They're saying the current run is long in the tooth and could end soon, so watch carefully.
For what it's worth, I happen to agree - also, the seasonals are about to turn negative (gold typically peaks in mid - Jan). Silver peaks in Feb., platinum in May. Seasonal trading doesn't always work, but it's been working pretty good for the PMs this season. I hope I'm wrong, but I don't think gold is going to make a new high anytime soon - probably consolidate until the fall.
