((Portfolio sector beginning weight plus purchases) – (Benchmark sector beginning weight))Īllocation effect: 0.0015=(0.1-0.05)*0.03 Interaction Effect The positive allocation effect occurs when the overweight positions in a segment outperform the same segment within the benchmark, where the negative allocation effect occurs when overweight segment positions in the portfolio underperform the same segment in the benchmark. The allocation effect is calculated as the arithmetic difference between the portfolio’s sector (or region) weights and returns against those in the target index. It determines whether taking active positions in a particular segment against the benchmark, either overweight or underweight, was a contributor (positive) or a detractor (negative) to the overall portfolio performance. The allocation effect measures the manager’s ability to generate an above-market return by allocating funds to specific sectors, regions, or asset classes. ((Portfolio sector beginning weight plus purchases) – (Benchmark sector beginning weight))*((Portfolio sector return) – (Benchmark sector return)) ((Benchmark sector beginning weight))*((Portfolio sector return) – (Benchmark sector return)) On the other hand, if the securities held in the portfolio underperformed the same (or similar) securities in the benchmark, the selection effect will be negative and will signal poor investment decisions. Positive stock selection occurs when the manager has made good investment decisions and picked securities that outperformed the same (or similar) securities in the benchmark. Whether a fund manager has a positive or negative view on a specific security, he or she will normally go overweight or respectively underweight in that security compared to the benchmark index. The selection effect measures the manager’s ability to pick specific stocks (or other securities) relative to a benchmark – it could be either positive, negative, or in rare cases neutral if equals zero.

Performance attribution could increase transparency and reassure investors that the strategy is properly implemented.
