The chapters are independent of each other in terms of theoretical grounding and methodology but complement each other by investigating the three different angles related.In Chapter 2 is analysed the Morningstar Star Rating can help the predictive power of future performance, in Chapter 3 the Morningstar Analyst Rating and if analyst opinions can help identifying the best mutual funds and in the Chapter 4 if Morningstar Sustainability Scores and ESG ( enviromental, social and governance) scores can evaluate the effect of portfolio management decisions based on sustainable criteria. Our conclusions, support the a strong ability of the predictive power of Star Ratings and a weak predictive power of Analyst Morningstar Ratings.
