That has mattered: over the past 2.7 years, funds on this rung beat bottom-rung funds by about 3.8% per quarter, and beat the S&P in 43% of fund-quarters versus their 22%. The evidence argues this fund earns its seat.

The grade scores this fund's specialist share, the slice that overlaps what the top 1% of proven funds are building. We ignore index ballast and names outside our edge on purpose: that slice is small, and it's what decides the outcome.

The read · what to do with it
MTINX earns a C grade, ranking 195 of 500, with specialists backing only 39.6% of assets and 31% sitting in late-stage trades. Bright spots include early positions in ABBV, IRM, and MET, but AVGO, IBM, and GOOG are all Fading, which is a meaningful drag on the thesis.
→ Watch the Fading weight in AVGO, IBM, CVS, and GOOG closely, as specialists exiting those four names total over 4% of the fund.
→ Compare MTINX against the three higher-graded peers in this segment before adding new money, given the C grade and crowded AT&T position.
