Why the disparity between DDM and DXD?

Watching DDM and DXD this morning and see a big difference between the movements in these ETFs. The DDM is ultra long the DOW 30 and the DXD is untra short.

Right now with the DOW down about 60 points DDM is down $1.12 and DXD is only up by .32.

Why the big difference in movement?
