just read this on hotcopper - very cool website it is too, excellent layout looks optimised for smart phone / tablet
It should have a 20 and 30 years term too. Since bull>bear markets do happen on those time frames too. Data is out there, why not? Btw about your disclaimer, it's way too conservative lol. I'd make it this: Disclaimer: Invert past performance to predict future performance.
Go right back in history and you'll find the average price of platinum has roughly be the same as gold about 1:1 ratio.
Looking at the current scenario, gold and silver are at pretty low but, expected to outperform in the recent future and so does the investments.
