RE: Someone keeps selling 100 sharesYou're talking about the TICK.
You can't short on a down tick, providing you're disclosing your short to the market properly.
Making sense of 100 lots with this stock given the volume it trades is very frustrating and likely impossible to put together what is really going on behind the seens.
What is important over the past few days is that the volume really dropped off, and unfortunately that has led to a decrease in price.
However the industry sector sold off too.
What DTC too for some real questionable trading.
