A portfolio manager is evaluating the performance of an equity portfolio that consists of stocks across various sectors. The portfolio's return for the year was 15%, compared to a benchmark return of 10%. The manager seeks to understand the causes of the portfolio’s excess return over the benchmark by employing performance attribution. The manager notes that the consumer discretionary sector, in which the portfolio was overweighted, experienced a return of 20%, while the energy sector, in which the portfolio was underweighted, had a return of 5%.
Given this information, which of the following statements best explains the performance attribution of the excess return of the portfolio compared to the benchmark?
