Nikkei plunged – is a co-ordinated of speculators (The powered minority)

From record high to one of the largest one day drop since 1987.  We are seeing global market is increasingly volatile and not making sense.  A light increase in rate by BOJ and defend used massive lot of money.  But looks like the minority powered speculators may have win the war this round.  Regulators should have more eye instead of free market mentality that allows scenario like this.
