On CAPS, 95% of the 356 members who have rated Natural Resource believe the stock will outperform the S&P 500 going forward. These bulls include Oatflake and mlayfiel.

Just last week, Oatflake tapped Natural Resource as a stabilizing force for your portfolio: "I'm not entirely sure this stock will outperform the S&P 500, but I do think the dividend is a good defensive measure; in combination it should at least be less volatile during down times."

Currently, Natural Resource even sports a P/E of 18.3. That represents a discount to other coal stocks such as CONSOL (25.5), Alpha Natural Resources (NYSE: ANR) (44.0), and Arch Coal (NYSE: ACI) (20.3).

CAPS member mlayfiel expands on the Natural Resource outperform argument:

High oil prices and increased demand from Asia will keep up steady demand for coal, benefiting NRP. In addition, the company doesn't actually mine anything, but rather owns the leases to the reserves and collects royalty payments from the mining companies, meaning that the firm has lower risk in terms of the assets that it must maintain.
