16.7.2 Attributing Performance

Introduction

In the realm of portfolio management, performance attribution analysis plays a cardinal role in dissecting the various drivers of a portfolio’s performance. By understanding the minutiae of what contributes positively or negatively, portfolio managers are better equipped to refine their strategies and enhance decision-making processes.

Performance Attribution Analysis

Performance attribution analysis functions as a diagnostic tool that breaks down the total return of a portfolio into different contributing factors. This comprehensive examination allows managers and investors to understand the origins of returns as well as deviations from a benchmark or portfolio objectives. Two primary components often scrutinized are asset allocation and security selection.

Asset Allocation

Asset allocation refers to the strategic distribution of investments across various asset classes, such as stocks, bonds, and cash. It is often touted as one of the most critical determinants of portfolio performance. Performance attribution analysis assesses how the allocation decisions of the investor or manager compare against a benchmark. More specifically, it evaluates whether:

• The particular mix of asset classes yielded higher or lower returns than anticipated.
• The decision to overweight or underweight certain assets impacted portfolio outcomes.

Example Diagram: Asset Allocation Attribution

	    title Asset Allocation Attribution
	    "Equities": 50
	    "Bonds": 30
	    "Cash": 10
	    "Alternatives": 10

Security Selection

Security selection involves choosing individual securities within each asset class to achieve desired investment outcomes. This component of attribution analysis is critical for understanding if the chosen securities outperformed or underperformed the sector or overall market indices. When evaluated accurately, this analysis can reveal:

• The impact of selecting specific stocks or bonds within an asset class.
• How well the specific selections performed relative to the average sector performance.

Example Diagram: Security Selection Attribution

	    title Security Selection Attribution
	    "Top Performing Stocks": 45
	    "Middle Performers": 35
	    "Underperformers": 20

Learning and Improvement

The merits of conducting thorough performance attribution extend beyond mere numeric insight. They serve as a learning curve catalyst for investment strategies and future portfolio management decisions, promoting continuous improvement and adaptive market strategies.

• Feedback Loop: By understanding past successes and mistakes, asset managers create a feedback loop that improves decision-making accuracy.
• Strategic Reassessment: Tailoring future investment strategies based on attribution findings can fine-tune asset allocation and enhance security selection.
• Risk Management: Identifying areas of rollback or vulnerability allows for preemptive change, stabilizing returns more consistently.
