RE:Fighting against a stacked deck...Margin works both ways. I imagine short positions are made with a certain amount of borrowed money too. NDM went very far very fast. There is monumental possability here, but to quadruple your investment from here may take a couple years. The quick risky buck is what short campainers count on shaking out. The exciting thing remains that shorting is also risky to the shorters. As greed snowballs into euphoric shorting and a plethora of unfounded "news" articles the risk balance begins to favor holders. The best way to alter the formula the shorters work with is to deny your shares to them. See "Join the squeeze campaign". The risk of volatility is high as both sides have support and plenty of ammo comming to the front in the next month. Don't buy on margin. Buy small amounts on sharp dips like this. Watch the short position trend for reversal on rising price and join the squeeze.
