Squat and Hylton are right...This is the old GM and I can tell you that no financial adviser would recommend it
I would not count on this being a long term investment (which is how a portfolio
should be designed)...Believe me, I had the same idea about 2 months ago and I bought numerous shares of MTLQQ at about .70 and I held on to them for about 2 weeks and sold them at .90 - after they had gone up to around 1.00 a few days prior...It was a very excellent call on my behalf and I made about 30% which is not bad at all...Shortly after they fell again to around .60-.70 and I felt good about myself for not getting greedy or stupid (which, yes has happened with some other stocks...One of them was AM [a greeting card company] a few months ago that I bought at about 6.00 and then I sold at around 9.00 after it shot up 53% in one day and then started a slight decline...It is now at about 22.00 doh! lol)
Oops...I just noticed that that wasn't the example of me being greedy and stupid that was the example of me jumping the gun lol...Another stock I had was WPT and I bought it at 1.18 and it went all the way up to about 1.90 (yep, about 60% growth) and I held onto it...Subsequently the company was acquired by another company and the stock price fell to about .90 lol....Yep, that's my doh! story haha
But anyway, I'm not saying that there is absolutely no potential - just that you need to keep a very close eye on it and I would limit yourself to about 30% then sell and move on
