Central banks have guaranteed a bubble collapse is the only possible output of the system they’ve created.

The psychology of blowoff tops in asset bubbles is fascinating: let’s start with the first requirement of a move qualifying as a blowoff top, which is the vast majority of participants deny the move is a blowoff top.

Exhibit 1: a chart of the Dow Jones Industrial Average (DJ-30):

Is there any other description of this parabolic ascent other than “blowoff top” that isn’t absurdly misleading? Can anyone claim this is just a typical Bull market? There is nothing even remotely typical about the record RSI (relative strength index), record Bull-Bear ratio, and so on, especially after a near-record run of 9 years.

The few who do grudgingly acknowledge this parabolic move might be a blowoff top are positive that it has many more months to run. This is the second requirement of qualifying as a blowoff top: the widespread confidence that the Bull advance has years more to run, and if not years, then many months.

In the 1999 dot-com blowoff top, participants believed the Internet would grow at phenomenal rates for years to come, and thus the parabolic move higher was fully rational.

In the housing bubble’s 2006-07 blowoff top, a variety of justifications of soaring valuations and frantic flipping were accepted as self-evident.

In the present blowoff top, the received wisdom holds that global growth is just getting started, and corporate profits will soar in 2018. Therefore current sky-high valuations are not just rational, they clearly have plenty of room to rise much higher.

Skeptics are derided as perma-bears who’ve been wrong for 9 long years. This is the third requirement of qualifying as a blowoff top: Bears and other skeptics are mocked and/or dismissed as irrelevant.

Meanwhile, observers who haven’t drunk the punch recognize this as the final leg of a 9-year orgy of central bank stimulus. Pump $14 trillion into global financial assets and all sorts of wonderful things happen, especially if the central banks make it clear in public statements that they will “do whatever it takes,” i.e. assets will not be allowed to decline.
