Britain's vote to leave EU passes with ~51.8%

Correct me if I'm wrong here but wasn't the vote an opinion poll that isn't legally binding whatsoever?

Now the media is reporting it like it's fact and they're tanking the economy over there because everyone is trying to get out

This creates an opportunity for shareholders to move in and buy up the low value stock before it stabilizes.

Now I'm not too sure here, but if I wanted to make money by destabilizing an economy, I'd do what they just did.

And then when things finally stabilize and they vote to stay in, have everyone pull their money out, destabilizing it once again.
