I love a good conspiracy theory part 2
The new 5% holder- Sand Grove Capital Management LLB is a London based 'Event based' Funds investor servicing UK based customers- see its website.
Greenstone Resources (16.6% AVB owner) is London based.
If Greenstone bought another 5% of AVB it would exceed 20%.
I am not a Lawyer but we have the 20% rule which limits investments over 20%.
I wonder what this could mean? If they breached 20% would that have constituted a takeover bid by Greenstone?
Or is Sand Grove, as an 'Event Investor'- merely investing in this takeover 'event' to make profit?
The above theories suit me much better that the alternative: that the new investors are somehow working in the interests of OZL.

lets hope this is a signal that the takeover will not be a smooth as Mr Cole said it would. Cheers.
Stand Firm- do not sell!
