Model Portfolio Allocation Changes- This Week

Models Shuffle Allocations

Both Model Portfolios have triggered changes at this time. The re-allocations concentrate the portfolios in Largecap stock funds as Mid Cap stocks have finally lost their leadership role in the recent market rally.

Portfolio Changes in the Performance Xtender: The model is selling the previously existing 60% position in a Midcap stock fund and reinvesting the proceeds in a Largecap stock fund.

Portfolio Changes in the Max Xtender: This model is selling the Leveraged Midcap index fund and reinvesting in a Leveraged Largecap index fund. It is also selling the un-leveraged Midcap stock fund and reinvesting in an un-leveraged Largecap stock fund. The net effect of these transactions leaves the model's leverage factor unchanged at 1.5 to 1.

Model Portfolio Details

The tables below provide the percentage allocation details and mutual fund ticker symbols for investors following the Model Portfolios by using funds from either of the Rydex Investments or ProFunds mutual fund companies -- or alternatively, investors using exchange traded funds (ETFs).

'Performance Xtender'

(A model portfolio that invests selectively in stock market index funds, plus certain market sectors such as Energy, Gold and Real Estate, and in an Inverse Fund ("Bear Fund"), depending on current market trends for each type of investment. The allocation mix is designed to beat the market significantly during both bull and bear markets with only limited risk of volatility.)

'Max Xtender'

(A model portfolio that invests selectively in stock market index funds and in an Inverse Fund ("Bear Fund"), depending on current market trends for each type of investment. During strong market trends ... either bullish or bearish ... the model uses up to 2-to-1 leverage to magnify returns. The allocation mix is designed to beat the market substantially during both bull and bear markets but results in a relatively high risk of volatility.)
