Tweets are rather limited in characters, so my guess is that the auditors email was likely too long to fit in a tweet, but hey that's just my guess. Who knows....maybe this Tweet will also be disappointing?!! That's why I say this is STILL not a done deal until it's signed off....some will sell into a small price rise before the actual news comes (if it does) believing this is just another case of "Roger just made this up" or "This is just another failure to deliver"....etc.
We all have to use the best judgement we can muster and stick with what appears to be the best strategy. That happens to be holding for years for me....Cheers! tuna
