- 1MRK closes the Quality gap — currently 13 points behind, the largest single contributor to ABBV's edge.
- 2MRK's existing bullish trend signals translate into factor-score gains — the rules are already firing, but the scores have not yet followed.
- 3ABBV's conflicting signal state resolves bearish — it currently carries 3 bullish and 1 bearish rules at once.
- 4A regime shift changes factor weighting — the composite weights Quality and Value at 30% each, so a rotation toward either would move the result most.
