Can the model results be achieved?
Yes, real returns can be very close to the model returns. Brokerage fees and margin interest (small, but definitely negative) have not been factored into the model (note: shorting on margin does not cost anything). Neither have money market dividends been factored into the results (positive, but very small). Brokerage fee rates are the primary factor that could cause underperformance. Please consider the percentage of each trade that is taken up by commissions for your particular brokerage. Our listed returns use the price of QQQQ when the email is sent out as the basis for our returns. Your execution price may be better or worse depending on the timing of your trades. Any difference should average out over the long term.
