What happened
The 8:15 headline
On this day a $3M private placement headline woke up a quiet stock at 8:15 a.m. TNON had closed at $5.02 the day before. The next minute it ran to $6.65 on 112K shares.
Stop It's 8:17. TNON is at $5.79. A private placement headline came out two minutes ago, and the stock has already traded as high as $6.65. Would you buy here?
Press play: the real Level 2, tape and chart run from 8:14 a.m. and stop at 8:17 a.m. ET for your call.
That minute it hit $8.17, the day's high, on 291K shares. The top did not hold. A push at 8:19 stopped lower, at $7.27, and by 8:22 it was at $5.94.
Faded before the bell
The spike was over before the open. It opened at $5.46, 33% below the high.
The $5.00 bid
On this day a big bid at $5.00 sat under the price for almost three hours. It showed up at 9:40 and peaked near 22K shares.
Stop It's 12:35. TNON is at $5.25. A large bid has sat at exactly $5.00 since 9:40, and the stock hasn't traded down to it since. Would you buy here?
Press play: the real Level 2, tape and chart run from 12:32 p.m. and stop at 12:35 p.m. ET for your call.
That minute the price fell through $5.00 to $4.86. At 12:36:00 the wall was pulled. The low came at 12:38, $4.77. It closed at $4.98, under the prior close.
What to take from it: The $5.00 bid looked like a floor for three hours, then the price went through it and the bid was pulled.
