Meet Mister Market and his mood swings

‘Mister Market’ was coined by influential investor and researcher Benjamin Graham.

In his 1949 book “The Intelligent Investor”
Graham uses the allegory of ‘Mr Market’ to explain the market mood. 

The concept behind Mr. Market is simple.  But the question is :  What is the current mood of Mr Market ?

And is it possible to somehow 'measure' Mr Market's mood ?

It is certainly worth a shot : I designed a Stock Market Mood Model to get a sense of Mr Market's current mood.
