Draft for review. Not published.
A wall at $0.9898 gets eaten
Before the open, sellers stacked stock at exactly $0.9898 several times. The last wall, 22K shares, appeared at 8:28.
Stop It's 8:42. STAK last traded at $0.9898, with a 22K-share ask wall sitting at that price since 8:28. The previous close was $1.01. Would you buy here?
Press play: the real Level 2, tape and chart run from 8:39 a.m. and stop at 8:42 a.m. ET for your call.
At 8:42:25 a single print of 22,135 shares hit $0.9898 and the wall was gone.
A spike at the open, then nothing
It opened at $1.02 and touched $1.05 in the 9:30 minute. The next minute it traded at $1.01. Most of the day sat between $0.99 and $1.01 on thin volume. It closed at $0.99, with 33K shares in the regular session.
The headline after the bell
A 20-F came at 4:06 p.m. At 4:20 PRNewsWire ran “STAK Inc. Announces Financial Results for Fiscal Year 2026.” In the 4:22 minute it reached $1.28 on 153K shares.
It reached $1.83 at 5:25 p.m., then held near $1.60 into the evening. After hours, 11.8M shares traded, against 33K in the regular session.
What to take from it: STAK did almost nothing in the regular session, then the after-hours volume dwarfed the whole day.
