Dataroma's opinion:
We strongly disagree with Mr. Einhorn's views on gold (who are we to disagree with David Einhorn? True, but nevertheless, we would still like to state our opinion). He states that gold is money (currency). It is not. It's a greater-fool-investment. It seems he is mesmerized by the glitter!

It is possible that gold proves to be a good investment over let's say the next 5 years. If it were to double from here, that would amount to a 15% annual return. But, it could also halve in value since it has no earnings to provide any kind of valuation support. It's worth whatever people think it's worth! Remember, it was a third of today's price, only 5 years ago!
