So the company paid for a promotion to tank the stock?
No, as buccaneer has pointed out they paid for the promotion to generate as much retail interest as possible to dump into.
The dump started with 7M volume at close to 04 after the fluffy refinery PR. Once the volume dropped to 1-2M, and the PPS to 03, that's when they timed the paid promotion. The PPS continued to drop, but the volume went back up.
The goal of the insiders is to dump in volume at best price. Where volume is the most difficult thing to achieve and maintain. The promotion has done its job - crank up volume while keeping the PPS in a dump-able range.
Next up, the insiders will suspend the dump. Volume will die, PPS will stabilize, and then start to recover. Cheer leading erupts on forums across the Internet. Then comes another fluffy PR. The retail herd gets excited again. The dump is resumed.
Net result the insiders dump their 100M shares at a cost of 001 for 02-04, for as long as retail demand remains. Who knows where the PPS ends at, with supply overwhelming demand. Afterwards, retail gets to trade among themselves at whatever PPS with flip trades.
