It may also be that someone who aquired a lot of shares lately has dumped enough to drop the price enough to set off stop loss orders and is buying them back cheaper than original price. For every sell there has to be a buyer.
DRYS posted a loss and missed expectations yesterday so expectations are not good for the NM earning report on 11/19. Nothing has changed in regards to the long term outlook of NM or NMM, so if you are long I think this may be a great opportunity to add.
there is not a smidgeon of news w/in company. have checked and am confident. this is all ricochet from mindless NMM dump. same happened last Spring to both names, but i think that was more computer generated flash something. was excellent buy point.
