There's lots of factors at play here, it could be brexit related because the beachs have become soiled so people go to Europe for a break, we dont know who is invested in Thames water, are these british pension funds or other types of investors. Is this a sexism thing, what with a female ceo, has she been wrongly advised, manipulated with data presented in a particular way.

There's so many factors potentially at play here and some of it we wont get to ever know about, but life has taught me there is manipulation in many guises.
