The day before
On August 17, XOS opened at $2.09 and reached $4.77. It closed at $2.09.
The news came after the close. At 4:30 p.m. GlobeNewsWire ran: “Xos Secures U.S. Air Force Contract to Deliver Deployable Mobile Charging, Marking Defense Market Entry”. The last after-hours trade that evening was $3.91.
Pre-market: the float traded by 6:05 a.m.
The first trades on the 18th were at $3.73, already well above the $2.09 close. The low so far, $3.33, came at 4:07 a.m.
From $3.43 at 4:24 a.m. it ran to $4.36 at 5:57 a.m., up 27%. By 6:05 a.m., more shares had traded than exist in the whole float (8.60 million).
From $4.09 at 6:20 a.m. it ran to $5.04 at 6:52 a.m., up 23%. At 7:00 it touched $5.02 and fell back as low as $4.50 at 7:03.
Stop It's 7:15 a.m. XOS is at $5.14. It was $4.64 at 7:10 and has traded above $5 since 7:12. The pre-market high so far is $5.25. Would you buy here?

The high so far came in that minute: $5.38 at 7:15 a.m., before the bell. Within two minutes it was back at $4.89.
It then drifted down. A bid wall had built at $4.50 (peak 59,914 shares at 7:40). At 8:22 sellers ate it: 44,409 shares traded at exactly $4.50 in about five seconds. The pre-market low after the high was $4.35 at 8:24 a.m., down 19% from $5.38.
At 8:54 a.m. Benzinga ran: “Xos Stock Surges on US Air Force Contract Win”. By the bell, 29.19 million shares had traded pre-market, about 3.4 times the float.
The open and the slide to $4.01
It opened at $4.52, up 116% from the previous close and 16% under the pre-market high. The first minute traded 904,788 shares and ranged from $4.35 to $4.68. A 164,208-share print went through at $4.55 right at 9:30:00.
At 9:31:20 one sell order swept 116,176 shares from $4.47 down to $4.38 across ten price levels.
By 10:24 it had slipped to $4.01. From there it crept up.
Late morning
From 10:47 the stock climbed out of a quiet stretch around $4.19 to $4.40 by 10:48.
Stop It's 10:58. XOS is at $4.57. It was $4.40 a minute ago on 227,181 shares, the most volume in a minute since 10:48. The high so far is $5.38. Would you buy here?
Press play: the real Level 2, time and sales and chart stop at 10:58 a.m. ET for your call, then show what happened. The clip starts at 10:55 a.m. ET.
At 10:58:04 a single buy order swept 307,026 shares from $4.63 to $4.91 across 29 price levels. The minute reached $4.95, a lower high under the $5.38 top, on 857,163 shares. Then it faded: $4.35 at 11:00 and $4.12 at 11:06.
Through midday it traded mostly between $4.15 and $4.50. At 1:07 p.m. Invezz ran: “XOS stock soars on Air Force contract: should you chase the rally?”. By then the stock was at $4.18.
The wall at $4.50
This is the part a chart doesn't show you.
From 1:14 p.m. on, an ask wall sat at exactly $4.50. A Form 144 was filed at 3:19 p.m. The wall peaked at 93,669 shares at 3:34 p.m., 1.1% of the float. The stock sat just under it, at $4.45 by 3:34 and $4.48 by 3:35.
Stop It's 3:36. XOS is at $4.48. An ask wall at $4.50 peaked at 93,669 shares at 3:34, and the stock is two cents under it. Would you buy here?
Press play: the real Level 2, time and sales and chart stop at 3:36 p.m. ET for your call, then show what happened. The clip starts at 3:33 p.m. ET.
From 3:36:04, trades printed at exactly $4.50. In 4.6 seconds, 81,997 shares traded at exactly $4.50 and the wall was gone. It wasn't pulled. Buyers ate it. The 3:36 candle reached $4.56 on 237,004 shares.
The close and after hours
It closed at $4.46, 17% under the $5.38 high. That high came before the bell, 19% above where the stock opened.
The regular session traded 17.20 million shares, about twice the float. Add 29.19 million pre-market and 1.98 million after hours and the day's total is 48.37 million, at 52 times normal volume. After hours it touched $4.80 at 6:02 p.m. and was at $4.11 by 8:00.
What to take from it
- After the top, the next push stopped lower. $5.38 at 7:15 a.m., then $4.95 at 10:58 a.m., the minute of a 307,026-share sweep.
- The float traded over before the open. By 6:05 a.m. more shares had traded than the float holds, and the high of the day came before the bell.
- The screen price is not your price. At the high and again at the wall break, 5,000 shares cost $121 more than the screen showed.
