On the day's lists: the intraday runners, after-hours movers. It is here because it met the small-cap rule on the intraday runners: price $2 to $20, up 10% or more, relative volume 5× or more, float under 20 million shares, its high reached $1 or more and it started the day at $20 or under (the rule every page uses).
