Questiоn 5C (13.34 pоints) An аsset mаnаger оversees an actively managed international equity portfolio benchmarked against the MSCI World Index. Unlike a domestic equity portfolio, the manager makes three independent investment decisions: Country allocation – deciding how much of the portfolio to invest in each country relative to the benchmark. Security selection – selecting individual stocks within each country. Currency hedging – deciding whether to hedge (reduce or eliminate) the portfolio's exposure to fluctuations in foreign exchange rates. A successful currency hedging decision can either increase or decrease portfolio returns relative to the benchmark. During the past year, the portfolio outperformed the benchmark by 1.35% (135 basis points). A performance attribution analysis produced the following results: Source of Value Added Contribution Country allocation +0.80% Security selection –0.20% Currency hedging +0.95% Interaction effect –0.20% Total excess return +1.35% The asset manager had informed clients that the firm's primary competitive advantage was its ability to identify undervalued stocks within individual countries. Discuss what these attribution results imply about the manager's investment process. In your answer: Explain what each attribution component measures. Evaluate whether the manager generated superior performance using the strategy described to clients. Discuss what the attribution results suggest about the manager's strengths and weaknesses. Explain what additional information you would seek before deciding whether to continue investing with this manager.
