Core Viewpoint - Goldman Sachs warns that the silver market is experiencing extreme volatility due to ongoing supply chain bottlenecks, with a significant mismatch in silver inventory locations causing price distortions [1][3]. Group 1: Market Conditions - Silver prices have dropped 5.00% in a single day, currently standing at approximately $74 per troy ounce, reflecting an 8% increase year-to-date [1][3]. - The London silver inventory has reached critically low levels, exacerbated by concerns over potential tariffs last year, which led to a significant amount of silver being moved to U.S. vaults [3]. - The current environment has increased the price sensitivity of silver, with a typical weekly demand of 1,000 metric tons now pushing prices up by approximately 7%, compared to the usual 2% [3]. Group 2: Investor Behavior - Despite the significant price increase, investor demand for silver may not be overstretched, as holdings in silver ETFs backed by physical silver remain below the peak levels of 2021 [4]. - The ongoing trend of interest rate cuts and diversification among investors is likely to continue driving up silver ETF holdings [4]. Group 3: Future Outlook - If policy clarity leads to silver returning from U.S. vaults to London, prices may decline; however, persistent policy uncertainty could keep silver in U.S. storage [5]. - Historical patterns suggest that even with clear policy changes regarding tariffs, a significant portion of silver may remain in U.S. vaults, leading to continued extreme market price behavior [5].

Group 1: Airline Ticket Price Trends - After the New Year holiday, ticket prices for various routes have significantly dropped, with some prices as low as 1-2% of the original fare [1] - Specific examples include flights from Beijing to Hangzhou priced at 272 yuan (1.1% discount) and from Beijing to Wuhan at 280 yuan (1% discount) [1] - The decline in ticket prices is attributed to increased capacity, changes in supply and demand, and competition from high-speed rail [1] Group 2: Train Ticket Price Trends - Train ticket prices have also seen reductions, with specific routes offering significant discounts, such as the D128 train from Zhengzhou to Shanghai at 170 yuan (5.4% discount) [2] - Other notable discounts include the G8111 train from Shenyang North to Changbai Mountain at 206 yuan (6% discount) and the C2725 train from Beijing West to Xiong'an at 65 yuan (6% discount) [2] - The trend indicates a broader reduction in transportation costs across both air and rail travel [2]

Quantitative Models and Construction Methods 1. Model Name: Predatory Trading Game with Disinformation - **Model Construction Idea**: This model incorporates disinformation into a predatory trading game framework, where participants act based on distorted information, leading to deviations in equilibrium and market volatility[3][16][23] - **Model Construction Process**: 1. The model builds on the microstructure frameworks of Carlin et al. (2007) and Carmona & Yang (2011), introducing a victim (forced to adjust risky asset positions) and predators (seeking profit from the victim's constraints)[23] 2. The trading rate of participant \( n \) is defined as: $$ X^{n}(t) = X^{n}(0) + \int_{0}^{t}\alpha^{n}(s)\mathrm{d}s \tag{1} $$ where \( \alpha^{n} \) represents the trading rate, constrained by: $$ \alpha_{t}^{n} \in \mathbb{A}^{n} = \left\{\alpha_{t}^{n} \mid \mathcal{H}_{[0,T]}^{2}, X_{T}^{n} = 0 \right\} $$ 3. Temporary price impact is modeled as: $$ P_{t} - X_{t}^{0} = \lambda \sum_{i=1}^{N}\alpha_{t}^{i} \tag{4} $$ where \( \lambda \) is the elasticity factor[24] 4. Permanent price impact is expressed as: $$ \mathrm{d}X_{t}^{0} = \gamma \sum_{i=1}^{N}a_{t}^{i}\mathrm{d}t + \sigma\mathrm{d}W_{t} \tag{5} $$ where \( \gamma \) represents market plasticity, and \( \sigma \) is the volatility parameter[24] 5. Participants aim to maximize profits: $$ J^{n}(\mathbf{\alpha}) = \mathbb{E}\left(\int_{0}^{T}\alpha^{n}\left(X_{t}^{0} + \lambda\sum_{i=1}^{N}\alpha_{t}^{i}\right)\mathrm{d}t\right) \tag{8} $$ 6. Disinformation is introduced as a random distortion \( \tilde{x}_{0,1} = x_{0,1} + \epsilon \), where \( \epsilon \) represents the distortion[27] 7. The price process under disinformation is given by: $$ X_{t}^{0} = X^{0}(0) - \frac{1-e^{-\frac{N-1}{N+1}\frac{T_{T}}{\lambda}}}{1-e^{-\frac{N-1}{N+1}\frac{T_{T}}{\lambda}}}\gamma\left(\sum_{i=1}^{N}x_{0}^{i}+\bar{\nu}\right) + \frac{e^{\frac{T t}{\lambda}}-1}{e^{\frac{T t}{\lambda}}-1}\gamma\bar{\nu} + \sigma\left(W_{t}-W_{0}\right) $$ where \( \bar{\nu} \) is the error factor[30][31] - **Model Evaluation**: The model effectively captures the impact of disinformation on market dynamics, highlighting its role in amplifying volatility and disrupting equilibrium[16][30] --- Model Backtesting Results 1. Predatory Trading Game with Disinformation - **Maximum Price Fluctuation (MPF)**: $$ MPF_{\nu}(t_{*},t^{*}) := \operatorname*{max}_{t_{1},t_{2}\in[t_{*},t^{*}]}\left|\mathbb{E}\left(X_{t_{1}}^{0}-X_{t_{2}}^{0}\right)\right| $$ The model demonstrates that disinformation increases MPF, with a lower bound determined by: $$ MPF_{\tilde{\nu}^{*}}(0,T) \geq \operatorname*{min}_{\tilde{\nu}\in\mathbb{R}} MPF_{\tilde{\nu}}(0,T) = \gamma\sum_{i=1}^{N}x_{0}^{i} $$[34][37] - **Error Factor Impact**: The error factor \( \nu \) significantly influences price trajectories, with higher \( \nu \) leading to greater volatility[30][33] - **Tolerance Thresholds**: The system tolerates disinformation within specific boundaries \( b_{1} \) and \( b_{2} \), beyond which volatility escalates[38][40] --- Quantitative Factors and Construction Methods 1. Factor Name: Error Factor (\( \nu \)) - **Factor Construction Idea**: The error factor quantifies the degree and spread of disinformation in the market, serving as a key determinant of price volatility[30][33] - **Factor Construction Process**: 1. Defined as: $$ \tilde{\nu} := \frac{N_{w}}{N}\left(\tilde{x}_{0}^{1} - x_{0}^{1}\right) $$ where \( N_{w} \) is the number of misinformed participants, and \( \tilde{x}_{0}^{1} - x_{0}^{1} \) represents the distortion magnitude[30] 2. Generalized for multiple distortions: $$ \nu := \frac{1}{N}\,\sum_{l=1}^{\kappa}N_{w_{l}}\left(\bar{x}_{0,w_{l}}^{1} - x_{0}^{1}\right) $$ where \( \kappa \) is the number of distinct distortions[56] - **Factor Evaluation**: The error factor effectively captures the interplay between disinformation magnitude and its spread, providing insights into its impact on market dynamics[30][56] --- Factor Backtesting Results 1. Error Factor (\( \nu \)) - **Maximum Price Fluctuation (MPF)**: Higher \( \nu \) values correspond to increased MPF, with a minimum threshold determined by: $$ MPF_{\nu}(0,T) \geq \gamma\sum_{i=1}^{N}x_{0}^{i} $$[34][37] - **Tolerance Thresholds**: The system tolerates \( \nu \) within boundaries \( b_{1} \) and \( b_{2} \), with specific dependencies on market parameters and game duration[38][40] - **Dynamic Evolution**: The tolerance for \( \nu \) increases over time, reducing the potential for disinformation to amplify volatility in the long term[90][91] --- Additional Insights - **Information Updates**: New information can mitigate the impact of disinformation by adjusting the error factor \( \nu \), with the timing of updates being critical to minimizing volatility[84][92][95] - **Randomness and Misjudgment**: Random price movements can lead even informed participants to misjudge their information, complicating the detection and correction of disinformation[100][101][103] - **Profit Implications**: Disinformation affects profit expectations, with informed participants benefiting under certain conditions, while widespread disinformation can erode these advantages[49][51][56]

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The global sugar market is in a state of oversupply, but concerns about a decline in Guangxi sugar production may support domestic sugar prices. Zheng sugar short - positions are advised to exit and wait and see [3]. - The supply pressure of pulp is gradually easing, and the cost of new warehouse receipts is rising, which is expected to drive up the bottom of the futures price. However, due to high inventory and weak paper mill profits, it is difficult to form a trending upward market in the short term. Short - term operations can consider long - positions at low levels in the range [3][4]. - The spot price of offset paper remains stable, and the futures price may fluctuate with the basis. As the basis narrows, the upward space of the futures price may be limited. Consider short - positions near the pressure level [5][6]. - The global cotton supply is abundant, and the domestic cotton market is a game between strong expectations and weak reality. The short - term supply is sufficient, but there is a long - term support due to the expected decline in planting area. It is recommended to hold long - positions in the 05 contract cautiously [9]. - The apple 05 contract is facing a game between supply decline and the off - season of consumption, maintaining a high - level range expectation. It is recommended to adopt the idea of buying on dips [10]. - The market's expectation of a decline in jujube production has cooled, and the consumption season is approaching. Aggressive investors can consider short - term long - positions in the 2609 contract near 8900 - 9000 points [11][12]. 