No doubt about the pump and dump, some big investors are manipulating AIG shares to the CORE. We all know AIG is worth more than the current PPS.
The moment longs sell their shares you will see lot of upgrades and and stock will be back to 50s again. At this point MMs are trying their best to squeeze the longs and also forming a bear trap just exactly opposite to what they did when AIG was trading in higher 50s.
Big institutions are making money on both sides of the trade at the cost of small investors.
