Group 1 - The Hang Seng Technology Index rebounded, reaching 5156.06 points, up 0.91% from the previous trading day, with a trading volume of 11.73 billion shares and a turnover of 32.5 billion HKD, indicating a moderate increase in trading activity [1] - The current PE-TTM of the Hang Seng Technology Index is 21.35 times, which is at a historical low of 26.0% over the past year, providing a significant valuation advantage compared to the STAR 50 Index (165 times) and the NASDAQ 100 Index (34 times) [1] - The market sentiment is gradually improving, as evidenced by the Hang Seng Index rising 0.96%, reflecting a recovery in overall market sentiment [1] Group 2 - The moderate rise in the Hang Seng Technology Index reflects a gradual repair of market sentiment, supported by the AI partnership emphasis from Anthropic, alleviating concerns about traditional software companies being replaced by AI [2] - The Hang Seng Technology ETF (520570) closely tracks the Hang Seng Technology Index and includes 30 large-cap, liquid tech companies listed in Hong Kong, making it a key tool for capturing trends in the Hong Kong tech sector [2] - The combination of low historical valuations, continued inflow of southbound funds, and the acceleration of AI commercialization suggests that the index may continue to experience structural upward movement in the short term, with a sustained recovery logic in the medium term [2]

近期的恒生科技简直是太逆势了，A股上涨的时候恒生科技跌，A股跌的时候，恒生科技反弹力度依然很弱，今天A股三大指数集体调整，而恒生科技指数 仅仅微幅反弹了0.28%，要知道昨天一度大跌了2.87%，这说明即便是重挫之后，资金抄底恒生科技的力量依然不足。 目前恒生科技无论是日线还是周线，都呈现了典型的空头走势，这种情形下即便再有勇气的资金也是不敢随意抄底的。 为啥恒生科技指数今天走势如此的不堪呢？ 从目前的恒生科技指数的走势看，依然处在一个标准的空头排列，比较好的一点是恒生科技指数在5000点之上徘徊，如果是我自身持有恒生科技指数的话， 如果维持在5000点之上，我会坚定的持有为主，如果恒生科技指数失守5000点，意味着一个重要的整数关口没了，那么对之后的投资就要谨慎应对了，这个 时候不仅仅不能加仓，反而应该适当的减仓回避短期风险了。 免责声明：文中内容仅供参考，不构成任何操作建议或提示，股市有风险，投资请谨慎！ 那么，什么情况下才能改变这种现状呢？ 我觉得两点很关键： 其一，外卖大战停止，市场预期会逐步转好，这对大型互联网平台的业绩稳定有积极作用； 其二，大型互联网公司在AI领域出现突破，形成自身的人工智能应用 ...

Group 1 - The core viewpoint of the news is that the Hang Seng Technology Index experienced significant volatility, with over 5.9 billion yuan flowing into it before the Spring Festival, despite a net outflow of 19.5 billion yuan from the A-share market on the last trading day before the holiday [1][2] - The Hang Seng Technology Index saw a net inflow of over 5.9 billion yuan in the last five trading days leading up to February 13, while the overall stock ETF market faced a net outflow of 194.75 billion yuan during the same period [2] - During the Spring Festival holiday, the Hang Seng Technology Index initially fell but later rose, achieving a 0.47% increase, followed by a significant rise of 3.34% on the last trading day before the holiday [2][5] Group 2 - On February 13, the top-performing ETFs included the China Concept Internet ETF from E Fund, which had a net inflow of 9.41 billion yuan, and the Hang Seng Technology ETF from E Fund, which saw a net inflow of 3.63 billion yuan [4][5] - The wide-based ETFs experienced a net outflow of 258.07 billion yuan, with the China A500 Index ETF leading the outflows at 66.13 billion yuan [6][8] - Despite the short-term net outflows from some broad-based indices, there is optimism regarding the A-share market's future performance, with expectations of a rebound in February [9]

1. Report Industry Investment Ratings No relevant content provided. 2. Core Views - During the Spring Festival, international oil prices continued to rise, with Brent and WTI crude oil reaching new highs since August 2025. Geopolitical risks, especially the tense situation between the US and Iran, are the main drivers of the oil price increase. The next two weeks will be a critical window for the situation, and geopolitical factors will continue to dominate the oil market [1]. - Precious metals showed strong performance during the Spring Festival. With the US - Iran negotiation making no substantial progress and the possibility of US strikes on Iran, the strength of precious metals may continue in the short - term [2]. - For most commodities, the market is affected by various factors such as geopolitical risks, supply - demand relationships, and seasonal patterns. Some commodities are expected to have price fluctuations, while others are likely to maintain a range - bound trend [3][4][5]. 