What happened

Draft for review. Not published.

A slow start

The news came the day before: a 9:00 a.m. release on September 14 about three peer-reviewed studies. BNGO opened at $1.31 on the 15th. It reached $1.39 by 9:32. Then it crept toward $1.55 on thin volume.

Stop It's 10:19. BNGO is at $1.56. It has crept up from $1.31 at the open and is trading around $1.55 on thin volume. Would you buy here?

Press play: the real Level 2, tape and chart run from 10:16 a.m. and stop at 10:19 a.m. ET for your call.

That minute it broke. A 37K-share buy swept from $1.56 to $1.58, and the minute hit $1.62. By 10:31 it touched $2.00.

Top at $2.23

The first push did not hold. It slid to $1.82 by 10:36. The second push went higher. It topped at $2.23 in the 10:41 minute.

It did not stay. By 10:49 it had fallen to $1.58, 29% off the high.

The wall at $1.90

The bounce had a ceiling in the book. An ask wall at $1.90 was first seen at 11:02:28. The stock climbed back into the $1.70s and $1.80s below it.

Stop It's 11:30. BNGO is at $1.82. An ask wall sits at $1.90, just above. The high so far was $2.23. Would you buy here?

Press play: the real Level 2, tape and chart run from 11:27 a.m. and stop at 11:30 a.m. ET for your call.

It pushed to $1.88 that minute, a lower high. The wall peaked at 82K shares at 11:30:14 and held. It faded the rest of the day and closed at $1.55, 30% below the high.

What to take from it: The second push stalled under a $1.90 wall, well below the $2.23 top.

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