What happened
Draft for review. Not published.
The news came after the close
A $320M all-cash buyout headline hit at 4:15 p.m. on the 27th, when ULBI had closed at $6.36. The first trade on the 28th was $15.45. The 4 a.m. bar already sat 143% above the close.
Then it barely moved. The pre-market high was $15.62 at 8:56 a.m., and 268K shares traded pre-market.
A narrow range at the open
It opened at $15.60, with a 57K-share print in the first second. By 9:35 it touched $15.67, the high of the day, and the low after the open was $15.60.
A bid under a flat tape
The price held near the deal level. An unusually large bid at $15.61 appeared at 2:39 p.m. and grew to 60K shares at 3:06.
Stop It's 3:55. ULBI is at $15.65, with a 60K-share bid at $15.61 below it. It has traded between $15.59 and $15.67 since 9:30. Would you buy here?
Press play: the real Level 2, tape and chart run from 3:52 p.m. and stop at 3:55 p.m. ET for your call.
The bid was pulled at 3:56:44, and the stock closed at $15.61.
What to take from it: With a buyout price set, ULBI traded in a narrow range after the open, so the gap was the main move.
