AHMA on September 10, 2026, one-minute bars in New York time. Shaded: before the 9:30 a.m. open and after the 4:00 p.m. close. Bands: halts.

Pre-market: a spike and a full give-back

The previous close was $1.28. The first pre-market trade was at 4:08 a.m., at $1.23. Then it was quiet. Most minutes had no trades.

At 4:58 a.m. it woke up. In two minutes it ran from $1.35 to $1.78 at 4:59 a.m., the pre-market high. At 5:00 a.m. it fell to $1.18 on 41,567 shares, the busiest pre-market minute. By 5:02 a.m. it touched $1.16, the low so far.

After that it sat between about $1.16 and $1.36 for hours. Many minutes had only a few hundred shares. 132,653 shares traded before the bell. That is small next to what came later.

The open and the halt

At 9:29 a.m. it was at $1.40. It opened at $1.42 and traded to $1.46 in the 9:30 minute.

The 9:31 minute was the breakout. It ran from $1.50 to $1.95 on 114,255 shares, through the $1.78 pre-market high. At 9:32:12 it was halted (a volatility pause). It reopened at 9:37:12 at $2.05.

A single trade of 68,236 shares printed at $2.05 at the reopen. The reopen was above the $1.95 where the stock had stopped.

Stop It's 9:37. AHMA has been halted since 9:32, after its last trade at $1.95, and the pause is about to end. Would you chase it when it reopens at $2.05?

The 9:37 minute printed $2.14, the high so far, and 617,928 shares traded, the most of any minute. It closed that minute at $1.90. Two big sell sweeps hit within seconds of the reopen: 21,858 shares from $2.01 to $1.97, then 23,225 shares from $1.97 to $1.92.

By 9:39 it was at $1.76. Through 10:26 it did not get back to $2.14.

The wall at $1.90

From 9:41 a.m. someone was offering stock at exactly $1.90. It peaked at 41,052 shares at 9:50, about 1% of the float, across all exchanges. Above it, another wall at $1.98 appeared at 9:51 and was pulled at 10:00.

It hit $1.92 at 9:51, briefly above the $1.90 wall, then fell to $1.53 at 9:53. It slid to $1.47 at 10:06, then spent the next 15 minutes between about $1.50 and $1.66.

Stop It's 10:27. AHMA is at $1.79 and has climbed from $1.63 over the last few minutes. An ask wall has been sitting at $1.90 since 9:41. Would you buy here?

Press play: the real Level 2, time and sales and chart stop at 10:27 a.m. ET for your call, then show what happened. The clip starts at 10:24 a.m. ET.

From 10:27:55 to 10:27:56, 19,243 shares traded at exactly $1.90. In about a second the wall was gone, eaten at 10:27:57. It wasn't pulled. Buyers ate it.

A sell sweep of 27,617 shares followed at 10:28:44, from $1.85 down to $1.80. A new $1.90 ask wall showed up later, at 10:55.

A lower high and a slow fade

At 10:31 it pushed to $1.94, under the $2.14 top. It closed that minute at $1.90, then slid. A sweep sold 27,316 shares from $1.65 to $1.61 at 10:41, as a $1.65 bid wall broke.

From 10:42 until about 1:27 p.m. it mostly drifted between $1.54 and $1.69, with a drop to $1.54 at 12:11. After 1:27 p.m. it climbed to $1.86 by 1:35, then held mostly in the $1.65 to $1.85 range. At 3:09 a big sweep took it to $1.64 for a moment, and it recovered to $1.74 the same minute.

It closed at $1.75 in the 4:00 p.m. bar. After hours it ranged from $1.68 to $1.85 on thin volume.

For the regular session, 8.61 million shares traded: about 2 times the 4.19-million-share float. Relative volume was about 701 times normal.
