I agree there is slippage in 2x funds. that occurs due to very nature of the 2x factor as it goes up one day and down the next. the only way it will match the ndx over any period of time is if the index only went the same directon on each day in the window. and the longer that window is the harder it gets. otherwise its virtually impossible to track the ndx. thats all in the prospectus. i thought calling yourself stupid over that was way to harsh. now shorting the ndx is something to be called stupid over (gg).
