The question one needs to ask themselves based on the evidence not what they claim has management delivered.
To me the answer is no they have not.
The next question would be, am I willing to take the risk that they never deliver againt the low chance of success, well if one remains invested then the answer must be yes.
So it comes down to risk v rewards.
Risk is you lose your money, if you lose your money do you have any capital gains to offset the lose against if not can you afford the lost.
What is the possible rewards, well this would depend on your trading plan, what is your get out price, what does success look like and how high would that push the sp or what dividend would be paid per share.
To me shareholders are entitled to an opinion whether its negative or positive.
