Why Gold

The highest bar Morningstar sets

Morningstar's Medalist Rating looks forward: whether a fund is likely to outperform its peers over a full market cycle, after fees. Gold sits at the top of that five-tier scale, and it is the only rating we include.

Morningstar Medalist Rating

  1. Gold

    Highest conviction. The only rating we use.

  2. Silver

  3. Bronze

  4. Neutral

  5. Negative

People

The managers and analysts running the strategy: skill, experience, and a team that can keep delivering.

Process

A clear, repeatable way of investing, not a one-off bet.

Parent

The firm behind the fund: whether it puts investors first.

Expected outperformance is judged after costs. High fees can pull a fund down the scale even if the team is strong.

This is Morningstar's rating, not Mestral's. Morningstar Medalist Rating
