PIRS catching some short covering perhaps near end of the day, sending it up near the critical 5 area. Low 4s held very well after a month long run and consolidation. Expecting this to breakout over 5 barring any extraordinary news; not following company details but certainly ripe for a catalyst. Wouldn't be surprised with upgrade ratings or purchase disclosures in the coming weeks that may drive it further in the near-term.
Biotech seasonality is upon us, further adding to my long bias here.
