Stock Market Today — S&P 500 Clings to Gains, Dow Bleeds 220 Points and Nasdaq Defies the War Premium, GS Stock Drops 3%

Twelve days. That is precisely how long the U.S.-Iran ceasefire lasted before collapsing over the weekend in Islamabad, taking with it the entire rally that had sent the S&P 500 ($SPX) surging 3.6%, the Nasdaq Composite ($COMP) flying 4.7%, and the Dow Jones Industrial Average ($DJIA) gaining 3% in what was collectively the best week for U.S. equities since November. Monday morning stripped every point of that optimism away. Vice President JD Vance left Pakistan without a deal, President Trump immediately announced a naval blockade of the Strait of Hormuz effective 10 a.m. ET, crude oil exploded back above $100 per barrel overnight, and stock index futures opened sharply lower on Sunday evening — Dow futures dropping 517 points or 1.1%, S&P 500 futures shedding 1.1%, and Nasdaq 100 futures losing 1.2%. By the time the cash session opened Monday, some of the damage had been walked back as reports surfaced that Iranian officials were still reviewing a U.S. proposal tied to nuclear enrichment concessions. But the session's dominant theme never changed: the peace dividend is gone, and the war premium is back.

By mid-morning, the S&P 500 ($SPX) sat at 6,822, up roughly 5-7 points or 0.08% — functionally unchanged and having recovered from an opening loss of 0.3%. The Nasdaq Composite ($COMP) held at 22,966, up 63-69 points or 0.28%, driven almost entirely by software and AI infrastructure names that continue to operate as a relatively insulated pocket of the market. The Dow Jones Industrial Average ($DJIA) told a different story entirely, sitting at 47,690, down 220-226 points or 0.47%, weighed down primarily by a Goldman Sachs earnings reaction that alone subtracted roughly 200 points from the index. The Russell 2000 ($RUT) quietly outperformed all three major benchmarks at 2,639, up 8.5 points or 0.32%, a subtle rotation signal into smaller domestic names seeking shelter from the macro cross-currents hitting large-cap industrials and financials.

The CBOE Volatility Index ($VIX) climbed back above the psychologically significant 20 threshold to a session high of 21.58, having closed Friday at 19.23 — its lowest print since before the Iran war began in late February. Context is important here. The VIX had collapsed 18.4% on Wednesday when the ceasefire was announced, fell another 7.4% to 19.49 Thursday, and slipped a further 1.3% to 19.23 Friday. That entire three-session, 38% compression rebuilt in a single overnight session once the Islamabad talks fell apart. The war-era closing peak was 31.05 on March 27, with an intraday high of 31.65 the same day — the market is not yet pricing catastrophic escalation, but the speed of Monday's VIX rebound from 19.23 to 21.58 illustrates exactly how thin the foundation beneath the ceasefire rally actually was.

Oil Roars Back Above $100 — and Some Are Already Pricing $140

West Texas Intermediate crude ($CL=F) hit an overnight peak near $104-$105 per barrel before trimming to $102.13-$102.18 by mid-morning, still up 5.66-5.76% on the session. International Brent crude ($BZ=F) pushed to $100.49-$100.56, up 5.56-5.63%. This is not a technical bounce — it is a direct fundamental repricing of restricted supply risk at one of the world's most operationally irreplaceable maritime chokepoints. At the Sunday night extreme, WTI had jumped as much as 8.54% to $104.82 per barrel and Brent surged as much as 9.1% to near $104 before trimming as markets assessed the precise operational scope of the blockade restrictions.

