A Fundamental and Sentiment Framework for Iron Ore Futures
Summary
This commodity research framework organizes iron ore price drivers into fundamental supply, demand, and inventory factors, alongside a separate sentiment category. It discusses practical handling of slower and irregularly updated fundamental data, including aligning frequencies, accounting for publication timing, adjusting for seasonality, and treating outliers. Individual factors are evaluated by sorting observations into thirds to create position signals; the authors report that the resulting t-statistics closely track Sharpe ratios when fees and trading frictions are excluded.
The screening results favor supply and demand measures, changes in downstream prices over their levels, and inventory levels. Shorter sentiment momentum horizons are reported as more predictive than longer ones. A rolling approach combines the factor groups using a 24-month observation window and a half-month investment window; combined strategies are reported to have Sharpe ratios around 1.5. The evidence is conditional on the described setup and excludes transaction costs, limiting conclusions about live tradability.
Key ideas
- Iron ore drivers are grouped into supply, demand, inventory, and sentiment factors.
- Fundamental series require care with frequency alignment, release timing, seasonality, and outliers.
- The study uses tercile-based signals and finds their t-statistics closely associated with Sharpe ratios before costs.
- Downstream price changes and iron ore inventory levels show different predictive strengths.
- Combined factor strategies are reported to achieve Sharpe ratios around 1.5 in a rolling setup, excluding trading frictions.
