Core Viewpoint - The recent reduction in holdings by prominent investors Warren Buffett and Duan Yongping has raised concerns among ordinary investors about potential market shifts, but their actions are more about strategic portfolio optimization rather than panic selling [1][4]. Group 1: Actions of Warren Buffett - Buffett's Berkshire Hathaway reduced its stake in Apple by 10.29 million shares, a decrease of 4.32%, and significantly cut its Amazon holdings by 77.24%, while completely liquidating its position in Google [3]. - Despite the reductions, Apple remains the largest holding for Berkshire, valued at over $61.9 billion, indicating a strategic reassessment rather than a bearish outlook on the market [5][7]. Group 2: Actions of Duan Yongping - Duan Yongping also reduced his Apple holdings by 7.09%, aligning with Buffett's strategy, while simultaneously increasing his investment in Nvidia by 1110.62% and entering several AI-related companies, reflecting a shift towards sectors with perceived higher value [3][5]. - This adjustment is characterized as a repositioning of assets rather than a complete exit from the market [5][7]. Group 3: Investment Philosophy - Both investors are not attempting to predict market fluctuations but are instead focusing on maintaining their investment within their areas of expertise, which exemplifies true value investing [8]. - The actions of these investors serve as a reminder that investment should not be a follow-the-leader game, emphasizing the importance of a steady and informed approach to investing [11].

据报道，特朗普在社交平台 Truth Social 上发文宣布，这一调整"立即生效"，意味着原本计划实施的 10%全球进口关税将被15%的最高税率所取代。他同时表示，政府将在接下来"短短几个月内"推动新 的、且"符合法律要求"的关税方案，意在通过更稳固的法律路径，重建此前被推翻的关税壁垒。 特朗普此举被认为是对最高法院判决的直接回应。此前，最高法院裁定，他推出的那套范围广泛的"对 等关税"方案属非法实施，给苹果等企业带来的数十亿美元额外成本因此被叫停。在新一轮操作中，特 朗普试图通过《贸易法》第122条这一相对更具合法基础的渠道，实现与旧关税方案相近的经济效果， 同时提高其在司法层面被推翻的难度。他在发文中声称，提高税率是基于对最高法院这一"荒谬、拙劣 且极度反美"的裁决进行"全面、细致且完整审查"后的结果。 不过，目前尚不清楚15%的新税率是否会沿用此前10%方案原定的生效时间。按照先前安排，10%的全 球进口关税将于下周二凌晨0点01分（美东时间）正式开始实施，但在最新表态发出后，15%版本究竟 会否按同一时间表启动，官方尚未给予明确说明。 美国总统特朗普此前依据《贸易法》第122条，在其"对等关税"被最 ...

近期，有消息显示苹果筹备已久的新版Siri升级计划再次遭遇技术挫折，原定推出的多项AI功能将拆分至后续系统版本发布。这已是该升级计划自宣布 以来的第二次重大延期，核心问题集中在响应稳定性与准确性上，甚至出现错误调用外部技术的漏洞。对关注科技领域的投资者来说，这类新闻一 出，相关标的的价格波动往往让人难以形成稳定判断：有时利好消息传出后标的价格回调，有时利空落地后标的价格反而反弹，表面现象充满不确定 性。但从量化大数据的视角看，市场波动的核心从来不是新闻本身，而是背后资金的真实交易行为。普通人依赖直觉与经验判断，很容易被表面现象 误导，而量化大数据能帮我们穿透表象，看清真实的资金参与状态。 一、市场波动的核心逻辑 多数人认为，市场价格波动由每日各类消息直接驱动，但实际运行中，消息往往滞后于行情变化。海外市场通常是已知信息直接反映在价格上，而我 们的市场更倾向于提前布局、提前交易，这就导致"买传闻，卖新闻"的现象频繁出现。但即便理解这一规律，依然会面临困惑：相同类型的消息，不 同标的的价格反应截然不同，有的快速修复，有的持续回调。 这背后的本质，是不同标的背后的机构资金选择存在差异。机构资金的交易行为与普通投资者 ...

