I see this happen more often than not as I look at this stuff five times a week and when the oil markets open on Sunday. If it was every once in awhile, I would agree with you but it doesn't.
In contrast we have the inverted relationship between crude and NatGas: ~ 80% of the time when crude is up, NG is in the red and vice versa. Now THAT is the market. Traders are using one to hedge the other and that's organic.
Dropping a "well timed" news article about inventory numbers I think have been as bullshit as the CPI for years isn't organic. It's manipulation.
