Markets reaction to Trump's cavalier attitude about DPRK's nuclear threat

I was watching the news yesterday when I heard Trump say "They (North Korea) have been doing this to our country a long time, for many years. And it's about time that somebody stuck up for the people of this country and the people of other countries": http://heavy.com/news/2017/08/trump-north-korea-briefing-statement-get-act-together-trouble-video/

And today we got this tweet from Trump (which appears to be written by a bad action-movie screenwriter):

It's obvious the North Korean regime is getting under Trump's skin. Worst of all, now the Donald thinks his "honor" is at stake. That's a dangerous place to be, for all of us, because Trump is in charge of our nuclear arsenal & he doesn't seem capable of understanding the risks (for example, yes, our nuclear weapons are powerful beyond belief, but even if we decimate North Korea, a nuclear winter would kill us all afterwards).

One (not unexpected) consequence of all this nuclear annihilation talk is the following (A Quartz's article reported it a couple days ago): "Fearing nuclear winter, investors bought Swiss francs":

According to the article, Donald Trump's threat to unleash "fire and fury like the world has never seen" had traders seeking refuge in the Swiss franc because "Switzerland is a rich country with healthy finances and few geopolitical entanglements".

Of course, the health of stocks & currencies would be of no concern whatsoever to humanity if there's a nuclear war. Nevertheless, it is still interesting to observe markets reaction as an early indicator of where we are at this moment in time. According to this NPR article: "Global stock markets ended their worst week in months amid rising tension between the U.S. and North Korea, though U.S. stock indexes steadied on Friday to close up slighlty".

The article adds:

"The Wells Fargo Investment Institute describes the market response, so far, as "tepid." In a note to investors, Paul Christopher, head global market strategist, and Tracie McMillion, head of global asset allocation, suggest, "the threat of a nuclear weapon is certainly more serious than previous threats, but that threat also may increase the probability of a diplomatic solution." They suggest the U.S. and China, a North Korean ally, could work together to de-escalate the situation."

It appears the markets went from the "Trump bump" to assessing "the threat of a nuclear weapon". "More serious than previous threats", indeed. 
But I do hope the strategists are right when suggesting the U.S. and China "could work together to de-escalate the situation". Despite Trump's bellicose tweets, we can only hope more serious officials from the Trump administration make an effort to find a diplomatic solution, and avert a catastrophic war.
