I'm not sure your evidence is as clear as you think. Over the last 5 days it is "unchanged". Most of the price move came in the first week.
The CEO's hinted "merger" comments such as "exponential" do make the SHOM $value/share unclear to anyone.
It would be easier (for me at least) if there were a few really comparable companies that could be compared against SHOM's particulars, but nobody has identified any thus far (unless I missed something). The article you referenced about some larger acquisitions did not include details other than the total price paid.
I remain very long SHOM (longterm), and hope it surprises me and makes it to the moon with Alice.
