your secodn paragraph tells me you agree with the statement price and interest go up with a major announcement. Please disaggregate that thought - first comes the positive announcement, second comes incremental interest, third comes increased price. reseearch coverage from a brokerage drives more interest - for all the people who are not seeing the first announcement - this is a second level of incremental interest.

At the margin, you are dealing with supply and demand. In the absence of demand there is no increase in price. demand is driven by interest in teh stroy. End of argument. - you can agree or disagree.
