I bought some of this fund primarily because of its low .30 R-squared. I was further influenced to buy when I saw that it offered exposure to asset classes not much present in my portfolio and its potential to do well in times of high inflation. A five-star Morningstar rating for three, five and ten years cinched the deal.
Along the same lines, I have put my toes in the water with the unproven Fidelity Strategic Real Return Fund.
If nothing else, it will be interesting to follow these in contrast to the domestic equity funds that form the bulk of my portfolio.
