"Well, if regulation and governance in Australia were good. OMN would be worth more IMHO."
If you really believe that lack of governance in Australia is resulting in more sellers of OMN than buyers, then all power to you.
As for Caltex not being $60 per share, I suspect most strongly that has got infinitely more to do with good old fashioned valuation than it has to do with CTX failing to be like OMN.
