Hmmm...this is how the GM shares developed over the PAST 10 years...
So what if the guys 10 years ago thought the same?
It's always a risk...and looking at these numbers the downfall was only
in 2008, the average lies at 30 $. So chances shouldn't be too bad that it raises at least to 15 $ again. So that would be a win of 520,83 %
PS: Judging by that graph, the best buying time is Winter and selling time in summer.
