On the last day of the month or 'Print" day.
All of us sheeple need to feel good about the statements that we all get, well I don't get those anymore, at the close of each month.
They spent the last few weeks of September taking down the lofty earnings estimates and began the qtrly game of selling each other the sacks of crap assets to each other. That way all this crap does not show up on the books as the quarter closes.
They then sell the same shit back to the original holder's at the start of the next quarter. Usually why the mkts are up when a new qtr begins.
