Russia’s Ust-Luga port sustained fresh damage from a Ukrainian drone attack, as Kyiv steps up strikes on Russian oil export infrastructure. The Leningrad region came under a fresh Ukrainian drone attack overnight, Governor Alexander Drozdenko said in a Telegram post early Sunday. Air defenses have shot down 31 drones so far, while the emergency services are working to put down a fire at Ust-Luga port, he said. The Leningrad region on the Baltic coast hosts major Russian export hubs and has come under repeated Ukrainian attacks over the past week. Loadings at Ust-Luga have been halted since Wednesday after it sustained significant damage, endangering Russian oil exports. Another port in the region, Primorsk, has also sustained damage. Just before the recent Ukrainian attacks, Primorsk and Ust-Luga handled about 45%, or 1.72 million barrels a day, of Russia’s seaborne crude exports, shipment data seen by Bloomberg show. The damage to both ports threatens to blunt a potential boost to Russian oil export revenues from price increases sparked by the Iran war. The jump had given President Vladimir Putin an opportunity to cover part of a widening budget gap as the economy slows. Read: Ukrainian Attacks Threaten Russia’s Oil Profits From Iran War Both Russia and Ukraine strike each other daily with drones and, at times, missiles as the war enters its fifth year. Ukraine’s attacks are aimed at cutting Russian profits used to sustain the war, often targeting oil, energy and other industrial infrastructure. Russia often hits civilian infrastructure in addition to industrial sites. Overnight, eight people were injured in a Russian drone attack in Ukraine’s Mykolaiv region, according to regional authorities.

美国国土安全部持续的资金缺口于周日进入新的阶段，成为美国历史上持续时间最长的部分政府停摆。 此次国土安全部停摆已进入第44天，打破了此前该部门与其他联邦政府机构自去年10月至11月中旬无资金可用的纪录。而此次停摆中，其他联邦部门与机构均已获得资金支持。 周五，众议院共和党人投票通过一项短期拨款法案，但该法案在参议院毫无通过可能，这让重启国土安全部资金的谈判遭遇重大挫折。而就在数小时前，参议院刚通过一项两党法案，为国土安全部除移民与海关执法局、海关与边境保护局之外的所有部门提供资金。众议院共和党领导层否决了该法案，议长迈克・约翰逊称其“就是个笑话”。 众议院通过的为国土安全部全额拨款的法案，几乎不可能成为法律。自停摆开始以来，参议院已多次尝试推进相同法案，但均以失败告终，始终未能达到推进立法所需的60票门槛。共和党在参议院以53：47占据多数席位，推进立法仍需部分民主党议员支持。民主党则要求在移民执法行动中设置明确的约束条款，才会支持为包含移民与海关执法局在内的国土安全部全额拨款。 责任编辑：陈钰嘉

供给侧的出清，比需求更值得重视 这次，锂电又开始被资金关注了。 3月27日，A股锂电板块盘中涨幅近3%，融捷股份，赣锋锂业、永杉锂业、盛新锂能等十余只个股涨停。 大盘同期下跌，锂电独自走强。这种画面，上一次出现还是2021年。 要知道，2021年不少锂电板块因新能源汽车需求的爆发出现了较大的上涨行情，比如：宁德时代、赣锋锂业等不少锂电企业的股价涨幅超过40%。 这次的逻辑却有所不同。梳理消息面和产业链动态，妙投发现，这次锂电产业链不仅呈现需求增长，还呈现供给收缩的趋势。 市场在大涨，但有一个问题没有被充分讨论。这次锂电产业链供需改善，是一次性的周期反弹，还是趋势性的结构反转？ 一、需求侧信号已经足够清晰 回望过去几年，由于2021至2022年行业内激进扩产，新增产能集中释放，叠加新能源汽车增速开始放缓，锂电产业的供给过剩于2023年左右开启。 到了2025年，在政策的推动下，储能电池的商业模式进一步跑通了，开始超预期爆发。 2025年下半年，锂电板块需求增长的最大驱动力，已经悄然从“车载动力电池”切换到了“储能电池”。 第一转折点，就是2025年发布的“136号文”。 该文件明确，光伏发电不再实行统购统销，全部进入市场化交易。 市场化交易的本质就是随行就市。白天光伏发电多、电网不缺电时，电价极其便宜；到了晚上没有光伏、用电量攀升时，电价飙升。这就导致电网的“峰谷价差”被急剧拉大。 这样一来，储能电池的“低谷充电、高峰放电”的套利作用就显现了。 账算明白了，企业才有动力建，资本才有胆量投，订单才会迎来真正的爆发。 这个转变，才是储能真正爆发的起点，并已经体现在数据上。 据高工产研锂电研究所（GGII）统计，2024年中国锂电池出货量为1175GWh，同比增长32.6%。其中动力、储能电池出货量分别为780GWh、335GWh，同比分别增长23%和64%。 而到了2025年，中国锂电池出货量预计达1875GWh，同比大增53%。其中动力电池出货量1.1TWh，同比增长41%，而储能电池出货量飙升至630GWh，同比增长85%。 相较于2024年，储能电池出货量呈现出明显的加速增长态势。 尤其值得一提的是，2025年第四季度储能锂电池出货环比增长超20%，同比增长超60%。 2026年1月，《关于完善发电侧容量电价机制的通知》（“114号文”）正式出台，再次加强储能爆发的...

