  • Volume, from the one-minute bars: 32.44 million shares before the 9:30 a.m. open (65%), 8.52 million in the first 30 minutes (17%), and 9.29 million in the rest of the day to 8 p.m. (18%).

  • In our recaps, this is the only day RDHL 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).
