S&P 500 Posts Fifth Straight Losing Week as Dow Enters Correction, Brent Tops $110, Meta Crashes on Addiction Verdicts, PCE Inflation Runs Hot, and Rate Hike Odds Cross 50%

A week that opened with the most powerful relief rally in a month ended with two major indexes in correction territory and the Federal Reserve’s preferred inflation gauge running hotter than anyone wanted. The contrast between Monday’s euphoria and Friday’s despair captures the impossible crosscurrents that define this market: geopolitical risk that can reverse overnight, an oil price that acts as both a shock absorber and a wrecking ball, and an inflation picture that worsens with every data release.

Monday’s 631-point Dow surge — triggered by Trump’s “productive conversations” with Iran post and a 10% crash in oil prices — was the week’s high-water mark. By Tuesday, Iran had fired missiles at Tel Aviv and Saudi Arabia was edging toward entering the fight. By Wednesday, a brief ceasefire hope flickered as Iran offered Hormuz passage to “non-hostile” ships, sending gold surging 3% and yields lower. Thursday shattered that optimism: Brent surged to $108, Meta crashed 8% on landmark addiction verdicts, and the Nasdaq entered correction territory. Friday was the coup de grâce — a hotter-than-expected PCE print, the Dow entering correction, Brent topping $110, and rate hike odds crossing 50% for the first time.

When the dust settled, the S&P 500 had fallen roughly 2.5% for the week to close at 6,342 — its fifth consecutive weekly decline, matching the longest losing streak since the 2022 bear market. The Dow shed about 1.0% to 45,137, and the Nasdaq dropped roughly 3.0% to 21,104. Every gain from Monday’s rally and then some was surrendered by Friday’s close.

Weekly Scoreboard

The Week’s Narrative

Monday: The Relief Rally That Wasn’t

The week began with what appeared to be a game-changing moment. At 7:05 AM ET on Monday, President Trump posted on Truth Social that “productive conversations” with Iran were underway and announced he was postponing planned military strikes for five days. The market response was immediate and powerful: the Dow surged 631 points (+1.38%) to 46,208.47, the S&P 500 gained 1.15%, and the Nasdaq rose 1.38%. Oil prices crashed — WTI plunged 10.28% to $88.13 and Brent fell 10.92% to $99.94, dropping below $100 for the first time since the crisis began. All 11 S&P 500 sectors advanced. Gold dropped 5.5% to $4,233.54 as the safe-haven unwind accelerated.

But beneath the euphoria, suspicious volume spikes in S&P 500 e-Mini futures and WTI contracts 15 minutes before Trump’s post drew regulatory scrutiny. And Iran itself denied any direct talks, a detail the market chose to overlook in the moment but would pay for later.

Tuesday: The Rebound That Wasn’t

Whatever hope Monday generated was cut short overnight. Iran fired missiles at Tel Aviv, drones struck Kuwait and Saudi Arabia, and the Wall Street Journal reported Saudi Arabia and the UAE were “edging toward entering the fight.” Oil rebounded sharply with WTI surging 4.14% to $91.78 and Brent gaining 3.30% to $99.09 — erasing more than a third of Monday’s crash in a single session. The S&P 500 dipped just 0.32% as Monday’s rally mostly held, but the bond market sounded a warning: a weak $69 billion 2-year Treasury auction — the lowest bid-to-cover ratio since May 2024 — sent the 2-year yield surging 9 basis points to 3.925%. The private credit crisis deepened as Apollo capped redemptions at 5% after receiving 11.2% withdrawal requests.

Wednesday: A Flickering Ceasefire Hope

Midweek brought the week’s only genuine optimism. Iran offered passage through the Strait of Hormuz to “non-hostile” vessels — the first tangible concession since the blockade began nearly four weeks ago. Brent fell 2.17% to $102.22 and WTI dropped 2.2% to $90.32. Gold surged 3% to $4,552 as Treasury yields tumbled — the 10-year fell 7 basis points to 4.322%. The S&P 500 gained 0.55% and small caps outperformed for a third straight day. Morgan Stanley warned that private credit defaults could surge to 8%, and the $70 billion 5-year Treasury auction disappointed — the second weak sale of the week.

Thursday: Three Simultaneous Shocks

Thursday was a catastrophe. Three simultaneous developments hammered the market: Brent crude surged 5.66% to $108.01 after Iran proposed transit fees for all vessels passing through the Strait of Hormuz — a de facto monetization of the blockade. Meta crashed 7.96% after an L.A. jury found the company liable in two landmark child safety and addiction cases, awarding $2.2 billion in combined damages. And the OECD forecast 4.2% U.S. inflation for 2026, nearly double the Fed’s own 2.7% projection. The Dow fell 469 points, the S&P 500 dropped 1.74%, and the Nasdaq entered official correction territory at more than 10% below its October high. Google’s TurboQuant AI chip technology continued to crush memory semiconductor stocks, with Micron down 22% in six trading days.

