platinum gold ratio, page-6

I was just looking at the long term charts (10 years) on Kitco....

Over that timescale, gold has basically been in a steady uptrend (with a few glitches along the way), and is now bumping up against the all time high of US$1000/oz.

Platinum on the other hand took a massive hit down from highs of >US$2000/oz to the present US$1260/oz or so.

Completely different charts, and obviously completely different supply/demand dynamics. So I'm not sure what a platinum gold ratio is supposed to prove??
