The following 1-year daily charts of major world markets show that some of them have broken below their mid-year lows, while others are close to a retest.
In the following two videos of BNN Bloomberg's August 9 interview with David Prince, it's clear that market weakness is not President Trump's fault, in spite of what many media pundits would have you believe.
As David outlines, there are many factors at play, contributing to economic slowdown, that are affecting markets worldwide.
"New records are being made, specifically with the value of negative-yielding debt (that you basically pay to own) now screeching to $15 Trillion worldwide."
Just glancing at the charts above, I'd say that if the remaining markets break and hold below their mid-year lows, we'll likely see an escalation of, not only worldwide market weakness, but also economic weakness...potentially leading to a recession in the not-too-distant future.
