manipulationinteresting to see whats going on with National today. looks like they are selling within the house and taking the price down a couple cents at a time as they do so. likely be back on the buy next week as they shake out the weak hands. new spin on shorting. if this is happening it can be considered manipulation but there are no regulators with any guts so I don't imagine they worry much. could even be a couple brokers within National. may not be sanctioned by National but the company likely doesn't care as they make a few bucks anyway.
