Lesson Objective: To understand the process of periodic portfolio review, including the selection of appropriate benchmarks and the management of portfolio rebalancing.

In-Depth Notes:

1. The Importance of Monitoring:
Portfolio monitoring is the ongoing process of tracking the portfolio’s performance, risk, and alignment with the client’s objectives. Monitoring is essential for ensuring that the portfolio remains on track to meet the client’s goals and for identifying any issues that may require action.

2. Performance Measurement:

• Time-Weighted Rate of Return (TWR): Measures the compound growth rate of the portfolio, eliminating the impact of external cash flows.

• Money-Weighted Rate of Return (MWR): The internal rate of return (IRR) of the portfolio, which accounts for the size and timing of external cash flows.

• Benchmarking: Performance is typically measured against a benchmark, such as a market index (e.g., S&P 500) or a custom benchmark that reflects the portfolio’s investment policy.

• Risk-Adjusted Performance Metrics:

  • Sharpe Ratio: Measures the excess return per unit of total risk (standard deviation).

  • Treynor Ratio: Measures the excess return per unit of systematic risk (beta).

  • Jensen’s Alpha: Measures the excess return of a portfolio relative to its expected return, based on the CAPM.

3. Performance Attribution:
Performance attribution is the process of identifying the sources of portfolio returns.

• Asset Allocation Effect: The impact of the strategic allocation to different asset classes on portfolio returns.

• Security Selection Effect: The impact of selecting individual securities within an asset class.

• Interaction Effect: The combined effect of asset allocation and security selection.

4. Portfolio Rebalancing:
Rebalancing is the process of adjusting the portfolio’s holdings to return to the target asset allocation. Over time, market movements will cause the portfolio’s weightings to drift away from the target. Rebalancing is essential for maintaining the portfolio’s intended risk profile.

• Rebalancing Triggers:

  • Periodic Rebalancing: Rebalancing at fixed intervals (e.g., monthly, quarterly, annually).

  • Threshold Rebalancing: Rebalancing when an asset class deviates from its target allocation by a specified percentage (e.g., 5%, 10%).

• Rebalancing Methods:

  • Buy/Sell: Selling overweighted assets and buying underweighted assets.

  • Cash Flow: Using new contributions or withdrawals to rebalance the portfolio.

• Tax Considerations: Rebalancing can trigger capital gains taxes. Tax-efficient rebalancing may involve using new contributions to purchase underweighted assets or harvesting tax losses.

5. Reporting to Clients:
Regular reporting to clients is a critical part of the portfolio management process. Reports should include:

• Portfolio Performance: Returns for the period and cumulative returns.

• Risk Metrics: Standard deviation, beta, and other relevant risk measures.

• Portfolio Composition: The current asset allocation and holdings.

• Benchmark Comparison: How the portfolio performed relative to its benchmark.

• Market Commentary: A summary of market conditions and the rationale for investment decisions