3. Summary According to the Directory 3.1 First Part: Plate Strategy Recommendation - **Apple 2605**: Recommend buying on dips. The new - season output, good - fruit rate, and peak value have declined year - on - year, but the driving force for consumption growth is insufficient. The support range is 8800 - 8900, and the pressure range is 10000 - 10200 [20]. - **Jujube 2605**: Recommend short - term long - positions at low levels. The expectation of production decline may be gradually reflected in the far - month contracts. The support range is 8500 - 8600, and the pressure range is 9500 - 9800 [20]. - **Sugar 2605**: Recommend temporary waiting and seeing. The international sugar supply is sufficient, and the domestic sugar - cane pressing season is underway. The market is worried about the decline in production and sugar - making rate this season, weakening short - position confidence. The support range is 5000 - 5030, and the pressure range is 5300 - 5330 [20]. - **Pulp 2605**: Recommend long - positions in the range. The futures price has risen above the price of the main physical delivery product, increasing potential delivery pressure. There is limited improvement in the fundamentals, but there is support below. The support range is 5300 - 5400, and the pressure range is 5600 - 5800 [20]. - **Offset Paper 2605**: Recommend temporary waiting and seeing. Raw material fluctuations affect the price of offset paper from the cost side, but the spot price is stable, and the futures price may operate within a range. The support range is 3900 - 4000, and the pressure range is 4200 - 4300 [20]. - **Cotton 2605**: Recommend holding long - positions cautiously. The external market is operating at a low level, the domestic market expectation is positive, and the long - term bullish expectation is strong. The futures price is expected to move up. The support range is 13500 - 13600, and the pressure range is 15400 - 15500 [20]. 3.2 Second Part: Market News Changes 3.2.1 Apple Market - **Fundamental Information**: In November 2025, the export volume of fresh apples was about 121,600 tons, a month - on - month increase of 51.28% and a year - on - year increase of 12.42%.

Report Industry Investment Ratings No information provided regarding the report industry investment ratings. Core Views Tin - Market sentiment has fluctuated recently, causing significant volatility in tin prices. Operation should be cautious, and subsequent attention should be paid to macro - economic conditions and supply - side recovery [2]. Zinc - The lower support for zinc prices comes from the tightening domestic zinc ore supply and low zinc ingot inventory, while the upper pressure comes from the expected supply of imported ores. Short - term prices are likely to fluctuate, and attention should be paid to import profit and loss, TC inflection points, and changes in refined zinc inventory [5]. Copper - The medium - to - long - term fundamentals of copper are good, but in the short term, prices are over - estimated irrationally, yet may remain strong due to high market speculation. Attention should be paid to overseas inventory changes and CL premium changes [7]. Nickel - Recently, the nickel market has been driven by Indonesia's tightening expectations, but the actual fundamentals are weak, restricting the upside of prices. The short - term market is expected to remain strong, and attention should be paid to potential price corrections [10]. Stainless Steel - The fundamentals of stainless steel show slightly eased supply pressure and strengthened cost support, but demand in the off - season is still insufficient. The short - term market is expected to fluctuate strongly, and attention should be paid to news from the ore end and downstream inventory replenishment [12]. Alumina - The market still faces severe oversupply pressure, and alumina prices are expected to fluctuate widely around the industry's cash cost line. The key to a trend - based rebound lies in whether there are specific capacity control policies or large - scale production cuts [14]. Aluminum - Strong macro and policy expectations support aluminum prices, but weakening supply - demand fundamentals and inventory accumulation pressure will limit the upside. Short - term prices are expected to fluctuate widely at high levels [14]. Aluminum Alloy - The cost is the main driving factor for the price of aluminum alloy. The market is in a tight - balance state with both supply and demand being weak. Prices are expected to fluctuate in a high - level range in the short term [15]. Lithium Carbonate - The fundamentals of lithium carbonate remain largely unchanged, with a slight increase in supply expected. The downstream demand has certain resilience but weakens in the off - season. The market is expected to fluctuate strongly, and price volatility may intensify [16]. Industrial Silicon - In January, industrial silicon is expected to maintain a pattern of weak supply and demand. Prices are expected to fluctuate at a low level, and attention should be paid to the implementation of production cuts [17]. Polysilicon - Polysilicon spot prices are stable, and futures are oscillating at a high level. In January, demand is weak, and prices are expected to remain in a high - level oscillation. Attention should be paid to production cuts and price adjustment acceptance [18].
