An investor that's not greedy is a philanthropist. The market hasn't changed any, you can sell just as they can short.
If the company cared about the stock price at all they'd find a way to stop the bleeding. Instead they leave retail investors complaining to FINRA, running back-alley investigations into 'naked-shorting', and finding every excuse imaginable to rationalize the price action until the next quarterly. If the next financials don't impress, how long do those loyal to the stock plan to keep the campaign going?
