Maybe a bit off subject (I don't have pm) but I've been in AMB* for that reason as well. You'll also see it in the NGB* run back in 2012 when it was MDB* (could not post that chart because stockcharts stopped charting it) $GRSO!
The fundamentals certainly do support your statement here. It won't surprise me a bit if at some point GRSO takes off surging. It's only a matter of time now. Looking forward to further news in the not too distant future.
