IF (and it is still a big "if") gold has resumed its downtrend, this could be a possible interpretation of the move from the top it made few days ago. It is now showing very tight inverse relationship with SPX, so a relief rally would probably facilitate the decline.
Anyway, it WAS a good shorting opportunity at the time of my first post, and from a low risk opportunity, it is morphing into "no risk trade" (if such a thing exists at all!), i.e., lowering your stops could be in order.
