I am perplexed .
I have been searching for reasons , why do people post negative things on shares they don't own .
Is it because they view themselves as a savior of all share investors.
People make random posts. with no facts ,When some one replies with the facts, it does not make any different , they just post the same objection again and again.
why are they so concerned whether china will ban a product they are not connected to or that they don't own shares in.
Maybe that they have a some ulterior motive or are just a contentious person.
Maybe they are narcissistic and like to control the emotions of others , trying to trigger a emotional response in others to bring some satisfaction within themselves, seeing someone respond to their post emotionally.
Maybe they are just bullies , most would recognize this type of person from school , workplace or in the family & in relationships.
It is not acceptable anywhere.
What do you think?
