Furthermore, it may appear on this graph that the SP500 could break out to new, never before seen (record) highs but in effect that is nothing more than an optical illusion on a flat surface, i.e. in 2-D space.
In reality it does not matter how much more or how much harder this box/tunnel is twisted (Monetary Stimulus, Fiscal Stimulus, Santa Clause Stimulus, Jesus-and-all-the -Saints Stimulus, all that would accomplish is to "flatten the tunnel/box" even more - thus raise the edges ever farther away from the current SP500 peak - while approaching Infinity - i.e. a Singularity where all value would cease to exist.
