Jason Goepfert of sentimentrader.com ^[1] noted the following statistics regarding Window Dressing, i.e., mark ups for the quarter-end (as reported by Rev Shark).

Markups tend to take place in the stocks that have been the best performers during the quarter (all data refer to Q3):

Number of of S&P stocks up more than 20% during the quarter: 35
Number that showed a gain in last three days of quarter: 28
Percentage of stocks that showed a "markup": 80%
Number of S&P stocks down more than 15% in the quarter: 30
Number that showed gains in last three days of quarter: 14
Percentage of stocks that showed a "markup": 47%

So, there is some statistical evidence that strong stocks saw quarter-end markups Q3, while the weaker ones did not.
