Two recent runners have been SIB and CYD. AHT has a decent sized shareholding in SIB and also 34% of Mineral Resources which has done the Chinese deal with CYD.
It also owns shareholdings in various other companies and has recently finished a share buyback because it had spare cash and believed its own shares were undervalued.
Read all about it in the letter to shareholders dated 30/6/2003.
I happened upon it by chance as I was doing a computer search through the database for stocks which appeared to be bottoming out after a fall. The chart looks quite encouraging.
As usual, all care, no responsibility, do your own research, etc.
