What happened

News before dawn

A 6:00 a.m. headline woke up a thin stock. Only 1,500 shares traded the day before, and it closed at $1.12.

The headline said Immuron would launch PROIBS® in the United States. Big volume came a few minutes later. By 6:48 a.m., more shares had traded than the whole float. It reached $1.98 before the bell.

The push to $1.99

The open brought one more push. It opened at $1.81, up 62%. At 9:45 a.m. it hit $1.99 on over 1M shares. A large ask wall sat at $2.00.

A bid wall of about 153K shares had formed at $1.84 at 9:41.

Stop It's 9:48. IMRN is at $1.90. Just below, a bid wall that peaked at about 150,000 shares at 9:41 sits at $1.84, and the stock hit $1.99 three minutes ago. Would you buy here?

Press play: the real Level 2, tape and chart run from 9:45 a.m. and stop at 9:48 a.m. ET for your call.

The wall did not hold. It was eaten at 9:49:28, with 25K shares trading at $1.84. A few minutes later the stock was at $1.71.

Lower highs, broken bids

The next push stopped lower, at $1.86 by 10:07. A 190K-share bid at $1.75 was eaten at 10:45:59, and it fell to $1.66 within minutes. A bid at $1.55 broke at 1:23:57 p.m. The low after the open was $1.54. It closed at $1.78, up 59%.

What to take from it: On IMRN, the bid walls at $1.84 and $1.75 both broke, and the push after the $1.99 top stopped lower.

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