What happened
Draft for review. Not published.
Lawsuit alerts, then a spike
The only news was law-firm alerts about a class action. None of it was business news. The prior close was $2.74.
The 4:00 a.m. minute spiked to $4.24, the day's high, on just 9K shares. A minute later it was back to $2.58.
The 9:45 surge and halt
After a quiet open at $2.88, the buying came all at once. About 302K shares traded from 9:45 to 9:47, and it reached $3.95, still below the pre-market high. The 9:48 minute fell back to $2.89. A volatility pause stopped it at 9:48:30.
Stop It's 9:53. BYAH was halted at 9:48 with the last trade at $2.89, after a run to $3.95 at 9:46. The reopen is seconds away. Would you buy the reopen?
Press play: the real Level 2, tape and chart run from 9:50 a.m. and stop at 9:53 a.m. ET for your call.
The reopen and the slide
It reopened lower, at $2.84 at 9:53:30, with a 13K-share trade at that price. It then fell for four minutes to $2.04, the low of the day.
A late-morning bounce stopped at $2.74. The 3:59 p.m. minute closed at $2.28, 46% under the high. About 721K shares traded in the session, roughly a quarter of the float.
What to take from it: On this day the second push peaked lower than the first, and the halt led to a slide, not a bounce.