Group 1 - The core point of the article is that the recent US Supreme Court ruling on the $175 billion tariff refund has significant implications for both China and the A-share market, despite the refund being an internal US matter [2][6][28] - The $175 billion in tariffs was primarily collected from imports, including a 10% tariff on Chinese goods, and is now being refunded to US importers [8][10] - The refund will indirectly benefit Chinese companies as US importers, who have been financially strained by tariffs, will use the refunded money to pay off debts to Chinese suppliers and resume orders [12][14][28] Group 2 - The immediate impact on the A-share market is expected to be positive, with a potential "opening red" for A-shares as market sentiment improves following the ruling [40][46] - The ruling is seen as a signal that the previous high tariffs on Chinese goods may not be a permanent state, which could lead to a more favorable environment for Chinese exports [20][48] - Structural opportunities in the A-share market are identified, focusing on five main lines: export-oriented sectors, domestic substitution, strategic resources, domestic consumption, and new energy [51][62][88] Group 3 - Export-oriented sectors, particularly those with high exposure to the US market, are expected to benefit directly from the tariff refunds, with companies like Midea Group and Haier expected to see improved performance [52][72][73] - Domestic substitution and self-sufficiency in sectors like semiconductors and military equipment are highlighted as long-term strategic focuses, with companies like SMIC and AVIC Shenyang Aircraft being key players [53][78][86] - Strategic resources such as rare earths and gold are also expected to see price support due to ongoing global supply chain disruptions, benefiting companies like Northern Rare Earth and Shandong Gold [56][87]

来源：环球网 更值得关注的是，iPhone 18 Pro Max将搭载基于台积电2纳米制程工艺打造的A20 Pro芯片。相较于前 代，2纳米工艺有望带来显著的能效优化。电池容量的小幅增长与芯片功耗的进一步降低相结合，或将 使该机型在日常使用中实现1.5至2天的续航时间。 不过，iPhone 18 Pro Max未必是苹果产品线中电池容量最大的机型。据传，计划于明年秋季同步亮相的 折叠屏iPhone Fold，可能配备高达5500mAh的电池。但考虑到其展开后屏幕尺寸达7.8英寸，实际功耗 仍存在变数，最终续航表现有待实测验证。 分析认为，对于愿意为高端机型支付溢价的用户而言，续航问题或不再成为使用痛点。据悉，折叠屏 iPhone Fold的起售价可能超过2000美元。 ...

周五苹果股价上涨约1%。 这一裁决意味着，苹果可能开始降低生产成本，并保留更多利润空间。 苹果拒绝对此置评。 苹果公司因关税每季度支出约10亿美元，但随着最高法院就关税作出裁决，这一数字可能开始下降。 美国最高法院周五推翻了总统唐纳德·特朗普大规模关税政策中的重要部分，对其核心经济政策构成重 大打击。 自特朗普去年启动相关关税措施以来，苹果已累计支付约33亿美元关税。 苹果公司因关税每季度支出约10亿美元，但随着最高法院就关税作出裁决，这一数字可能开始下降。 高额关税成本主要源于美国对海外生产的产品及零部件征收的进口关税——尤其是来自越南、印度等亚 洲合作伙伴的产品。 今年5月在阐述应对关税的方案时，首席执行官蒂姆·库克表示，苹果面向美国市场的一半iPhone产自印 度，而大多数销往美国的Mac、AirPods和Apple Watch则来自越南。 在财报电话会议上，库克曾强调，苹果在很大程度上自行吸收关税成本，以避免产品价格突然上涨。 最高法院以6比3的裁决认定特朗普单方面实施的关税违法。这意味着，美国政府可能需要向进口商退还 超过1750亿美元的关税款。 一个重大问题是，苹果是否会积极寻求追回已缴纳的关税， ...

过年回家，忙活了一整年的打工人终于可以闲下放松，但对于手里 iPhone 来说，却是一次「年终大考」。 拍摄出片、出游导航、拜年寒暄、聊天拜年、抢红包……手机反而比平时上班更忙了。 爱范儿收集了几个使用 iPhone 的实用小技巧，给大家拜个早年，顺便帮你和手上的 iPhone，过个顺心快乐年。 iPhone 原相机，也有「烟花模式」 现代人的年味，往往最体现在朋友圈那些红红火火的照片中。 但 iPhone 的摄像头颇有自己的想法，想要驯服起来，还得花点心思。 就比如烟花这种瞬时高亮又色彩丰富的场景，国产影像旗舰基本都配备了「烟花模式」，出片干净又绚丽，而 iPhone 成片总是糊作一团。 其实只要一点小技巧，用 iPhone 也能拍好烟花： 切换到视频模式，右上角选择 4K 60/120 帧模式。 可以适当把焦段切换到 2x 或 3x，让构图更加干净。 开启录像，长按取景框开启自动曝光/自动对焦锁定的方框，然后用手指往下拉调低曝光。 烟花绽放时点击白色的快门按钮，拍下照片。 ▲ 图源：小红书@瑞克ColorAddict 这样拍摄的烟花，不仅更加高清，而且烟花高光和黑夜背景的对比度更明显，更突出烟花本体。 除 ...
