I just wonder the motivation of someone who only provides negative commentary on a stock they don't hold.
if you're right and the stock goes to 0 then you haven't made any significant gain in your own portfolio, people may say you were correct, but the opinion of random forum posters on the internet isn't worth a pinch of poo.
if you're wrong , you may have convinced someone else to sell who otherwise would have held onto a bagger.
like what is it that motivates someone to put so much effort into a stock that they have no intention of investing in? What's the motivation?
if someone has done their due diligence then you're not highlighting anything new. You're only wasting your own time
