MNOV opened up 13%, ran to $3.90, then gave back some of the run by the close.
What happened
Before the open

The open

The close

- In our recaps, this is the only day MNOV 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).
