The model appears to be in good company as I see that Ken Heebner has also put on an inflation bet in his portfolio. Heebner is a portfolio manager with a terrific long term record (though he has struggled in the last couple of years). He has a "swing for the fences" style and tends to make big top-down bets.
I reverse engineered his macro bets and my analysis shows that Heebner has positioned his CGM Focus Fund portfolio for a commodity inflation environment. He is at an overweight position in Materials:
By contrast, he is underweight in Utilities:
...and has an implicit short position in the US long bond:
Long commodities, short bonds and interest sensitives - that sounds like a commodity inflation bet to me.
