mvanle,
I have to repeat again to you that as I said, historically GTP's P/E was usually much less then 10, so applying 10 to the factor of "target P/E" is more than fair enough.
Having a valuation of GTP in this way produces for GTPa valuation of 6.4c/s * 10 = 64c/s.
The present price level of 80c+ is way too high. It's not sustainable.
Full stop.
