What happened
Draft for review. Not published.
A gap, then a slide
YMAT opened at $2.55, about double the $1.28 close. A 50K-share bid at $2.07 was pulled at 9:33:12. By 9:55 it had slid to $1.95.
The wall at $3.03
The first halt reopened higher. Then a big ask wall sat at $3.03 from 10:41.
Stop It's 10:44. YMAT is at $2.97. Since 10:41, a large block of shares has been offered at exactly $3.03, just above. Would you buy here?
Press play: the real Level 2, tape and chart run from 10:41 a.m. and stop at 10:44 a.m. ET for your call.
Buyers ate the wall. About 45K shares traded at $3.03 in 4.8 seconds.
At 10:45:10 it was halted at $3.57 with a 156K-share bid underneath.
The 10:45 halt
Stop It's 10:50. YMAT was halted at $3.57 and is reopening at $3.66. A bid wall of about 156,000 shares sat at $3.57 before the halt. Would you buy the reopen?
Press play: the real Level 2, tape and chart run from 10:47 a.m. and stop at 10:50 a.m. ET for your call.
It reopened at 10:50:10 at $3.66 and hit $4.49, the high, that minute. The $3.57 bid was pulled at 10:58:40. It faded and closed at $2.84.
What to take from it: On YMAT no wall held: the $3.03 wall was eaten and the $3.57 bid vanished.
