Abstract

March 31 Market Summary: End of Q1, S&P Down Over 7% as War Takes Its Toll U.S. stocks closed a difficult quarter, with the S&P 500 falling over 7% and moving close to correction territory. The Nasdaq and Dow Jones both entered corrections, a situation not seen since the Fed's aggressive 2022 rate-hike cycle. The market's internal structure was distorted, with energy and defense stocks gaining while tech and consumer stocks plummeted. The tech sector saw a "death cross" and its longest monthly losing streak since 2002. Oil prices remained a dominant story, with WTI crude closing at $102.88, up roughly 80% for the quarter, driven by continued Middle East supply disruptions. Gold fell sharply in March but still posted a positive return for the quarter. Bitcoin fell over 30% in Q1, making it the worst-performing major asset class. The crypto market faced persistent pressure from shifting liquidity expectations as the Fed's next move appeared to shift from potential rate cuts to possible hikes. The quarter's losses were largely concentrated in the 32 trading days following the U.S.-Israel strike on Iran. The market now looks to April 6, a deadline set by former President Trump regarding the Strait of Hormuz, with outcomes ranging from oil above $130 to a prolonged period of uncertainty.

US Stocks: End-of-Quarter Settlement Day, Q1 Bill Presented to Everyone

Tuesday, the calendar turned to March 31, also flipping to the last page of the first quarter of 2026.

As of Monday's (March 30) close, the S&P 500 stood at 6,343, down over 7% for the quarter, more than 9% off its late January all-time high, just a step away from correction territory. The Nasdaq is already in correction, and the Dow officially entered correction last Friday—this is the first time both the Dow and Nasdaq have fallen into correction simultaneously since the Fed's aggressive rate-hike cycle began in 2022. The Russell 2000 small-cap index fared worse, closing at 2,414, with a correction depth exceeding 12%. The S&P recorded five consecutive weekly declines, the longest such streak since 2022.

The end-of-quarter "window dressing" effect should have provided some support, as fund managers tend to rebalance portfolios at quarter-end, selling losers and buying winners to create a favorable-looking portfolio. But in Q1 this year, "winner" is a contentious term: energy and defense stocks rose, at the cost of tech and consumer stocks plummeting. The answer locked in by fund managers as the "best holdings" often turned out to be oil stocks that outperformed the market, not Nvidia or Microsoft.

This distorted internal structure was clear in Monday's session. The Dow rose only 49.5 points (+0.11%), supported by Wells Fargo, JPMorgan, and energy companies; the S&P 500 fell 0.39%, and the Nasdaq dropped 0.73%, with the tech sector again acting as a drag. Micron plunged 9.7% in a single day, a microcosm of the war's slow bleed on chip stocks: Google's computing power algorithms and semiconductor supply chain uncertainties under the Strait of Hormuz blockade have turned the once-beloved AI hardware stocks into nervous wrecks. The tech sector's 50-day moving average has fallen below its 200-day moving average, forming a "death cross," with five consecutive monthly declines—the longest such streak since the dot-com bubble burst in September 2002.

One statement from Monday is worth archiving for history: Fed Chair Powell, speaking at Harvard University, explicitly stated that Fed policy is "in the right place" and inclined to "look through" this supply-side shock. He said: "By the time the tightening effects of monetary policy truly transmit to the economy, this oil price shock will likely be long gone; it would be inappropriate to suppress the economy then." This is a textbook dovish stance—but the market's response was to continue falling, as oil prices kept climbing simultaneously, with WTI standing above $102.88 and Brent above $108.

Powell's "looking through" and oil's "not looking through" are the most unsolvable contradiction in the market at quarter-end.

Today's highlights are both data and earnings: Consumer Confidence Index (March) and JOLTS Job Openings (February) will be released during the session, while Nike will report earnings after the close—the only heavyweight Dow component earnings this quarter and the first end-of-quarter report card for a consumer giant since the war began. Wall Street's consensus estimates: EPS around $0.29, down about 46% year-over-year, revenue around $11.2 billion, roughly flat compared to last year. Against a low base, the impact of the Hormuz blockade on supply chains in Vietnam and India will be a key variable in management's commentary.

