What happened
Draft for review. Not published.
A pre-dawn spike
BDRX made its big move hours before any news. From a $1.12 close it hit $3.40 at 5:21 a.m., the day's high.
The headline
The 8:00 warrant deal hit an already fading stock. It fell from $1.98 to $1.09 by 9:05.
Two walls at the open
A big seller capped it here. From 9:17, about 103K shares sat offered at $1.25.
Stop It's 9:25. BDRX is at $1.23. A wall of about 100,000 shares has been offered at $1.25 since 9:17. Would you buy here?
Press play: the real Level 2, tape and chart run from 9:22 a.m. and stop at 9:25 a.m. ET for your call.
At 9:26:06 one buy order swept 103K shares up to $1.29. The wall was eaten, not pulled. A 107K-share bid then appeared at $1.26.
Stop It's 9:30. BDRX opens at $1.28. A bid of over 100,000 shares sits at $1.26, two cents below. Would you buy here?
Press play: the real Level 2, tape and chart run from 9:27 a.m. and stop at 9:30 a.m. ET for your call.
Sellers hit it at 9:30:37. In under 4 seconds, 89K shares traded at $1.26 and the bid was gone.
Fade to the close
A 10:51 push reached $1.43 and faded. It closed at $1.33, 61% under the high.
What to take from it: On BDRX the big move and the high came before the bell, and the regular session never got close.
