The dollar is at a two-year low and has recently fallen below it's recent trading range which could certainly mean that it's going to take a next leg down. A lot of the miners that I follow finally appear to have bottomed and are starting to move up. Couple all of this with the fact that now even the evil empire know as Golden Sachs has come out and said that due to a continually soft labor market tapering is likely off the table until March of next year.
If I were short gold and/or the miners I would certainly take my profits and move onto the next trade. There is no reason to get greedy when you have already won.
