as a follow up to my mispricing pair theory, the ndx was off 1.05%, 2x that is 2.10%. so bear fund should be up 2.1 and bull down 2.1. real data is bear up 2.08% or .02% (typical miss) and a positive .12% today on bull fund which is lousy but makes up a large percentage of the -.18% miss yestrday and also over the .10 i speculated it would be today. net miss for the two days combined is -.18 + .12 = -.06/2 =-.03% or jsut outside of the acceptable level.