The U.S. Central Command's clarification that the blockade applies specifically to vessels entering and exiting Iranian ports — while explicitly leaving other traffic transiting the strait unrestricted — removed some of the overnight panic premium. But the structural threat has not changed. The Strait of Hormuz handles roughly 20% of global seaborne oil flows. Any Iranian countermeasure — targeting non-Iranian tankers, deploying fast attack craft against U.S. naval assets, or mining approaches to the strait — could transform this into a supply shock of a magnitude not seen since the 1970s. Onyx Capital Group Managing Director Jorge Montepeque argued on Bloomberg TV that current futures prices fail to fully reflect the real risk, stating plainly that oil "should be $140, $150." That view sits at the extreme end of the range, but it is not analytically indefensible given the scenario tree.

Iran had strategically been running elevated export volumes in anticipation of exactly this kind of escalation — shipping 1.84 million barrels per day in March and 2.15 million bpd in February, roughly 26% above 2025 average levels, with much of that volume pre-positioned in storage outside the strait for Chinese buyers. That stockpile provides Tehran and Beijing a buffer of potentially weeks to months under blockade conditions. The oil market is therefore not staring at an immediate 2-million-barrel-per-day hole in global supply — but it is pricing elevated probability that this situation does not resolve on a short timeline.

Energy equities were among the session's clearest winners. APA Corp ($APA) climbed 2.45% to $39.58. Occidental Petroleum ($OXY) added approximately 3% in premarket trading. CF Industries ($CF), the fertilizer producer with direct natural gas and energy input cost exposure, rose 3.13% to $125.11. The S&P GSCI Commodity Index ($SPGSCI) advanced 2.09% to 719.38, confirming broad commodity repricing across energy and agricultural markets simultaneously. Oil producers with direct Brent exposure remain tactical buys as long as the blockade holds.

Trump escalated the rhetoric further on Monday morning, posting that any Iranian fast attack vessels approaching the blockade perimeter would be "immediately eliminated." He cited the destruction of 158 Iranian naval vessels as evidence of U.S. military resolve. Iran's government called the blockade "an act of piracy" and vowed to target all Persian Gulf port infrastructure if its own energy export hubs face direct attack. The Wall Street Journal reported that Trump is simultaneously weighing a resumption of limited targeted military strikes inside Iran, with officials noting that a full-scale bombing campaign escalation was considered less probable given the risk of broader regional destabilization. Mediators from Pakistan, Egypt, and Turkey are continuing parallel backchannel talks with both parties. UK Prime Minister Keir Starmer explicitly said London is "not supporting" the blockade and will not be dragged into the conflict militarily. French President Macron announced that France and the UK will co-host a multinational conference aimed at restoring freedom of navigation through the strait on a "peaceful" and "strictly defensive" basis, separate from either belligerent.

Iran's stated demands at Islamabad — operational control over the Strait of Hormuz, formal war reparations, and release of frozen sovereign assets — are nowhere near any position Washington has signaled willingness to accept. The nuclear enrichment question was where the U.S. side formally broke off talks. The gap between the two positions is wide on every dimension simultaneously. There is no deal this week, and probably not next week either.

Goldman Sachs Beats on Every Line Except the One That Mattered

Goldman Sachs ($GS) fell to $879.21-$879.81, down $27.99-$28.59 or 3.08%-3.15%, contributing approximately 200 points of downward pressure to the Dow Jones Industrial Average in a single session. The irony is that Goldman's headline numbers were genuinely exceptional. Net earnings rose 19% year-over-year to $5.6 billion. EPS landed at $17.55, comfortably clearing the $16.34-$16.49 consensus by more than $1 per share. Revenue hit $17.23 billion against $16.97 billion expected. The markets division reported $9.3 billion in total revenue, up 8.6% from a year ago. The equity trading desk posted the best quarterly revenue in Goldman's history. Investment banking fees surged 48% year-over-year to $2.84 billion. M&A advisory alone jumped 48% to $1.5 billion, the strongest evidence yet that corporate deal activity is genuinely recovering after years of suppressed volumes. By virtually every conventional measure, Goldman delivered an outstanding quarter.

