AJG Support and Resistance Levels

Price found a floor near $200.63 about 2 months ago and has been climbing since. On the weekly chart, the next ceiling overhead sits near $316.88 — still about 28% away.

  • Traders commonly watch $316.88 as a target (its 78.6% extension) — think of it as a sensible next stop, not a guarantee.
  • That ceiling is the first place the climb might pause — worth watching how price behaves as it gets there.
  • There's nothing to act on here — the spot to watch was the $200.63 floor about 2 months ago, when price bounced there, but price has already pulled higher. What's left is the climb playing out, not a fresh starting point.

Nearest auto-detected support sits near $196.21, resistance near $258.18. These are chart/swing-derived levels, not formula pivots.