多名外交官表示，有关世界贸易组织改革及延长数字下载等电子传输免征关税暂缓令的谈判于周日进入最后一日，目前仍看不到突破迹象。三名外交官透露，各国贸易部长正在喀麦隆举行的世贸组织会议上，试图弥合美国与印度在延长电商关税暂缓令问题上的分歧，该暂缓令将于本月到期。在过去一年经历了关税引发的贸易动荡及中东冲突造成的大规模供应链中断后，此次暂缓令延期被视为检验世贸组织是否仍具现实意义的试金石。三名外交官称，印度方面表示可接受延期两年。但美国贸易代表贾米森 格里尔表示，美方无意对该禁令进行临时延期，只支持永久延期。（新浪财经）

Yes, we stay awake all night, worrying about things that everyone else has already forgotten. But at least we’re making an effort It takes a certain kind of bravery to speak out on behalf of a much-maligned group, so thank you, Mark Travers, PhD. This American psychologist has publicly detailed three reasons overthinkers make great partners. Finally, some justice for those of us whose brains don’t have an off switch, when we usually get such a bad rap (which we then lie awake at night endlessly ruminating on). To us, overthinking isn’t even the correct term – it’s just thinking. Calling it overthinking suggests there are underthinkers, who must be a happy bunch, or perfect-level thinkers, who probably live by the Eleanor Roosevelt/Kung Fu Panda quote: “Yesterday is history, tomorrow is a mystery, but today is a gift – that’s why it is called the present.” An overthinker would hear that and panic, clearly, because were we meant to buy a present too? Is it going to be awkward now? Continue reading...

bgwalker/iStock Unreleased via Getty Images The current macroeconomic landscape is creating significant headwinds for Home Depot's ( HD ) business, which are hard to ignore. When I last wrote about HD in June 2025 , I rated the stock as hold, but I do not believe it is justified anymore. Poor consumer sentiment, a weak housing market, and fears of stagflation driven by the ongoing war in the Middle East are all likely to negatively impact HD's financial performance in the coming quarters. Demand for the firm's products has already showed signs of weakness in the most recent quarter. Declining revenue, contracting margins, declining comparable customer transactions and increasing receivables are all clear signs for me that it is not worth investing in Home Depot's stock right now. Financial Results And The Macro Landscape In the most recent quarter, HD reported revenue decline, margin compression, and EPS decline. There is not much reason for optimism looking at these results. One may say that the revenue decline is driven by the 13-week quarter compared to the 14-week quarter a year ago and in fact comparable sales grew by 0.4%, so the results may not be as bad as they seem. From one side true, because the 14th week in the prior year contributed approximately $2.5 billion to the revenue. Q4 results (Home Depot) On the other side, there are several other metrics that are raising significant concerns about the demand. First, comparable customer transactions declined, demonstrating that the demand is indeed softening. This was partially offset by a growth in comparable average ticket, however. Selected sales data (Home Depot) Further, if we look at the balance sheet, we can see that the company's receivables increased materially compared to the prior year. If accounts receivable increase at a faster pace than revenue, it could be a warning sign that the firm is selling more on credit, potentially pulling demand forward from future periods. Home Depot's receivables incr...
