💡 How to read: Higher percentile means crude oil is more expensive relative to the model-implied equilibrium. Full history percentile reflects long-cycle temperature; 1-year percentile captures short-term overheating.
Zone thresholds: >90% (Extremely Overvalued) | 70%-90% (Overvalued) | 30%-70% (Fair) | 10%-30% (Undervalued) | <10% (Extremely Undervalued).

📉 Strategy Backtest & Performance

The following backtest results are based on the full-sample fixed model (reflecting the optimal framework performance). All strategies use the previous day's valuation percentile to determine today's position.

Strategy Rules

StrategyRebalancing Rule
Buy and HoldAlways fully invested, no adjustment
Linear Position (1-Year)Position = 1 - 1-year percentile, constrained between 0 and 1
Extreme Timing (Extreme Reversal)Fully long when Extremely Undervalued, zero when Extremely Overvalued, unchanged otherwise
Pure Long EnhancementGo long on MA(10,30) golden cross, position determined by valuation piecewise function (0.2 to 2 times); zero position on death cross
Two-Way Offense (Shorting)Same long rules as above; 1 time short on death cross when 1-year percentile above 90%
Two-Way Defense (Shorting)Fully long on golden cross when percentile below 90%; 1 time short on death cross when percentile above 90%; zero position otherwise

📌 Strategy Performance Interpretation:

  • Buy and Hold serves as the benchmark, showing crude oil's inherent long-term return.
  • Linear Position reduces volatility and drawdowns through the simple "more expensive → lighter position" mechanism, but with limited returns.
  • Extreme Timing frequently misses rallies in trending bull markets, indicating the risk of relying solely on extreme thresholds.
  • Pure Long Enhancement is the optimal long-only form: trend determined by moving averages, position sized by valuation; it significantly outperforms the benchmark without shorting, proving that the valuation model itself is an effective position enhancer.
  • Two-Way Offense adds shorting during extreme overvaluation, further improving annualized return.
  • Two-Way Defense uses valuation thresholds to filter out longs in overvalued zones and shorts in undervalued zones, achieving the highest Sharpe ratio and smallest drawdown—the optimal choice for risk-averse investors.

Note: Backtests assume zero transaction costs and no financing interest on leverage. Past performance does not guarantee future results. Leverage amplifies losses; practical application requires caution.

📊 Crude Oil vs. Factor Relationships

📌 Chart 1 Interpretation: Over the past 6 years, WTI has climbed from around $60 to 97.29. The valuation percentile shows the current 3-year rolling percentile is 0.1%, in the Extremely Undervalued zone. The real time spread (9.09) far exceeds the synthetic time spread (-0.65), a difference of about 9.7 USD, indicating the market is paying an additional premium for geopolitical risk.
📌 Chart 2 Interpretation: SC and WTI are highly positively correlated, confirming that Shanghai crude oil futures have become an effective mapping of global pricing. VIX is currently 17.71, and its relationship with WTI is shifting from traditional negative correlation to phase-specific co-movement. OVX is currently 57.49, much higher than VIX, indicating that the panic mainly originates from the energy market itself.

📊 Residual Trend

📌 Chart 3 Interpretation: Current residual is -0.1775, in the Extremely Undervalued zone. Residual > 0 means the price is above the equilibrium level implied by the four factors. The current percentile (1.7%) is in the extreme historical region; the model is mainly used for extreme state warnings rather than precise timing.

Factor Explanations:

  • SC (Shanghai Crude Oil Futures): China-U.S. dual-anchor pricing core, a RMB-denominated regional crude oil pricing benchmark.
  • VIX (CBOE Volatility Index): Market-wide risk sentiment, capturing macro fear.
  • Synthetic Time Spread: Constructed based on the forward curve theory using the 10-year TIPS real yield (DFII10), capturing the baseline of carrying costs and convenience yields.
  • China-U.S. Yield Spread: Measures the relative monetary policy stance of the world's two largest economies.

Synthetic Time Spread Factor Explanation:Based on the cost-of-carry model, using the 10-year TIPS real yield (DFII10) to construct the theoretical 3-month forward spread. Current synthetic time spread is -0.65, real time spread is 9.09, the difference reflects a geopolitical risk premium.

Real Time Spread (Verification):Actual contract spread is 9.09, at the historical 98.4% percentile, confirming the geopolitical risk premium.

OVX Crude Oil Volatility (Supplementary):Current 57.49, at the historical 91.7% percentile.

China-U.S. Yield Spread (Factor):Current -0.0325, reflecting the relative monetary policy stance between China and the U.S.
