Natural-resources equities are generally an unloved bunch, but is it because they are a bit misunderstood?

Yes, they can be volatile, are tied to unpredictable commodity prices and are a sort of hybrid investment in that they can move with either the commodity or equity markets.

Over the past few years, the S&P 500's exposure to energy and metal companies has dropped by more than 50%, according to a white paper published this month by Jeremy Grantham and Lucas White of global investment management firm GMO.

The paper is appropriately titled, An Investment Only a Mother Could Love: The Case for Natural Resource Equities.

About this time last year, commodity prices were under pressure due in part to an oversupply of oil and a subsequent plunge in prices, a stronger dollar, decelerating growth in China, and disappointing performance in emerging markets. Lackluster commodity-related returns led to apprehension regarding natural resources as either short- or long-term investments.

However, strategists such as James McDonald of Northern Trust asserted that an equities-based approach to natural-resources investing held promise over the long term.

In the GMO paper, Grantham and White argue for natural-resources equity investing based on the following:

  • The growing demand for and finite supply of cheap resources will push up future prices;
  • The diversification that natural resources can provide, as evidenced by low to negative correlations with the broad equity market over long periods, while delivering equity-like returns;

  • Natural-resources equities usually trade at a discount due to their short-term risk, but tolerating short-term volatility can pave the way for long-term out-performance. In fact, over 10-year periods, commodity producers have rarely delivered negative returns;

  • Equity investing offers an inexpensive, liquid manner to access commodities while avoiding the costs associated with related futures contracts, i.e. selling out of cheaper, near-term contracts to purchase longer-term, more expensive contracts.
  • There is an equity premium available because returns are higher than if the investor purchased the raw materials themselves.

Although there are compelling reasons to consider natural-resources stocks, they should be considered as part of a balanced portfolio rather than an asset class to be loaded up on indiscriminately. The first step, therefore, is to find fundamentally sound companies.

Using our Guru Stock Screening models identifies the following six highly scoring natural-resource stocks that deserve a look as potential long-term investments:

1. Cameco  (CCJ) - Get Report
This company is engaged in the exploration, development, mining and sale of uranium as fuel for nuclear-power reactors. Our Joseph Piotroski-based investment strategy favors the company's book-market ratio of 1.15 which, given its positive return on assets (0.74%, up from a year earlier) and its positive operating cash flow of $342.97 million, indicates that the underlying business is sound.

Long-term debt is modest at 0.17% of assets (a slight improvement over the prior year).

This energy company engages in oil exploration, production, refining and distribution. The company earns a perfect score under our O'Shaughnessy-based investment strategy due to its market capitalization of $41.02 billion, coupled with its cash flow of $10.39 a share, substantially above the market mean of $1.39 a share.

Trailing 12-month sales of $83.31 billion meet the requirement of exceeding the market mean of $20.60 billion by 1.5 times. Our Kenneth Fisher-based screen favors the company's price-sales ratio which, at 0.49, is well under the 0.75 maximum.
