I'm expecting (not predicting) a fight back by the bulls tomorrow for 24 - 36 hours, followed by a mauling from the bears. This expectation is based purely on the pattern of the last mini-crash. The current situation looks more serious because the global situation is in deep uncertainty cause by BREXIT, as evidenced by readings on the VIX. Markets dislike uncertainty. People dislike uncertainty. Shareholders will be expected to protect their losses should the expected fight back over the next 36 hours not work. In those circumstances there is likely to be a cascade of selling of stocks globally, as investors look to protect themselves. For the avoidance of doubt my choice of words there is to indicate speculation. Nothing here means that I am predicting what will happen.
