Happened over and over last year to the gold industry. All gold stocks start selling off on a day when it really shouldn't happen. Later that night when the overseas gold markets open physical gold gets sold off. The big market players run the show.
The algorithms get triggered and no stopping it. Morgan Stanley sold 100 share lots to themselves all yesterday afternoon. The only good news part of this was that SMF had well below average volume. Many of the other Mid tiers were at least double their normal volume.
A few more rockets fired into Tel Aviv and we should have a recipe for WW3. Will be good for gold but absolutely nothing else.
Ignore and wait is the only option for investing in any equites.
