"Maybe this presentation is what has ignited our stock or is it just the NR?"

I conclude that the price rise this morning must be due to the news release. Had it been due to the meeting then the price would have continued to rise or at least held on the rise. Sp is now dropping towards the opening price.
My justification for that opinion is that large investors would not have been content with just a few shares but would continue to buy for a couple of days or until they obtained a fair number of them.
