precious metals are never a bubble... not totally correct
when they start rising dramatically your watching the fall of that currency...
Attached is a graph of the historical price of silver for the past 35 years or so. As you can see there have been a few drastic swings in this market also
This happened only once. When the Hunt brothers decided to try to corner the silver market. That's why it spiked and then declined.
Other than that, it has just risen.
just like for the record to state that my original observation stands true. that was a very rare thing to see. in this chart you can see the gold silver ratio in motion... gold rises because of the Hunt brothers heavy silver grab...
