What happened
Before the open

The open
It opened up 20%, at $2.37. It ran to $2.77 by 10:15 a.m.
The close
It closed at $2.51, 9% 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.

- In our recaps, this is the only day LUNG met the small-cap rule.
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).