The single number that dismantled the entire reaction: fixed income, currencies, and commodities intermediation revenue came in at $4.01 billion — down 10%-13% from Q1 2025 and $810-$900 million below the $4.82-$4.92 billion consensus range. The market had built Goldman's Q1 expectations on the premise that war-driven volatility in interest rates, credit spreads, oil-linked derivatives, and currency markets would generate exceptional FICC trading revenue. That thesis was entirely reasonable — a Middle East war affecting inflation expectations, sovereign bond markets, and global currency flows should produce exactly the kind of dislocated pricing that large fixed income desks monetize. The problem was timing. The ceasefire window that covered a meaningful portion of the quarter compressed rate and credit volatility at the exact moment Goldman's FICC desk needed it most. Record equity trading and collapsing fixed income trading in the same quarter captures the essential Goldman story: the bank was positioned for the wrong type of market turbulence. Goldman is a hold at best until management clarifies the FICC trajectory and whether Q1 was a timing anomaly or a structural shift in the business.

The broader bank earnings calendar amplifies the importance of this week's remaining reports. JPMorgan Chase ($JPM), Citigroup ($C), and Wells Fargo ($WFC) report Tuesday. Bank of America ($BAC) and Morgan Stanley ($MS)followWednesday.CollectiveQ1profitsforthesixmajorU.S.banksareforecasttoriseroughly5$BKX) is up just 1% year-to-date after its worst first-quarter performance since the 2023 mini-banking crisis — an index that was supposed to benefit from the Trump deregulation and deal-making revival narrative. Goldman's FICC miss on the opening day of earnings season sets a cautious tone heading into Tuesday's trio of reports.

Revolution Medicines Rewrites Pancreatic Cancer Treatment

The most consequential individual stock move of Monday's session had nothing to do with oil or geopolitics. Revolution Medicines ($RVMD) traded at $130.77, up $34.34 or 35.61%, after touching 71% higher in premarket following a Phase 3 clinical trial result that genuinely deserves the word "landmark." The company's oral daily pill daraxonrasib was tested against pancreatic cancer — statistically one of the most lethal malignancies in oncology, a disease where median survival has barely improved in 30 years despite dozens of failed therapeutic attempts. Patients on daraxonrasib lived a median of 13.2 months — more than double the survival observed in the chemotherapy control arm. The trial met every primary endpoint. CEO Mark Goldsmith described the outcomes as "dramatic" and "practice-changing," and for once that kind of language is justified by the underlying data. Doubling survival in pancreatic cancer is not incremental. It is a category-defining clinical result. RVMD is a buy on any post-gap consolidation. The addressable market across RAS-mutant solid tumors extends well beyond pancreatic cancer, and the Phase 3 data provides a clear and accelerated regulatory pathway.

Oracle Surges 9% While Palantir Fights for Credibility at $133

Oracle ($ORCL) surged 9% Monday, one of the session's cleanest and most sustained moves. Enterprise cloud infrastructure and AI database demand continues to generate the kind of durable revenue acceleration that justifies premium multiple expansion. Oracle has increasingly positioned itself as a critical layer in enterprise AI deployment — not just a legacy database vendor — and Monday's 9% move reflects institutional conviction in that repositioning. Oracle is a buy.

Palantir Technologies ($PLTR) traded at $133.25, up $5.19 or 4.05%, attempting to recover from a brutal prior week that saw the stock fall more than 12%. The catalyst for that selloff was a post from investor Michael Burry on X directly claiming that Anthropic "is eating Palantir's lunch" in enterprise AI — a post he subsequently deleted. The deletion softened the immediate pressure but did nothing to answer the underlying competitive question. Palantir is down nearly 30% year-to-date through Friday's close, a brutal drawdown for a stock that was treated as a primary AI beneficiary entering 2026. Monday's 4.05% rebound looks technically driven — short covering off an oversold setup — rather than fundamentally motivated. The AI competition narrative surrounding Palantir will not disappear without a concrete product or contract response from management. Hold, with significant skepticism.

