I disagree we all know who has been sending the pm's around trying to entice selling. They are doing it for their own personal gain so they can flip the stock up on news.
You are right. Sure there is some manipulation but the trend is also clearly due in part to eroding investor confidence. There are some large shareholders unloading significant portions of their positions.
Investor sentiment is contagious.
Take the bad with the good. If BHEL can do what they say and back it up soon this will turn around. I know, I know that is a big IF.
