New Highs Fade. Discipline Compounds
Some of the names on this list will keep setting highs for years, and some are at the top of their run right now. Sorting one from the other, name by name, every day, is the work most investors never keep up with.
That sorting is what the Trefis High Quality (HQ) Portfolio does systematically: about 30 quality businesses screened for the fundamentals that sustain a run, held with rules instead of excitement. It has a track record of outpacing a benchmark that combines the S&P 500, the S&P MidCap 400, and the Russell 2000. Use the high list for ideas; use the portfolio for the compounding.