Morgan Stanley's call is worth highlighting separately: the bank downgraded global stocks to "neutral" just before quarter-end, simultaneously upgrading US Treasuries and cash to "overweight." The reason: "The uncertainty around the scale and duration of oil supply disruptions makes the outlook for risk assets increasingly asymmetric"—this is a top Wall Street institution using the most restrained language to convey the most pessimistic forecast.

Gold and Oil: Oil Remains High at Quarter-End, Gold Rebounds Against the Trend

Oil: $103, War Premium Has Not Faded

WTI crude closed Monday at $102.88/barrel, with Brent crude around $108 to $109, both hitting new阶段性 highs since the Iran war outbreak. The catalyst came from weekend escalations: Yemen's Houthi rebels launched missiles at Israeli and US military targets, and Iran attacked an oil tanker passing through Kuwaiti waters at night—the latter directly triggered a new surge in futures during Monday's after-hours session.

The war's total bill for oil prices from the data: WTI was around $57 at the start of the year, now up about 80%. This is the biggest market story of the quarter.

A macro perspective worth recording: some economists point out that the current global supply contraction intensity is comparable to the OPEC embargo shock during the 1973 Arab-Israeli War. The IEA has characterized this crisis as "the most severe global energy security challenge ever."

Gold: Seeking Conditions for Another Takeoff in the Cracks of the Oil Inflation Chain

Gold rose about 1.4% on Monday, trading around $4,542 to $4,544, with the lowest point跌破 $4,100 now behind it.

Gold's structural situation remains complex: on one hand, it is indeed pressured by a stronger dollar amid rising inflation expectations; on the other hand, the war itself and persistent central bank accumulation demand have never disappeared. Gold's overall March decline was about 17%, the worst single month since 1983—but that was a pullback after hitting an all-time high of $5,600. Standing at quarter-end, gold still recorded a positive return for the quarter, remaining one of the best-performing major assets this year besides energy stocks.

Cryptocurrency: Bitcoin Stabilizes, But Quarter-End Bill Also Looks Bad

Bitcoin was around $66,727 on Monday, having briefly rebounded to near $67,747 intraday, but the quarterly performance was dismal, down over 30% from the early January high around $97,000, officially becoming the worst-performing mainstream asset class this year.

An unexpected signal emerged at quarter-end: Strategy paused its Bitcoin purchases for the first time this week, breaking a 13-week consecutive buying streak in the most intense week of the war. This may not necessarily be a bearish signal; it could be internal management operations. But against the backdrop of Bernstein recently calling the "bottom in," the timing of this pause is particularly noteworthy.

Bitcoin's situation throughout Q1 has its own internal logical complexity: it initially fell with all risk assets at the war's outbreak, then rebounded in某些 stages, showing some "geopolitical crisis resilience," but under a macro environment where rate expectations shifted towards hikes, it ultimately couldn't escape the gravity of liquidity logic. The global crypto total market cap shrank about 25% in Q1 to around $2.5 trillion, with the Fear & Greed Index hovering around 25 (extreme fear).

The main压制力量 for the crypto market in Q1 wasn't a single crash, but a persistent liquidity tightening expectation—when the Fed's next move changed from "rate cuts" to "possible hikes," all high-risk assets were repriced.

Today's Summary: End of Q1, How History Will Record These 32 Days

March 31, 2026 Q1 close:

US Stocks: S&P 500 down over 7% for the quarter, Dow and Nasdaq in correction, tech sector five consecutive monthly declines, longest since 2002, VIX above 30. Almost all of this quarterly decline occurred within the 32 trading days after the US-Israel joint strike on Iran on February 28.

Oil/Gold: WTI crude rose from around $57 to $102 for the quarter, up about 80%, the most direct冲击波 transmission path of the war to the global economy; gold, after hitting a historical high of $5,600, fell back to around $4,500, still recording a positive return for the quarter, but down about 17% in March alone, the worst single month since 1983.

Cryptocurrency: Bitcoin down over 30% for the quarter, becoming the worst-performing mainstream asset in Q1, but has recovered somewhat from the worst low around $62,800, now stabilizing in the $66,000 to $68,000 range.

The market now only cares about one question: When April 6 comes, will Trump really press the button?

