What makes the present asset rally bizarre is that it is an asset rally. For some reason, all the asset markets (stock, bond, commodity) have been heavily correlated. Furthermore, these markets have also been highly internally correlated.
The author postulates that the market is driven by the outcomes of macro events, the primary driver being central bank money printing.
I think that disappearing randomness and increased correlation in markets indicates broken markets. Money printing is destroying the price discovery function of the markets.
