MG the spi has been closing 8-16 points under xjo for the last 3 days and today I think spi futures were trading 20 odd points under cash during the normal open session . I will check the exact number tomorrow for u in the live session .
If u still have a cmc platform u will note they have aussie 200 and spi futures . Spi fut's on cmc trade with an extra point in the spread . The aussie 200 is a mix of spi and xjo and they reserve the right to adjust it at their discretion but follows xjo more closely . Spi moves much faster than xjo and spi is adjusted to allow for upcoming dividends in stocks .
When these 3 biggies go ex dividend the fut's to cash markets gap will close up ;http://www.asx.com.au/data/asx_equity_cfds_dividends.pdf
Voltaire used to occasionally put up a chart with the difference in pricing between spi and xjo which showed what months the price would blow out or under the physical .
