Morningstar is an independent provider of investment research and provide information on approximately 380 000 investment offerings about mutual funds. Morningstar are most known for their “star” rating system, which rates funds from the lowest 1-star to the highest 5-stars.

Since investors frequently use fund data provided by Morningstar, we will evaluate whether investing in funds with higher fees and higher ratings would end up with higher returns. Examinations will be made if there is a relationship between mutual fund performance and the management fees within top-rated (5-star) funds and bottom-rated (1-&2-star).

The mutual funds which are included in this thesis are United Kingdom (UK) managed and invested in three different markets; Asia-Pacific except-Japan, Europe except UK-Large Cap, and the United States (US) Market. This allows us to compare different markets at different stages of maturity.

The results clearly show that the top-rated funds within all three markets outperformed the bottom-rated funds. Furthermore, the results demonstrate that the investor in general will earn a higher return by paying a higher management fee (TER) for the top-rated funds in all regions. The results also show that the TER for the bottom-rated funds in Europe and US market is higher compared to the top-rated funds. This means that the investor will pay higher fees for funds that do not perform well.
