"Markets brace for 'black swan' impact of US presidential election" was the headline for a business article on RT on Monday.
A black swan event is supposed to be an unpredictable event, a surprise that changes our current reality, that we were not expecting. A curve ball that comes out of nowhere. An example would be the attack on the twin towers, which caught most of the world by surprise and sparked a huge number of changes, from military action to the curbing of civil liberties.
When you have an election with just 2 main contenders, the foreseeable outcome is that one of the 2 candidates will win the election - there is nothing unpredictable about that. Unless you are closing your eyes to the possibility that your chosen candidate may not win, in which case you deserve to be in for a shock.
The financial markets should be prepared for either Hilary Clinton or Donald Trump to win the US elections. If someone else wins, then that would be a black swan. For instance if Bernie Sanders ends up as president, because Hilary is suddenly out of the running, then that would be a black swan event. But Trump winning is a predictable outcome....unless you have rigged the election so that he can't win, which would then make it a black swan if he won.
Reading between the lines the financial markets are warning of trouble, whoever wins the election. You can count on them blaming the presidential election for causing instability, whichever candidate wins.
