A reader asked: “Why not have Ned Davis Research or Lowry’s Research in your ranking?”
Ned Davis Research and Lowry Research are largely quantitative analysts rather than qualitative commentators, so statistical testing of their specific methods or conclusions is more appropriate than subjective grading of market commentaries (which they apparently do not issue anyway).
Subjective grading is a fallback for commentators who provide vague reasoning, judgmental interpretation (for example, of charts) or “black box” conclusions not amenable to quantitative testing.
