I don't know how often you have taken the trouble to ring management and speak to them yourself, but if you had, you would know management cannot and will not give any "specifics" … They are not permitted to - as you well now. However, you can get a sense of things sometimes and asking different questions and discussing matters can give one a sense of activity.
… For you to say one "needs evidence to substantiate there(sic) claim" is therefore a nonsense ignoring the realities and exactly what I referred to above re the angry mob … So I respectfully suggest, as a large shareholder, ring 'em up yourself if you've a mind. You may find management agreeable and helpful as I have done in the past. Just because a thing has not (yet) gone according to Hoyle, does not mean everyone is taking rubbish and aiming to deceive. If this is your listening standpoint that is a pity and who will you ever give the benefit of believing?