3. Summary by Commodity Categories Energy Commodities - **Crude Oil**: During the Spring Festival, international oil prices rose significantly. Geopolitical risks, especially the tense US - Iran situation, are the main factors. The next two weeks are crucial for the situation, and oil prices will be dominated by geopolitical factors [1]. - **Fuel Oil & Low - sulfur Fuel Oil**: Due to the sharp rise in geopolitical risks between the US and Iran during the festival, oil prices soared. Fuel oil is expected to follow the upward trend. High - sulfur fuel oil is strongly supported by geopolitical factors, while low - sulfur fuel oil is relatively weak and mainly follows the trend of crude oil [21]. - **Asphalt**: International oil prices strengthened during the holiday, and asphalt is expected to start a catch - up rise on the first trading day after the festival. The asphalt market has a pattern of weak supply and demand, and its price follows the trend of crude oil [22]. Metal Commodities - **Copper**: LME copper prices were basically the same as before the holiday. During the domestic holiday, investment and physical demand were weak, and copper prices fluctuated. Copper inventories increased, and the copper market may strengthen the positive market structure. There is a risk that the unilateral copper price will adjust to the MA60 moving average to attract buyers [3]. - **Aluminum**: LME aluminum had limited fluctuations and a slight increase during the Spring Festival. After the festival, Shanghai aluminum is expected to have high - level oscillations. Attention should be paid to the inventory accumulation, demand recovery, and the impact of the US - Iran situation on the supply side [4]. - **Zinc**: LME zinc had high - level oscillations during the festival, with limited guidance for Shanghai zinc. After the festival, Shanghai zinc has weak rebound momentum due to short - term oversupply, but strong cost support. It is expected to oscillate between 24,000 - 25,000 yuan/ton. In the long - term, the oversupply situation remains, and the recovery of TC can be regarded as an opportunity for short - selling at high levels [7]. - **Lead**: The decline of LME lead slowed down near the cost line. After the festival, domestic lead prices are at a low level. Downstream purchases may increase, and recycled lead production has decreased. However, due to the opening of the import window, demand lacks an increase expectation. Shanghai lead is expected to have low - level oscillations between 16,500 - 17,500 yuan/ton [8]. - **Nickel & Stainless Steel**: Shanghai nickel is expected to open higher and then oscillate on the first trading day. During the holiday, the external market was generally strong, and factors such as the US tariff policy and economic data affected the market [9]. - **Tin**: LME tin had a slight increase compared to before the holiday and basically oscillated. The internal and external tin prices are supported by the MA60 moving average. LME tin inventories continued to increase slightly during the festival, and the spot discount narrowed. Tin prices are expected to continue to oscillate, and attention should be paid to the resumption of supply in the main production areas [10]. - **Carbonate Lithium**: Carbonate lithium still has optimistic sentiment in the short - term and is expected to have a strong - biased oscillation. The external market was strong during the holiday, and factors such as the US tariff policy and economic data are favorable [11]. - **Industrial Silicon**: Before the holiday, industrial silicon rebounded slightly after breaking through the previous low. After the holiday, it is expected to continue to oscillate. The supply side may see the resumption of production of large factories in Xinjiang, while the downstream demand is weak, and the social inventory is at a high level [12]. - **Polysilicon**: During the Spring Festival, spot trading was stagnant. Before the holiday, polysilicon futures had a slight increase and narrowed fluctuations. Although there is cost support, the market is expected to maintain an oscillating trend due to factors such as production reduction and inventory accumulation [13]. Ferrous Metals - **Steel (Thread & Hot - rolled Coil)**: During the Spring Festival, the external market generally rose, while the domestic spot market was on holiday. The demand for steel decreased, and the inventory accumulated. Due to factors such as poor steel mill profits and weak downstream demand, the iron - water output remained at a relatively low level. With the improvement of the financial market sentiment, the steel price has a certain rebound