Bullish Pennant · playing out now

DXCM just broke higher out of a bullish pennant — a brief, tidy pause inside a strong run. That's usually a breather before another push up.

On this chart, setups like it have followed through about 56% of the time.

As long as price stays above $69.79, the setup is intact — a daily close back below there is the cue to step away.

A natural first target sits near $91.12 — but moves like this often run further. The simple way to follow the rest is to stay with the 10-day average, and only step aside when a day closes below it.

DXCM Support and Resistance Levels

Price found a floor near $67.72 about 5 weeks ago and has been climbing since. On the weekly chart, the next ceiling overhead sits near $275.62 — still about 217% away.

  • Traders commonly watch $275.62 as a target (its 200% 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 $67.72 floor about 5 weeks 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 $79.20. These are chart/swing-derived levels, not formula pivots.
