I think your boss is right. If you are creating the model portfolio, and making decisions about the content of the portfolio, then you should be showing actual results. You appear to be talking about subtle changes, but suppose you had an "aggressive" portfolio that was invested in an S&P 500 fund for a year, and the fund lost 20%. If you then change the portfolio to cash, or a short fund, you'd be able to show no loss or even gains on the model. Not in the least bit accurate; it's like retroactively changing the results for a mutual fund by changing the investments to something that "could have been."
