What happened

A quiet morning, then a spike

News came out the day before (8:30 a.m. on October 19), and YMAT sat near $1.80 for hours. At 9:05 the volume picked up. The float is 2.7M shares.

Ask walls in the way

Sellers stacked offers above the price, each 1.2% to 1.9% of the float, at $2.30, $2.50, $2.53 and $2.60.

Stop It's 9:12. YMAT is at $2.20. It was $1.79 at 8:59, and a large offer (up to 45K shares) sits at $2.30. Would you buy here?

Press play: the real Level 2, tape and chart run from 9:09 a.m. and stop at 9:12 a.m. ET for your call.

The $2.30 wall was eaten at 9:12:16. At 9:13 the stock reached $2.81 on 747K shares in that one minute. A 51K-share offer at $2.50 was eaten at 9:13:07, and the $2.60 offer was pulled at 9:13:12.

The top, then the slide

After $2.81 it was back at $2.34 by the end of that minute. It pushed again to $2.69 at 9:15, a lower high. A 33K-share bid at $1.87 held until 9:22, then 49K shares traded there in nine seconds and it was gone.

Stop It's 9:30. YMAT opens at $1.80. It was $2.81 at 9:13 and the previous close was $1.83. Would you buy here?

Press play: the real Level 2, tape and chart run from 9:27 a.m. and stop at 9:30 a.m. ET for your call.

It slid to $1.65 at 9:39, drifted near $1.90 through the morning, and closed at $2.01, 28% under the high.

What to take from it: YMAT's spike was over in minutes: ask walls broke on the way up, but the bid at $1.87 broke on the way down.
