Seems to have traded in the exact same way since last report as since the one before.
1. No massive rise on release of results
2. Steady progression up 10-15% days following release of reports
3. Correction back down 5%
4. Trade flat till next report.
All we need now is a 10-15% fall and quick recovery a month or so before next report is due and you'd swear you'd seen this before.
