of Transaction Costs on Portfolio Rebalancing Decisions

A high net-worth individual has engaged your services as a portfolio manager to optimize their investment strategy. The individual holds a diversified portfolio comprising equities, fixed income, real estate, and alternative assets. The client has expressed an interest in rebalancing the portfolio due to significant appreciation in equity holdings, which now disproportionately reflect the client’s risk appetite. However, the client is concerned about the potential transaction costs associated with rebalancing.

As their portfolio manager, your task is to evaluate the implications of transaction costs in the rebalancing process. Analyze how transaction costs can impact the trading decisions for the client’s portfolio, considering both direct costs such as commissions and indirect costs like market impact and tax consequences. In your response, consider strategies that can minimize these transaction costs while ensuring the portfolio still aligns with the client’s investment objectives.

Provide a detailed framework that outlines the steps you would take to approach the rebalancing issue while accounting for transaction costs, and discuss the trade-offs involved in various rebalancing strategies.
