What happened
Before the open
The news came first: news at 8:00 a.m. Before the bell it reached $11.44, on 1.6M shares.
The open
It opened up 22%, at $10.90. It ran to $12.30 by 9:41 a.m.
The close
It closed at $10.62, 14% under its high.
What to take from it: The high came early. Most of the run was gone by the close, so the move was in the morning, not the hold.

On the day's lists: the intraday runners. It is here because it was in play on the intraday runners: up 30% or more on $3 million or more really traded, outside the small-cap rule's price, relative volume or float, its high reached $1 or more and it started the day at $20 or under (the rule every page uses).
