if you are talking about the QTimer.com site, there is a tabulation of the trades below the chart that states performance.
For the period 1/18/07 thru 12/24/07 1x returns with qqqq were 8.1%, rydex 2x fund returns were 18.0%, and buy and hope returns holding qqqq for the same period were 18.5% (from 44.08 to 52.24).
To me that is hardly anything to get excited about.
Reports some pretty good returns over a short period. However, like Qtimer the trades are unverified. Appears to be run by someone going by the name of Blasher, who posts at this ihub site
