No I don't know this. And higher volume on a PR day means more buying and selling happening on that day due to the news, and people's reaction to the news including reactions from discussions on message boards like this one. Looks to me like this fell more on the radio silence days after the live online launch than in other time periods where there were PRs.
Yes we have not the many if any pops on pr's which to me is strange as I believe it is strange to others from posts after past pr's. Imo I agree someone is selling into news, but I don't believe it's CGAQ, again I feel it's the 9.2 million Free Trading shares to Quantum ... or some other large shareholder ... and not CGAQ.
