What is going on with the trading in CGG???
Their management tell me that nothing unusual is occurring in the daily trading of Citadel.
The facts do not support their statement.
Every day without exception there is a pattern of selling down this stock that is becoming highly suspect!
Every trade today is in numbers ending in 926 and then 074 to round off the 1,000.
This same pattern but with different sequences has been occurring for well over 12 months.
Does anyone have any idea who is responsible or just what is going on as this share price is going no where but down whilst this continues.
