Introductory Context
"Quantitative value factor strategy on Indian commodity futures (MCX Crude, Gold, Silver, Copper) ranking assets by 5-year real production cost discounts."
Fundamental Anchors in Commodity Markets: The Value Anomaly
Unlike equities with corporate earnings, commodities derive fundamental value from marginal production costs (all-in sustaining cost - AISC) and long-term inflation-adjusted historical real price averages. Over multi-year cycles, commodity prices fluctuate wildly above and below these fundamental production cost floors.
The Commodity Value Factor Strategy (formalized academically by Asness, Moskowitz, and Pedersen, 2013) ranks commodities traded on Multi Commodity Exchange of India (MCX) based on their 5-year log-price discount relative to real historical fair value, taking long positions in deeply undervalued commodities nearing production shutdown thresholds and shorting overextended assets.
• The Commodity Value Rule in One Sentence
Rank the universe of liquid MCX commodities (Crude Oil, Natural Gas, Gold, Silver, Copper, Zinc) by their 5-year real spot price discount relative to historical average; long the top-value quintile (most undervalued vs production costs) and short the bottom quintile, rebalancing quarterly.
Mathematical Formulation of Commodity Value
For each commodity i on MCX, the value score (Vi) is calculated as the negative of the log-ratio of current real spot price (Si(t) / CPI(t)) to its 5-year trailing average real price:
- High Value Score (Vi >> 0): The commodity is trading at a steep 30-50% discount to its 5-year average real price, often at or below global marginal production costs (e.g. Copper at USD 7,000/ton or Crude Oil at USD 45/bbl). Miners curtail supply, triggering long-term mean reversion.
- Low Value Score (Vi << 0): The commodity is trading at multi-year peak bubble prices. New production capacity comes online, depressing future prices.
