In current real world terms this translates to that point on the charts where market sentiment turns decisively from optimism to pessimism.

The concave upwards dome of optimism that for many market participants dates all the way back to the 1950’s is in the process of being demolished, just like the City of Pittsburgh’s iconic Civic Arena. The apex of the dome occurred in the early 1980’s when manufacturing was still a significant force in the economy, before technology had given Corporate America the ability to off-shore, outsource and automate every high paying job that formed the backbone of the middle class.

The charts in this series all depict different aspects of the economic inflection point. Most of the charts are presented in year over year percent change format to illustrate how the nominal highs that many indexes have made recently have been generated by steadily decreasing rates of growth.

In 2008 decades of expansion flipped to contraction as growth rates collapsed to unprecedented levels. In technical terms the housing and banking crash that occurred four years ago was a breakdown where long term growth support levels utterly failed to prevent a sharp drop on the charts. The deflationary drop did happen; the central banks flooded the system with cash, and a temporary reflation of the system was accomplished.

But the fact remains that the manufacturing jobs are gone for good, and without a thriving and reproducing middle class the economy will never be able to maintain a steady rate of expansion. So optimistic expansion becomes pessimistic contraction, and the point at which that happens is the inflection point. As we say in Pittsburgh, that’s where we’re at.
