i dont think any index matching funds would have held GBG, it made up such a small fraction of the index that it's performance was irrelevant to the movements of the ASX200. For example you can replicate the ASX200 movements without the need to hold all 200 stocks, you only need to hold 20 or so, plus some SPI contracts and you'll effectively account for the ASX200 movements.

The only way there is any form of "index" type selling is if the fund has a mandate/rule, ie can only invest in a company if it is in the ASX200.

No index matching fund would hold GBG. Would not be worth their while
