There seems to be a lot of commentary that the share price will pop upon the commencement of production.
It is well known in the market that production will be commencing within a matter of months.
For all those that know the markets well, the market prices a company based on future events.
So why is this not the case with LMG?
Can anyone give me an example of a company who’s share price has popped upon achieving a milestone that was expected?
Don’t get me wrong, this company has exciting potential.
Does the market doubt that this will all proceed?
There are numerous companies with a market cap of $1 billion plus but are yet to earn a dollar.
Look forward to feedback.
