A closer look at GDP
As the chart below shows, the excess returns provided by commodities over cash have historically had a very high correspondence with global gross domestic product (GDP) growth. In short: When global GDP accelerates, commodities have tended to do well - in particular, the more cyclical commodities like oil and copper.
Since the consensus view is that global GDP growth is poised to accelerate in 2014, this historical trend may bode well for commodity investors this year.
Commodity excess returns have tended to move along with global GDP*
Examining bear markets
Looking at the history of bear markets for commodities also suggests that the worst could be behind us in the current bear market.
There have been four commodities bear markets in modern times, starting in 1974, 1980, 1997 and 2008. Right now, the current bear is 5½ years old, and prices are still only half of what prior peak levels were. This is nearly the worst experience for commodities in modern history. That's not to say that prices can't get worse from here, but to assume that the next few years will continue to be poor for commodities is really pushing against market history.
While the current bear market has been tough for commodity investors, I believe the biggest risk would be to exit the asset class, which could cause investors not only to miss a potential upturn, but to lose out on the inflation-hedging benefits that commodities have historically provided to portfolios.
Investors are rightfully concerned with positioning their portfolios to take advantage of the current environment, but I believe they should also look to maintain a diversified core within their portfolio that can help provide resiliency against unexpected events. For example, as the Federal Reserve (Fed) plans its exit from aggressive monetary policy, it's not clear exactly what the effects might be and what could possibly go wrong. Might the Fed taper its asset purchases too slowly and create inflationary pressures? If so, we would expect inflation-sensitive assets like commodities to potentially perform well versus stocks and bonds.
Due to the experiences of the past, combined with the uncertainties of the future, we believe investors should take a constructive view of commodities and the role that they can play in a portfolio.
Specifically, I believe some of the more cyclical commodities, such as oil and copper, represent the most compelling opportunities for commodity investors right now, versus others such as agriculture and precious metals.

Commodities may subject an investor to greater volatility than traditional securities such as stocks and bonds and can fluctuate significantly based on weather, political, tax, and other regulatory and market developments. Commodities may not be suitable for all investors.
