You may be right, i thought that the 1.155 wall was taken out around 3:30pm.
Unfortunately I cannot confirm on that as my commsec app is only showing me the last 100 trades.
But wouldn't surprise me if someone was trying to keep it down. After all, I believe those who sold off for tax purposes would want their shares back next week. At least some of them would.
