Common questions about PEN’s checks
How many technical checks does PEN pass right now?
As of the Aug 27, 2026 close, PEN passes 4 of 10 fixed technical checks — the checks not passing: holding above short-term average, not overextended, outperforming the market, stop distance within range, adequate stop room, quiet pullback volume.
Why does PEN fail the "outperforming the market" check?
PEN has trailed the S&P 500 by 3.6 percentage points over the last 20 sessions, so the relative-strength check fails. It passes once PEN leads the index again.
What price would change PEN's check count?
The nearest flip level is "adequate stop room" passes on a close above $323.13. Each price-anchored check has an exact next-close level, shown in the Flip levels panel above.
