GRML, September 18: a dead regular session, then $4.82 after hours
GRML barely moved in the regular session, then ran to $4.82 after the close.
What happened
Draft for review. Not published.
A quiet open
Almost nothing traded before the bell. It opened at $2.99, one cent above the $2.98 prior close.
Stop It's 9:32. GRML is at $2.98, level with yesterday's close of $2.98. It opened at $2.99 and traded between $2.95 and $3.00 in the first minute on 4,714 shares. Since then it has gone quiet: no trades at all in the 9:31 minute. The pre-market high was $3.02, and the float is 4.36 million shares. Would you buy here?
Press play: the real Level 2, tape and chart run from 9:29 a.m. and stop at 9:32 a.m. ET for your call.
It stayed quiet. The regular-session high came at 9:49, just $3.04, on 310 shares.
A slow slide
The rest of the day leaked lower. It closed at $2.85, down 4%, on just 91K shares.
The after-hours run
On this day the real move came after the close, and before any news. From 5:19 p.m. it ran from $3.03 to $3.84 in two minutes. The Greenland security-deal headline hit at 7:03. The high was $4.82 at 7:12, up 62% on the prior close. After hours traded 2.4M shares, 26 times the regular session.
What to take from it: On this day the quiet session hid the move: it all happened after hours.
