• From news to the move: the first trade 20% above the previous close came 2 hours 9 minutes after the latest news item before it (Seeking Alpha, 6:58 a.m.).

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

The exchange's halt feed shows no halts for QMCO that day.
