Just got this after emailing re the GDXJ error..
Dear xxxxx
We have reached out the trading platforms in question for a breakdown of the individual holdings, but yet received a reply. In the meantime, we have escalated the issue to the management and the IOF. Please note that we would need to have clear evidence/source of the ownership structure (preferable from data vendors in a defined way, e.g. from Bloomberg) before we can further review and decide if a change is needed. All the information and changes will be announced on our website. Thank you.
Kind regards,
Mirela Stefanova
