I read something a while back about how the so-called spike in shorting stocks after the Brexit vote was down to the journalists misreading the data, then this went away for a bit but it's come back now, I'm not sure if it's cos of new revelations but it seems to be the same story.
The thing is, when I worked as a trader, short selling was something you could do as a hedge as well as to bet against a security. For example you might be long calls and so you could hedge that by selling the shares but that would in no sense mean that I was hoping that stock went down. So just cos someone is short a security doesn't necessarily mean they want it to go down. You need to know the whole position before you can work out what they hope, and it might even be something weird that they want it to go down and then go up and they stay at the same level for a month or something.
Also, perhaps more importantly, if you're in finance - if you supported Leave or Remain - you're gonna bet against the pound cos it's gonna go down. That's just common sense. The thing that's hard (for me) to swallow and which will be hard to prove, is that Boris Johnson is pursuing this course to illegally further enrich his already rich mates at the risk of fucking up his career, his legacy and so on. I think he's too selfish to do something so risky to benefit other people. What's it supposed to be that he will gain from this?
Again, I could be wrong, I would love it if he could get caught making a promise to someone that he'll fuck up the country so they can get rich but it seems unlikely.
