Again you've avoided the question ... Have the failures of management to date been fact or fiction ?
And I don't know which "non-holders" with a sentiment of "sell" you are referring to specifically but I can confidently assure you that they are holders from the past that have much better grip on the performances of management than perhaps you do. Amusingly, many are also those that you would have embraced as "uprampers" previously, myself included ... but something made them change their impressions and I'm confident it's not an "agenda".
Irrespective, their opinion is just as worthy as yours and, who knows, they may be planning on buying back in when management either lifts their game or there is a change ... but it's not for you or me to judge them on their plans - they are just as entitled to a trading strategy as you or I.
imo what you should be attempting to do if you truly believe the comments are fiction is highlight where the falsehood is .... so again, take all the time you need; educate us downrampers why our bad "behaviour" is so wrong and what the real facts about management are. We're clearly missing all the positivity that you can see (pure speculation of course as you've offered nothing yet about their positive performance to counter the negative assessment many have .... could it be that perhaps it's you that is making fictitious claims? ).
