Research Note: The Structural Disadvantages of Commodity Businesses
An Analysis Based on Warren Buffett's 1978 Shareholder Letter
Executive Summary
Commodity businesses in capital-intensive industries face inherent structural disadvantages that doom them to inadequate returns on capital. This research note examines why these businesses consistently fail to reward investors and identifies the rare circumstances where investment might be considered.
The Fundamental Problem
The structural disadvantage of commodity businesses stems from the fundamental economic principle that when multiple producers create identical products, customers make purchasing decisions based solely on price, eliminating any pricing power for individual companies. In capital-intensive industries, companies must invest heavily in equipment and facilities upfront, but these fixed costs become irrelevant to pricing decisions when excess capacity exists in the market. Since all producers face the same imperative to keep their expensive equipment running to generate any cash flow at all, they will accept prices that cover only their variable costs rather than shut down operations entirely. This creates a race to the bottom where the marginal producer sets the price for the entire industry at barely above their operating costs. The problem becomes self-reinforcing because even though all participants earn inadequate returns on capital, the barriers to exit (including large sunk costs and social obligations to workers) keep capacity in place.
Industry Examples and Evidence
This dynamic plays out repeatedly across various commodity industries, from textiles to steel to basic chemicals, where decades of poor returns fail to drive sufficient capacity reduction. Buffett's textile operation perfectly illustrated this trap - despite equipment carried at perhaps 10-20% of replacement cost, the business earned only 7.6% on its modest book value in a relatively good year. The airline industry provides another classic example where massive capital requirements for planes combine with an undifferentiated service to create persistent overcapacity and pricing at marginal cost. Even in agriculture, farmers with expensive land and equipment will continue planting crops when prices only cover seeds, fertilizer, and fuel, accepting nothing for their land investment or labor. The only exceptions occur during genuine shortages - such as oil during embargos or semiconductors during supply chain disruptions - when pricing temporarily reflects capital employed, but these periods inevitably attract new investment that recreates the oversupply problem.
Investment Implications
Based on Buffett's analysis, virtually no rational investor should invest in commodity businesses with capital-intensive operations, as they are structurally designed to produce inadequate returns on capital except during rare shortage periods. The only potential investors who might consider these businesses are those seeking to acquire them at bankruptcy or liquidation prices well below even the depreciated book value, with plans to either immediately liquidate assets or drastically consolidate industry capacity. Large strategic buyers with the power to permanently remove capacity from the market might also invest if they can create artificial scarcity, though antitrust concerns and new entrants typically prevent this strategy from succeeding long-term. Even Buffett himself, despite his exceptional investment acumen, only remained in textiles due to social obligations to employees and communities rather than economic logic. The clear message is that investors seeking adequate returns should avoid these structural value traps entirely and instead focus on businesses with differentiated products, pricing power, and low capital requirements relative to earnings generation.
Key Metrics from Berkshire's Experience
Return on Capital: 7.6% in textiles despite a good year (1978)
Asset Valuation: Equipment carried at 10-20% of replacement cost
Industry Comparison: 19.4% return on equity for Berkshire overall vs. 7.6% for textiles
Capital Employed: $17 million generating only $1.3 million in earnings
Bottom Line
Only three narrow categories of investors should consider purchasing commodity businesses in capital-intensive industries: distressed debt investors or liquidation specialists who can acquire assets at 20-30 cents on the dollar with immediate plans to cease operations and monetize equipment, scrap value, and real estate. Large industrial consolidators with the financial strength to permanently remove 30-40% of industry capacity and the discipline to not restart it when prices temporarily improve may generate adequate returns through creating artificial scarcity. Government-backed entities or investors with non-economic objectives (such as national security, employment preservation, or strategic supply chain control) who explicitly accept sub-par returns in exchange for achieving social or political goals might also be buyers. Traditional value investors, growth investors, and private equity funds seeking typical 15-20% returns should categorically avoid these businesses regardless of apparent cheapness, as even Berkshire Hathaway with Buffett's exceptional capital allocation skills could only generate 7.6% returns in textiles. The brutal reality is that in commodity businesses, the house always loses and the only winning move is not to play.
