On CAPS, 96.5% of the 1,558 members who have rated Rio Tinto believe the stock will outperform the S&P 500 going forward. These bulls include goqqq and Nikobonjon.

Just last month, goqqq noted that Rio Tinto "is one of the direct beneficiaries of the increasing appetite for natural resources." Our CAPS member continues: "Rio's cash flow base is diversified, and the company is less susceptible to changes in the market than single-commodity producers are."

Over the past three years, Rio Tinto has even grown its top line at a brisk rate of 24% annually. That's much faster than competitors such as BHP (6.8%) and Vale (14.3%), let alone Freeport's annual decline of 0.1%.

CAPS member Nikobonjon expands on the outperform argument:

My take on [Rio Tinto] is the continuation of increased commodity prices globally for the next few years. Being a large diversified and reasonably well run company I am throwing my hat into this ring. I also like the balance of the many commodities that this company brings to my portfolio.
