MRK Support and Resistance Levels

Price is being turned away at a ceiling near $131.10 and starting to slide. On the weekly chart, the next floor below sits near $114.79 — about 10% away.

  • Traders commonly watch $114.79 as a target (its 38.2% retracement) — think of it as a sensible next stop, not a guarantee.
  • That floor is the first place the slide might steady — worth watching how price behaves as it gets there.
  • There's nothing to act on yet — the spot to watch is right at the $131.10 ceiling, where price is testing it now, not out here in the slide. Chasing once price pulls away tends to be worse odds.

Nearest auto-detected support sits near $125.42. These are chart/swing-derived levels, not formula pivots.
