1. Speculations (e.g. Takeovers, Splits etc) and manipulations (e.g. Director buys a small quantity).
2. Retailers get panicked and start buying shares and share price will go up (e.g. PAP)
3. Suddenly Directors and big players start selling stocks at huge profit.(e.g. PAP, FLCH)
4. Retailers get panicked because Directors have sold their stocks and start selling shares at a loss.
5. Share price will go down further and further
6. Again Directors will buy the shares at a huge discount.
7. Retailers start buying shares again. Reason because Directors and big players are buying and hope something good will happen.
8. Share price will start going up and big players will sell their shares again at a huge profit.
This will go on and on. I can sense that Directors will start buying PAP and FLCH again when those shares go further down. Maybe BLUE is still at the top of the above cycle and if it also manipulated one we can expect that BLUE also will follow the same. There are some other shares too, are already gone through the above cycle and about to go through. Some very famous names keep on doing this. If you go through the transaction history of some of the shares you will be able to trace this out.
