Pre-market: a headline at 7:50

AIFF closed the day before at $0.93. On September 16 it traded between $0.91 and $1.00, on 27,156 shares. That is a very quiet stock.

The first trade on the 17th was one share at $0.90 at 4:30 a.m. By 6:28 a.m. it was at $0.89, the low so far. Only a handful of shares traded before 7:50.

At 7:50 a.m. GlobeNewsWire ran: “Firefly Neuroscience's Evoke™ Platform Selected to Bring Objective Brain-Function Insights to Radial's AI-Native Operating System for Brain Medicine”. In that same minute it hit the pre-market high, $1.12 at 7:50 a.m., and closed the minute at $1.03.

It did not hold. In the 7:51 minute it traded as low as $0.93, back at the previous close. By 8:02 it was $0.93, and the 8:03 low was $0.93. Of the 131,713 shares traded before the bell, 31,260 came in those first two minutes. After that it traded thinly, with long gaps between prints. It was back above $1.00 at 8:49 and sat at $1.02 into the open.

The open and a quiet midday

It opened at $1.02, up 10% from the previous close. It worked up to $1.10 at 9:37. Then it slipped back to $1.03 by 9:56.

From 10:13 to 1:37 p.m. it stayed between $1.03 and $1.09, and many minutes had no trades at all. By 1:37 p.m. it was at $1.07, with no halts so far.

1:38 p.m. and the wall at $1.14

At 1:38 p.m. a buy order for 13,375 shares went through five levels, from $1.08 to $1.12. That minute traded 14,844 shares and closed at $1.12, the most volume in one minute since the 10:03 bar. By 1:40 it was at $1.14. It then chopped between $1.11 and $1.15 for the next 35 minutes.

The next push came at 2:20 p.m. At 2:20:28 a bid wall showed up at $1.14, peaking at 83,149 shares at 2:20:32 (0.6% of the float). It was pulled at 2:21:50. The 2:20 minute ran from $1.14 to $1.17 on 11,979 shares, and the 2:21 minute reached $1.18.

$1.36 and the pullback

What to take from it

• A headline spike can fade in minutes. AIFF hit $1.12 at 7:50 a.m. and was back at the $0.93 previous close by 8:02. The real move came about six and a half hours later.
• After the top, the next push stopped lower. $1.44 at 2:55 p.m., then $1.43 at 3:03 p.m., and the stock fell to $1.26 within minutes.
• The move came with volume. AIFF sat in a narrow range on thin volume for hours. Minute volume first passed 100,000 shares at 2:37 p.m.
