ASX Today, page-2834

I see what you are saying, and often wonder where the SP would be if it were just sole listed.
Perhaps it would just jump around more. Maybe the dual exchange just gives us each a tempering of our own exuberance.

Anyway we'll never know.

You'd need to ask DW & co about any clear benefit of a Nasdaq listing as they seem pretty keen. Certainly new money! Those yanks are an introspective lot, with not much visible outside their backyards.

Oil is the key factor that we have zero control over. Brent (and WTI) seem to be in a state of flux at the moment, with the traders not sure where the trend will settle.
On the plus side, despite an ordinary 24hrs for it, contango is as strong as it's been for a long time, so the theme should be up.
