Hi Eggman,
Very high trading volatility can skew the correlation between the ETF and the underlying item it is tracking. Now I don't know about your specific situation with DXO and oil, but that can explain sometimes when an ETF does not move in the correlated (or inverse) direction / amount you would expect.
Another thing to look at is what exactly is DXO value based on. It uses the DB liquid commodity index and light sweet crude. So when you saw oil up or down whatever it was, were you looking at WTIC light sweet or maybe something else like CBOE oil or another oil tracking index. Just a thought, don't know if it helps.
I was looking at WTIC
