Holy crap, this is mind boggling. The Brexit poll fluctuation was used for shorting on the British pund. Worth the full read, although you may get a headache from the shananigans being played, and from the amounts of money the players won from gaming the timing. It won’t be the last time.
My question is this: if there are so many players gaming the system, doing some insider trading to nudge ahead of their competitors, what does it indicate about the general health of the economy? The “gaming” is not itself an indicator of the economy, but it does tell me that the economy doesn’t have much to offer otherwise, to investors, to the workers, or to the general public. Not much production going on, just stirring the money around.
