Voda Idea - Retrace?? Not so clear

As per weekly chart, the price has come down to 50% of the rise. And, from there it has closed @ 7.8. So, it seems that it may once again go to 8.55. But, what could be the reasons which can trigger this? As read somewhere Sri. RK Damani had entered at 3.8 in a big way. They may get attracted again.
