REPLY Meaning of Stock/Level (SD6958)

My humble opinion in relation to the Stock/level discussion, and after my
experience in modelling (specially social matters) is that the consideration
of a variable either as an stock or as a rate is indeed defining the model:
not only the scale but also the approach we are giving to the problem.
I have found often solutions (solutions in terms of a more clarifying
structure, or more straight approach..., not matemathical solutions) in the
model process by changing one of the main variables from stock to rate or
viceversa

This explanation would complete the sentence from George Richardson: 
There's some "art" to selecting stocks, and one sees that by sensing that
some of our practitioners are particularly gifted and insightful in
selecting stocks.
