SIL only goes back to its inception around June of 2010, less than three years ago, and we're currently down to an intraday low of $16.15, a price we haven't seen since the summer of 2010. How does one explain this and does Goldman Sachs really have something to do with all this? I like how Jim Cramer sometimes calls them "Golden Slacks." All I know is that the precious metals stocks sector's bullish percent index hit "zero" on Friday when Royal Gold ( RGLD) plummeted more than 4%, to $60.62. Let's look at RGLD's price chart below. It's not suffered as much as others in the sector because it's a royalty-streaming company that, as you can see, has done very well when it comes to its quarterly revenue-per-share growth. RGLD data by YCharts I'm no precious-metals sector expert, but to the best of my knowledge, the last time the gold stock sector's bullish percent index hit zero was in October 2008 and the United States and most of the world was melting down in the worst financial crisis in over 70 years.
