MSS, September 23: a run to $3.16
MSS opened up 33%, ran to $2.95, then gave back most of the run by the close.
What happened
Before the open
We found no news or filing before the move. Before the bell it reached $3.16, on 13M shares.
The open
It opened up 33%, at $2.07. It ran to $2.95 by 11:16 a.m.
The close
It closed at $2.10, 34% under its high.
What to take from it: The high came early. Most of the run was gone by the close, so the move was in the morning, not the hold.
