at a guess...some of the buying may be in anticipation of ASR news... possibly due first week of July... in lead up to 4C report.
looking back at LVT announcement history we see the following sequence...
1st week July 2015(LVT listing from bones of MOU coal stock)... so no ASR news was really practical. but we know ASR was at $300,000 from LVT graph issued in August 26th 2016 presentation.
Friday, July 8th 2016 - $1,000,000 ASR passed
Thursday, July 6th 2017 - $4,000,000 ASR passed
so... back to my guess.... ASR update in this first week of July 2018?
