When the markets think that Hillary is most likely to win, they bet their money into it. However, when the result announced to be the opposite, they panic and fear and sell everything. This was shown as global markets tumbled.
The best is this. After a few hours of the announcement, they realized hat there is no big deal on Trump to be the next president, just like Brexit. They buy again into the markets. Global market staged a huge rally that recovered all the losses and posted even higher before the announcement.
In this episode, the traders lost 2 times.
Welcome to the new world under Trump. It is not gloom and doom but rather a new chapter of order.
