I believe the downward trend in the morning is done by the shrt-term player, they like the tree shaker, pulling the price down as much as they can, this makes the share price looks disastrous and some new-investors will follow the momentum as they believe the company has problems.
Why would they keep selling? Dun they make a loss? No, becuase they will re-enter at a lower price than where they sold it. AM i right?
