One of the popular arguments is that markets are in the midst of a bubble being inflated by the Fed, and for a long time, proponents of this argument pointed to the strength in hard assets (gold, silver, industrial commodities) as proof of that the whole rally was about a flight from debased currency. But as these divergences exacerbate, and commodities continue to weaken (as stocks make all-time highs) these arguments look more tenuous, to say the least.
