Uranus is creeping toward ingress into Taurus, which, as I have posted earlier, I consider to indicate a downturn in the economy and the financial markets; also, the Sun, now in its detriment in Aquarius, conjoined the South Node over the past couple of days (the SN also in Aquarius)-since the Sun is a significator for stock exchanges (re R. Bills), I think this is a proximate cause of the sudden significant drop in share prices over the past few days; also the international value of the US$ has been declining over the past month, while several foreign currencies have had equivalent gains-thus drawing investment funds toward other (foreign) markets and away from the US stock market.
Ultimately I consider the current situation to be the first signs of the effect of the August 2017 Solar Eclipse, as I have discussed in earlier posts regarding my opinion on economic implications of that Elicpse.
