• From news to the move: the first trade 20% above the previous close came 8 hours 24 minutes after the latest news item before it (Seeking Alpha, Sep 2, 7:44 p.m.).
• Volume, from the one-minute bars: 395,659 shares before the 9:30 a.m. open (3%), 2.63 million in the first 30 minutes (19%), and 11.17 million in the rest of the day to 8 p.m. (79%).
• In our recaps, this is the only day CHPT 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 CHPT that day.