Amazon Tests $240 — The Most Important Technical Level in Mega-Cap Tech

Amazon ($AMZN) leads the Magnificent Seven recovery off the March 30 lows, pressing into a technically critical resistance zone at $238-$240. That zone has capped every meaningful rally attempt since early 2025, aligning with a downtrend line drawn from the November 2025 high and the January 2026 peak. The stock traded slightly lower Monday — precisely the behavior expected at a resistance test. This is a genuine decision point. If Amazon breaks and holds above $240 with volume confirmation, the technical pathway reopens toward all-time highs in the $255-$260 range. If the level holds as resistance and the stock pulls back, the bull case requires holding the $220-$225 zone, where the 200-day moving average and recent structural support converge. Long-term holders stay positioned. Traders wait for the $240 break before adding.

Taiwan Semiconductor Manufacturing ($TSM) held at $369.84, down a negligible 0.21%, trading near multi-month highs ahead of a Thursday earnings call that functions as one of the most important data points in global technology. Analysts expect Q1 net profit of T$542.6 billion — approximately $17.1 billion — representing a 50% year-over-year surge. Demand for TSMC's 3-nanometre AI chip production technology continues to structurally outstrip current manufacturing capacity. The company's market capitalization sits near $1.6 trillion, approximately double Samsung Electronics. Thursday's call will include second-quarter guidance and an updated full-year outlook that the entire semiconductor and AI infrastructure investment community will treat as a primary read on the durability of global AI capital expenditure. TSMC is a buy ahead of the print.

Goldman Cuts Best Buy, Lifts Williams-Sonoma — Retail Gets Bifurcated

Williams-Sonoma ($WSM) rose 1.66% to $192.28 after Goldman Sachs upgraded the kitchen and home goods retailer to buy, arguing the stock is trading at attractive valuation levels relative to what Goldman described as one of the strongest proprietary brand portfolios in all of U.S. retail. Williams-Sonoma's owned brands — Pottery Barn, West Elm, Williams-Sonoma proper — give it pricing power that commodity retailers simply do not have. In an inflationary environment with elevated input costs, that distinction is material. Buy.

Best Buy ($BBY) dropped 3.35% to $60.28 on a Goldman downgrade to sell. The thesis is surgical: Best Buy likely benefits in Q1 from consumers pulling forward PC purchases ahead of expected price increases, combined with elevated tax refund flows. But as higher memory costs work through the semiconductor supply chain into laptop and desktop pricing, same-store sales face a compressing headwind in Q2 and beyond. Best Buy is fundamentally a hardware distributor with minimal pricing power in a rising-component-cost environment — it passes through cost increases rather than absorbing them, which makes it a poor inflation hedge. Sell.

Fastenal ($FAST) fell more than 4% despite reporting first-quarter EPS of exactly $0.30 and revenue of exactly $2.2 billion — both meeting the FactSet consensus with no deviation. In a market that entered earnings season with elevated expectations for any industrial name with construction and manufacturing channel exposure, meeting estimates precisely reads as a soft result. The underlying business environment for industrial supply distributors is not accelerating fast enough to justify current valuations amid ongoing macro uncertainty. Underweight.

Carnival Sinks 3.65% as the Oil-Cost Math Turns Brutal

Carnival Corp ($CCL) slid 3.65% to $26.96, and the logic is straightforward enough to state simply. Oil at $102 per barrel directly inflates fuel costs for one of the world's largest commercial vessel fleets. Sustained geopolitical conflict in and around the Persian Gulf suppresses consumer confidence in international travel itineraries. Forward booking windows for cruise lines are long enough that uncertainty compounds — a customer making a booking decision today about a cruise six months from now has no visibility into what the Middle East looks like at departure. Carnival is a tactical sell into the current oil spike. The stock is structurally cheap on long-duration metrics, but it has no near-term positive catalyst and two direct operational headwinds simultaneously. Wait for oil to pull back meaningfully before revisiting.
