Well the chart is very clear, and the mechanical progress of SP500 has proven itself for the last 4 years. Therefore before the end of the tappering process, we may very much be faced with such a scenario. To be confirmed of course.
even worst.... We may face a string correction rather then a lighter correction because the progress was above all expectation and too strong.. Still 1880 would be a mininum, 1840, a normal correction, 1820-1780 a sign a reversal
