There is always a “fundamental” argument whenever we see bubbles; otherwise, it would be too difficult to convince everyone to pile in.
Obviously, we should be looking at alternative energy sources and reducing our consumption…but that’s just common sense.
I vote for a commodities bubble as it relates to the dollar decline. It may well continue if nothing is done to save the dollar, but what would happen if we get a Volcker in there (we can hope!)?