April 6 is Trump's latest deadline; if the Strait of Hormuz remains closed by then, he will face the choice of striking Iranian energy infrastructure or delaying again. Both outcomes have market costs: the former意味着 oil above $130 and real recession risk; the latter意味着 further erosion of Trump's negotiation credibility, and the market will start seriously pricing a "long-term blockade" scenario.

No one knows which path will be chosen. Only that the first quarter has ended, and the cost of those 32 days is written in the K-lines of every asset class.

Apple's Desired On-Device AI Sees a Dark Horse Emerge: The First Cognitive Model is Born, 4B Matches GPT-5.4

A Chinese company, Tomorrow's Journey (Nextie), has introduced what it is calling the industry's first "cognitive model" for edge devices. Named New Journey Alpha, this 4-billion-parameter model reportedly matches the performance of trillion-parameter giants like GPT-5.4 in group intelligence tasks such as debate and collective decision-making. The development follows Andrej Karpathy's vision of stripping vast factual knowledge from large language models to retain only a smaller "cognitive core" capable of reasoning, planning, and knowing its own limits. This approach directly addresses the soaring computational costs and token expenses hindering AI's widespread deployment, as highlighted by incidents like Amazon shutting down an internal AI tool due to prohibitive costs. Trained via reinforcement learning on a corpus of academic papers from 1800-2020 to enhance generalization, the model enables three key advancements: 1) Improved decision quality in multi-agent systems, 2) Drastically reduced compute costs, allowing for cost-effective cloud or on-device (e.g., MacBook) deployment, and 3) The feasibility of "proactive" AI agents that act autonomously without user prompts, unlocking new commercial possibilities beyond today's reactive models. Built by the former Microsoft Xiaoice team—known for creating a 3.6B model that outperformed a 65B Llama model—the company is now focusing on the multi-agent systems sector, a field gaining significant investor interest. The model's economic impact is profound; by achieving high-level performance with minimal parameters, it fundamentally alters the cost structure of AI services, challenging the prevailing model of ever-larger parameter counts.

OpenAI's 'Blueprint for the Future': Making AI Beneficial for Every Person on the Planet

A new transformative technology emerges every few generations. OpenAI draws a parallel with the advent of electricity in the 1920s, which initially brought convenience but ultimately enabled unprecedented progress in medicine, engineering, and living standards by empowering people to create new possibilities. AI is poised to recreate this phenomenon. Its true significance lies not in the technology itself, but in what people can achieve with it—from understanding a medical bill or starting a business to aiding scientific discovery. OpenAI believes AI should be universally accessible, allowing everyone to use it according to their own needs. This future, however, is not guaranteed. While transformative tech can centralize power, OpenAI's philosophy is that AI must serve humanity, augmenting human capabilities and broadly distributing its benefits. The company's first commitment is to build AI for human service, aiming to empower the many rather than concentrate power in a few. Safety, alignment with human intent, and oversight are paramount. OpenAI is optimistic about AI's potential to expand human welfare but remains clear-eyed about risks. The goal is to help people achieve more, not to replace them. Full automation is not the desired future; human judgment, values, and direction will become even more critical. OpenAI outlines three core goals: 1. Build automated AI researchers to accelerate and increasingly automate the research process itself, maintaining close human collaboration. The internal projection is that by March 2028, a significant portion of their research will be conducted by AI systems working alongside human researchers. 2. Accelerate economic development by advancing science, boosting productivity, and fostering growth, while ensuring the fruits are widely shared. 3. Provide a personal AGI for everyone on Earth, allowing individuals to benefit from this transformative technology in their own way. The company is entering its third phase, moving from foundational AGI research (Phase 1) to product deployment and learning from real-world use (Phase 2). The current challenge is making advanced AI abundant, affordable, safe, practical, and usable for all individuals and organizations. OpenAI concludes that a widely distributed power structure leads to a more resilient, adaptable, and free society. A positive AI future should not be controlled by a handful of entities but built, benefited from, and owned by many. If realized correctly, AI can become a cornerstone for enhancing global productivity, creativity, scientific advancement, and economic opportunity, fulfilling the mission to ensure AGI benefits all of humanity.
