I commented on the extremely negative market sentiment which we are seeing lately due to financial market crisis. The chart below shows almost two decades low sentiment which is now nearly becoming a contrarian indicator.

The current financial market crisis is mostly due to regulatory failure during the last few decades, especially, during the last few years of ARM/subprime bubble and crash after the late 1990s repeal of the Glass-Steagall act, as example. As noted on the article, C.O.P. is addressing the problem of regulatory failure.