momentum after the festival [14]. - **Iron Ore**: During the holiday, overseas iron ore swaps weakened. The supply is relatively strong, and the market is worried about oversupply. Although the demand is expected to improve marginally, the supply pressure is greater, and the price is still under pressure [15]. - **Coke & Coking Coal**: During the holiday, the increase in oil prices may have an indirect impact on the black - series commodities. The inventory of coke increased slightly, and the purchasing willingness of traders was average. The carbon element supply is abundant, and the downstream demand is in the off - season. The prices of coke and coking coal are expected to oscillate in a range [16][17]. - **Manganese Silicon**: The increase in oil prices during the holiday may have an indirect impact. The spot price of manganese ore increased slightly, and the downward space of the disk is relatively small. The inventory of manganese ore in ports may start to increase slowly, and the demand side is at a seasonal low level. The price is affected by oversupply and policy expectations [18]. - **Silicon Ferrosilicon**: The increase in oil prices during the holiday may have an indirect impact. Some production areas have a decrease in power costs, and the demand side is at a low level. The export demand is stable, and the supply changes little. The price is affected by oversupply and policy expectations [19]. Chemical Commodities - **Urea**: During the Spring Festival, the supply of urea remained at a high level, and production enterprises are expected to accumulate inventory seasonally. With the increase in temperature, the demand for agricultural fertilizer preparation is expected to start, and the production enterprises are expected to reduce inventory after the festival. The short - term market is likely to oscillate and rebound [23]. - **Methanol**: The overseas methanol plant operating rate remains low, and the import volume is expected to decrease after the Spring Festival. The coastal MTO plant operating rate is low, and attention should be paid to the profit repair and restart expectations after the festival. The traditional downstream will resume work one after another, and the inventory in the inland and ports is expected to decrease [24]. - **Pure Benzene**: The instability of the US - Iran situation provides support for the cost of pure benzene. The supply during the Spring Festival is relatively high, and the inventory in the East China port is expected to remain at a high level. The downstream demand is expected to improve, and the port inventory may decrease slowly [25]. - **Styrene**: The increase in international oil prices during the holiday boosted the cost of styrene, and it may open higher. However, the supply is expected to increase significantly after the festival, while the downstream demand recovery needs time, and the fundamental contradiction is intensified [26]. - **Polypropylene & Plastic**: The increase in international oil prices during the holiday may boost the opening price after the festival. However, due to the inventory accumulation of polyolefin petrochemical enterprises during the Spring Festival and the slow recovery of downstream production enterprises, the fundamental contradiction is intensified [27]. - **PVC & Caustic Soda**: The PVC industry is in the seasonal inventory accumulation stage. The cost support is strengthened, and the demand for export is strong. The price is expected to rise. The profit of caustic soda has declined significantly, and the cost support is strengthened. The supply may decrease, and the price is expected to operate near the cost [28]. - **PX & PTA**: The strong oil price provides cost support. PX has new capacity in the second half of the year, while PTA has none. In the first half of the year, it is advisable to take a long position. Based on the PX maintenance and polyester production increase expectations in the second quarter, opportunities for long - term PX processing spreads and positive spreads after the decline of the month - spread can be considered [29]. - **Ethylene Glycol**: Ethylene glycol is under long - term pressure due to new capacity, but the supply is expected to shrink, and the downward space is limited. In the second quarter, the supply - demand situation may improve due to centralized maintenance and increased demand [30]. - **Short - fiber & Bottle - grade Chips**: Before the holiday, the production of short - fiber and bottle - grade chips decreased, and the inventory was at a low level. After the holiday, the production is expected to increase. Attention should be paid to the terminal production resumption and inventory preparation rhythm [31]. Agricultural Commodities - **Soybean, Soybean Meal & Rapeseed Meal**: During the Spring Festival, US soybeans continued to be strong. The export and crushing data were good, which boosted the price. The supply - demand balance sheet for the 26/27 US soybean season shows a tightening supply - demand structure [35][37]. - **Soybean Oil, Palm Oil & Rapeseed Oil**: During the Spring Festival, US soybean oil and Malaysian palm oil continued to be strong. The increase in the price of US RIN has a strong driving effect on US soybean oil. The supply - demand balance sheet for the 26/27 US soybean season shows a tightening structure. The short - term upward movement of palm oil has resistance. The export of Canadian rapeseed has improved, and attention should be paid to the policy orientation [36]. - **Corn**: During the Spring Festival, the US is expected to plant less corn in 2026. The US corn futures price oscillated during the holiday. In China, some enterprises in the Northeast started purchasing after the Spring Festival. The trading volume of Dalian corn futures may increase, and attention should be paid to risks [38]. - **Pigs**: After the Spring Festival, the average price of live pigs decreased compared to before the festival. The supply in the spot market is sufficient, and the futures price is expected to continue to weaken. Attention should be paid to the implementation of the pig production capacity reduction logic in the medium - term [39]. - **Eggs**: After the Spring Festival, the egg price decreased slightly. Considering the expected decline in supply in spring, there is a possibility of the futures price continuing to strengthen. It is recommended to go long on the near - month contract at a low price [40]. - **Cotton**: During the Spring Festival, US cotton was strong. The global supply in the 25/26 season is relatively loose, but there is an expectation of supply contraction in the 26/27 season. The domestic cotton market has a good sales situation, and the medium - term Zhengzhou cotton price may be strong [41]. - **Sugar**: During the holiday, US sugar oscillated. In the international market, India's sugar production increased, while Thailand's production was lower than expected. In the domestic market, the market focus is on the expected difference in production. Although the production in Guangxi is currently slow, there is a strong expectation of production increase in the 25/26 season [42]. - **Apples**: The futures price oscillated. The cold - storage trading volume decreased, and the market focus is on the demand side. The high purchase price and the strong reluctance to sell of traders and fruit farmers may affect the inventory reduction speed [43]. - **Wood**: The futures price is at a low level. The supply is expected to decrease in the short - term, and the demand has declined. The low inventory provides certain support, and it is advisable to wait and see for the time being [44]. - **Paper Pulp**: The domestic paper pulp port inventory is still at a high level. The overseas quotation is strong, providing cost support, but the demand is average. The downstream paper mills are cautious about high - price raw material inventory, and attention should be paid to the demand performance after the festival [45]. Financial Products - **Stock Index**: Before the long holiday, A - share major indexes fell by more than 1%, and stock index futures were all at a discount. During the Spring Festival, the Hong Kong stock market was strong, while the overseas stock markets fell. There are uncertainties in trade policies and geopolitical situations. After the festival, the market may maintain a strong - biased oscillation, and attention should be paid to the performance of the technology - growth and cyclical sectors [46]. - **Treasury Bonds**: On February 13, 2026, the treasury bond futures showed a differentiated trend. The long - term contracts are over - priced, and the central bank's bond - buying has not ended, with a strong willingness to maintain the capital market. The TL06 contract has a certain safety margin for long - position trading, and it is appropriate to participate in the unilateral trading of TL or flatten the yield curve [47].
