Pre-market: almost nothing

The day before, YMAT traded between $1.31 and $1.49 on just 15,186 shares. The official close was $1.32.

Pre-market was thin. The first trade was one share at $1.33 at 4:22 a.m. The pre-market high was $1.37 at 5:00 a.m., also on one share. 1,727 shares traded before the bell. No news headline appears in the data for the day.

The open and a slow morning

It opened at $1.33, a penny above the previous close. At 9:49 it slipped to $1.31 on 3,190 shares, and by 9:53 it was at $1.25. It spent most of the morning between $1.20 and $1.27, with some minutes where nothing traded at all. At 12:11 it was $1.20.

The afternoon move

At 12:41 it was still $1.20. Then it started to move. By 12:43 it was at $1.34, and the 12:44 minute had no trades.

That minute traded 4,932 shares and ran to $1.46. At 12:49 it was halted (a volatility pause) with the last trade at $1.71. The 12:49 minute traded 21,339 shares.

It reopened at 12:59:48 at $1.98, 16% above where it stopped. The first big print was 59,175 shares at $1.98.

$1.99 was the high so far, in the 12:59 minute. That minute traded 141,245 shares. The next candle, at 1:00 p.m., dropped to $1.41 and traded 257,398 shares.

The bounce and the $1.25 bid wall

It did not go straight down. At 1:02 p.m. a single sell order went through four price levels, 16,431 shares from $1.55 to $1.52. Then it bounced. At 1:07 p.m. it pushed to $1.90, a lower high under $1.99. At 1:09 p.m. a sell of 12,439 shares ran from $1.73 down to $1.68. By 1:24 p.m. it was $1.32, and by 1:30 p.m. it was $1.37.

Level 2 shows something a chart doesn't. A bid wall formed at $1.25 at 1:23 p.m. and grew to 21,755 shares at 1:24 p.m., about 0.8% of the float.

Here's what happened. At 1:37:50 the wall was gone. In the seconds before, 9,710 shares traded at exactly $1.25, from 1:37:46 to 1:37:49. The 1:38 candle went to $1.20.

The afternoon and the close

From there it drifted. It was $1.18 at 2:02 p.m. The low after the open was $1.16 at 2:57 p.m., on 10,933 shares. A short pop at 3:22 p.m. took it to $1.26, it slipped back to $1.17 at 3:32 p.m., then moved up into the close. It reached $1.28 at 3:58 p.m., and the 4:00 p.m. minute traded 22,858 shares and ran to $1.36.

By the close, 2.24 million shares had traded, about 83% of the 2.70 million-share float, at about 2.3 times normal volume.

What to take from it

• A halt can reopen higher than it stopped, and the book was thin at the reopen. It stopped at $1.71 and reopened at $1.98. A 5,000-share market buy at that second would have cost $1,052 more than the screen showed.
• A bid wall is not a floor. The $1.25 wall was gone at 1:37:50, and the stock traded down to $1.20 within the next minute.
• After the top, the next push stopped lower. $1.99 at 12:59, then $1.90 at 1:07 p.m. It closed at $1.36, 32% below the high.
