AI Summary

Stalk
Sell NowMedium

PTCT remains in a Stage 3 distribution phase with consistent lower highs and lower lows, trading below declining EMAs and SMAs. The medium-term bias is bearish, favoring sell-side engagement on rallies into the 9/20 EMA and 50 SMA zones. Short-term price rejection at these EMAs confirms Sell Now execution. A decisive break below the recent support cluster around $71.70 would open further downside, while reclaiming and holding above the dynamic resistance would negate the bearish outlook.

  • We will expect there to be revenue in Q3 from Suffiance as we have already begun delivering commercial product in Germany, and we've gotten patient start forms in US and expect to be able to ship Suffiance to patients in the next couple of weeks.
