In late April, I established the Kass Model Portfolio, intended to reflect the general construction of a model long-only portfolio with a six- to twelve-month investment horizon. My hypothetical portfolio depicts positioning relative to

S&P 500

industry benchmarks and weightings.

As promised, today's opening missive updates a major change in the portfolio -- a near-doubling in the cash component of the portfolio from 15% to 29%. I am also reducing credit -- which has had a very strong rally in price -- from a 20% weighting down to a still-high 15%.

I view the investment mosaic as a scalene triangle (though in its complexity it is more like a quadrilateral pyramid!), with the angles of that triangle representing fundamentals (substantially the highest weighting), valuation (second-most-important weighting) and sentiment (the least important weighting).

Four factors suggest that the U.S. equity market is now vulnerable to a decline of 5% to 10%.

  • The scope and duration of the recent market advance seem to have discounted a second-half production boom.
  • An uneven and shallow economic recovery that could double-dip in early 2010, coincident with higher interest rates and a hike in individual tax rates, is becoming more likely.
  • We're seeing some early signs of emerging technical deterioration.
  • Bullish sentiment is rising.

In conclusion, above-average cash positions should now be held in light of a possible market correction and in order to have excess reserves to capitalize on opportunities available in a volatile trading environment.

Finally, I have included a shopping list of individual stock candidates (by sector) that could be considered in the aforementioned Kass Model Portfolio.
