You may have some thoughts on the ASX indices, particularly the AOI and ASX200 regarding how they are structured. I believe the influence of News Corp and Telstra on the indices are too much in that 40% of NCP and 51% of TLS shares are not available for trading yet they are included in the weightings. Is the ASX looking at excluding these untraded shares from the weightings?

As I understand it from reading the AFR, S&P are planning to gradually introduce changes that will take out of the weighting of ANY stock that has parcels that are locked up and are not traded. You should be able to get more information on this from S&P. Look on their web site for a start. There will also probably be something on the ASX web site.
