Core Insights - The article emphasizes the volatility risks associated with commodity markets during long holidays, highlighting the need for investors to adopt a systematic risk management framework based on historical data and current volatility trends [1][7]. Historical Review of Holiday Volatility - External market fluctuations during long holidays are driven by three main factors: changes in Federal Reserve policy expectations affecting interest and exchange rates, geopolitical conflicts and supply-demand shocks, and domestic policy expectations coupled with liquidity issues in the spot market [1][2]. - Historical data indicates that approximately 70% of agricultural and black series commodities experience volatility exceeding twice the normal levels in the first week after holidays, particularly in oilseeds, energy, and non-ferrous metals [1]. Specific Commodity Performance Patterns - Oilseeds Reversal Effect: Data from 2010-2019 shows that soybean oil and palm oil have a 60% probability of declining in the five days before holidays, but an 80% probability of rising in the five days after, with average returns shifting from -1.5% to +2.3% [2]. - Black Series Policy Game Characteristics: Iron ore and rebar often face pressure before holidays due to weakened terminal demand, but can rebound quickly post-holiday if stimulated by growth policies [2]. - Non-Ferrous Metals External Drive: Copper and aluminum are closely linked to the London Metal Exchange, with significant price movements observed during holidays due to overseas inventory changes and dollar index fluctuations [2]. Current Volatility Classification and Risk Management Tools - Commodities are categorized into three volatility levels based on 2024-2025 predictions and historical backtesting: - High Volatility: Includes lithium carbonate, shipping, palm oil, and copper, with annualized volatility between 30%-60%+ and expected post-holiday gains over 8% [3][4]. - Medium Volatility: Comprises PTA, rebar, coal, and sugar, with annualized volatility of 15%-30%+ and potential fluctuations around ±5% [4]. - Low Volatility: Encompasses corn, government bonds, and live pigs, with annualized volatility below 15% and expected changes around ±3% [4]. Recommendations for Different Volatility Categories - For high volatility commodities, strategies include reducing positions and hedging with options. For example, a strategy involving "short futures + long spot" can be employed for lithium carbonate [5]. - For medium volatility commodities, buying out-of-the-money put options can be a cost-effective strategy to mitigate risks. For instance, purchasing a put option for copper can cover potential losses if prices drop significantly [5]. - For low volatility commodities, adjusting positions rather than speculating on direction is advisable, such as reducing corn holdings to maintain a base position [5]. Margin Requirements and Leverage Impact - Increased margin requirements for certain commodities, such as coking coal and lithium carbonate, necessitate additional capital to maintain positions, highlighting the importance of managing leverage to avoid forced liquidations post-holiday [6]. Conclusion - Historical data suggests that a significant portion of commodities that experience the highest gains post-holiday are often those that were undervalued before the holiday. The key risk lies in inadequate position management rather than volatility itself. Investors are advised to adjust their holdings towards a mix of low-volatility base positions and options for protection, while maintaining liquidity for potential market opportunities [7].
