Around Aug/Sept 2017, I think that it was announced that ISO standards would be brought in, or reviewed. Both the Haydale graph and that of AGM showed drops at about the same time.
Although HAYD don't produce graphene, an Iso announcement could affect their suppliers?
Thats the only thing that I can think of, around that time, that could have an effect on more than one company.
