I was looking at what Alex Waislitz of Thorney Opportunities Ltd was saying about fxj on 22.6.17 or thereabouts. He was saying Domain's potential makes fxj worth $4b. At the time fxj was 1.215 giving MC of $2.8b.
$4b would give SP 1.73.
Again if all the value in fxj is Domain this would give post split Domain 6.92 Fxj 1.04.
