4D,
It depends how deep your pockets are and how you much risk you are willing to take. It is you that has to manage the risk. There's lots of upside potential in QEC that could happen at anytime between now and the end of the year and that risk IMHO out weighs the downside risk but only you can decide on what side of the equation you want to be on and how much sleep you want at night. If you can afford to hold this stock I believe it's the 1 in 10 that every investor dreams of owning in his portfolio. I'm sure you've heard this before and maybe it will ring a bell for you.." did you see how much those guys made on ECA?
Cheers
JQ :)
