The day before

On September 14, SUGP traded between $0.62 and $0.73 on 320,870 shares.

Pre-market: the float traded by 8:02 a.m.

From 4:00 to 8:00 a.m., fewer than 10,000 shares traded in total, mostly between $0.70 and $0.72. Then the news came.

At 8:00 a.m. PRNewsWire ran: “SU Group Holdings Limited Announces Proposed Acquisition of KM Safety Solution Company Limited”. At 8:01 it ran a second headline: “SU Group Secures Exclusive Distribution Rights for Portable X-Ray System in Hong Kong and Macau”.

From $0.76 at 8:00 a.m. it ran to $0.96 at 8:03 a.m., up 27%. By 8:02 a.m., more shares had traded than exist in the whole float (1.05 million). The 8:02 minute alone was 987,871 shares.

At 8:05 and again at 8:06 the company filed a 6-K (a foreign company's current report). The stock was choppy through both minutes. The 8:05 candle ran from $0.98 down to $0.85.

At 8:10 it traded through $1.00 for the first time. From $0.88 at 8:06 it ran to the pre-market high, $1.19 at 8:11 a.m., on 1.4 million shares in that one minute. By 8:16 a.m. the volume was ten times the float.

It didn't hold. A sell order swept $1.01 down to $0.9993 across six levels at 8:21:16 (87,741 shares), and by 8:22 the low was $0.93. From $0.95 at 8:24 it climbed again to $1.17 at 8:30 a.m., up 23%. At 8:30:39 a buy order for 115,262 shares went through five levels, from $1.10 to $1.14.

At 8:50 a bid wall at $1.03 gave way. It had been on the book since 8:43 and peaked at 135,221 shares. In 5.7 seconds, 107,032 shares traded at exactly $1.03. The 8:50 candle dipped to $0.9953 and closed at $1.03. By the bell, 31.54 million shares had traded.

The open and the walls above it

SUGP opened at $1.05, up 48% from the $0.71 previous close. The opening print was 91,249 shares at $1.05.

This is the part a chart doesn't show you. Stock was stacked on the ask above the price. An ask wall at $1.20 had been on the book since 8:05. The pre-market high, $1.19, was a cent under it. A second ask wall at $1.15 appeared at 8:49. By 9:39 the $1.20 wall had grown to 165,122 shares, about 16% of the float. The $1.15 wall peaked at 140,491 shares at 9:43.

There was a bid wall too, at $1.00. It peaked at 137,733 shares at 9:30 and broke at 9:32:51. In 2.8 seconds, 83,478 shares traded at exactly $1.00. The 9:32 candle hit $0.97, and by 9:35 it was back to $1.15.

From $1.04 at 9:42 it pushed up toward the walls.

Stop It's 9:44. SUGP is at $1.13. Just above, a large ask wall sits at $1.15 (it peaked near 140,000 shares a minute ago), and another sits at $1.20. Would you buy here?

The top at $1.22

Here's what happened. At 9:44:35 the first trade printed at $1.15. In 1.4 seconds, 115,182 shares traded at exactly $1.15 and that wall was gone. A 147,505-share buy order went through four levels, from $1.15 to $1.18.

The $1.20 wall took longer. From 9:44:37 to 9:44:52, 128,947 shares traded at exactly $1.20 (15.2 seconds), and the wall was gone at 9:44:53. The stock hit $1.22, the high so far, in the 9:44 minute, on 1.07 million shares. That is up 71% from the previous close.

The reversal was quick. A sell order at 9:45:05 hit 94,808 shares from $1.20 to $1.18. Another at 9:45:40 hit 74,483 shares from $1.15 to $1.13. The 9:45 candle ran from $1.22 down to $1.13. After the 9:46 minute, it didn't trade above $1.18 again.

The bid at $1.00

The stock drifted down from the top, to $1.03 at 9:53, and back to $1.09 at 10:00. Another bid wall built at exactly $1.00. It first showed at 9:34 and peaked at 151,738 shares at 10:02, about 14% of the float.

Stop It's 10:03. SUGP is at $1.03, down from $1.22 at 9:44. A bid for about 150,000 shares has been sitting at $1.00 since 9:34. Would you buy here?

Press play: the real Level 2, time and sales and chart stop at 10:03 a.m. ET for your call, then show what happened. The clip starts at 10:00 a.m. ET.

At 10:03:47 the first trade printed at $1.00. In 8.2 seconds, 138,914 shares traded at exactly $1.00 and the wall was gone. Sellers hit it. A new ask wall appeared at $1.20 at 10:03:59 and peaked at 189,614 shares (18% of the float) at 10:07.

For a few minutes it held near the old level, between $0.99 and $1.07. Then, at 10:11, a sell order swept 94,640 shares from $0.96 to $0.93 across 60 price levels. At 10:12:20 another took 79,513 shares from $0.92 to $0.90 across 32 levels. It hit $0.89 at 10:12 a.m., down 27% from $1.22. The 10:11 minute alone was 965,916 shares.

The rest of the day

It tried once more. At 10:16 a.m. it pushed to $0.97, a lower high, well under the $1.22 top. At 10:24 it dropped to $0.85, and it kept sliding.

At 11:58 a.m. Benzinga ran: “SU Group Shares Jump After X-Ray Rights, KM Acquisition Plan”. By then SUGP was trading near $0.78.

It had already dipped to $0.72 at 11:35 a.m. In the afternoon it faded: $0.68 at 1:53 p.m., a regular-session low of $0.64 at 3:23 p.m., and $0.64 at the close, below the $0.71 previous close.

By the close, 30.07 million shares had traded in the regular session, plus 31.54 million before the bell. After hours added 1.02 million. For the whole day, 62.63 million shares traded: the float changed hands about 59 times, at about 27 times its normal volume.