Friday: The PCE Hammer Falls

Friday delivered the week’s final blow. The February PCE inflation report — the Fed’s preferred gauge — came in at 0.4% month-over-month, above the 0.3% consensus. Core PCE rose 0.3% MoM and 2.8% year-over-year, moving in the wrong direction. Rate hike odds crossed 50% for the first time per the CME FedWatch tool. The Dow entered correction territory. Brent crude topped $110 for the first time since the war began. The S&P 500 fell 1.69% and the Dow shed 1.73%. Every Magnificent Seven stock declined, with Meta losing another 3.99% and Amazon breaking below $200 for the first time since November. Michigan consumer sentiment plunged to 57.0, with year-ahead inflation expectations surging to 5.0% — the highest since the post-pandemic inflation shock.

Sector Scorecard

Energy was once again the only sector to post a meaningful gain, with XLE rising roughly 2.1% as Brent’s move from $108 to $110 lifted the entire complex. ConocoPhillips, Marathon Petroleum, and Valero Energy all hit fresh 52-week highs on Friday. Technology was the worst performer for the second consecutive week, dragged down by the TurboQuant memory chip demand fears and Meta’s historic legal setback. The 30-percentage-point divergence between energy and technology since the war began is the widest sector gap since the 2008 oil shock.

Movers of the Week

Economic Data Roundup

The economic data told a bifurcated story. The S&P Global Manufacturing PMI rose to 52.4 from 51.6, marking an eighth consecutive month of factory expansion, with new orders posting their largest gain since October. But input costs surged on war-driven energy prices, pushing selling price inflation to its highest since August 2022. The labor market remained stable, with initial claims at 210,000 and continuing claims falling to their lowest since May 2024 at 1.82 million.

The Friday data dump was the week’s most consequential. The PCE report showed headline inflation at 0.4% month-over-month — above consensus and the hottest monthly reading since May 2025. Crucially, this data captured only the very beginning of the oil price spike, as the war started on February 28. March’s PCE, due in late April, will reflect the full brunt of the energy shock and is expected to be significantly worse. Consumer sentiment collapsed to 57.0 from 64.7 in February, with year-ahead inflation expectations surging to 5.0% — a level that risks unanchoring long-term expectations and forcing the Fed’s hand.

Fed Watch & Rates

The monetary policy landscape shifted decisively this week. Rate hike probability crossed 50% for the first time on Friday, according to the CME FedWatch tool — a watershed moment. As recently as January, markets were pricing in three rate cuts for 2026. Now the debate is not about when the Fed will ease, but whether it will need to tighten.

Treasury yields surged across the curve. The 10-year climbed to 4.46% — its highest since July 2025 — gaining roughly 7 basis points on the week. The 2-year yield pushed past 4.0% for the first time in months, rising approximately 11 basis points. The 30-year reached its strongest level in months. Three Treasury auctions during the week delivered mixed-to-weak results, with Tuesday’s 2-year and Wednesday’s 5-year both disappointing.

Fed Vice Chair Philip Jefferson said current policy is “well positioned” despite inflation risks, but the market heard no urgency to intervene. The trajectory is clear: if March PCE shows another acceleration (and it almost certainly will given the oil price dynamics), the Fed will face its most difficult policy choice since the 2022 tightening cycle began.

Geopolitical & Macro Developments

The Iran conflict defined the week’s price action, swinging from de-escalation hopes on Monday to renewed escalation by Thursday. The key developments, in sequence:

• Monday: Trump posted “productive conversations” and postponed strikes. Oil crashed 10%. Iran denied direct talks. Suspicious futures volume noted pre-post.
• Tuesday: Iran fired missiles at Tel Aviv and drones at Kuwait and Saudi Arabia. Saudi Arabia and the UAE reportedly “edging toward entering the fight.” Oil rebounded 4%.
• Wednesday: Iran offered Hormuz passage to “non-hostile” vessels — first tangible concession. U.S. sent 15-point peace plan through Pakistani intermediaries. Iran rejected it but submitted a five-point counterproposal. Brent fell 2% below $103.
• Thursday: Iran proposed transit fees for all Hormuz traffic — a de facto monetization of the blockade. U.S. deployed 3,000 troops from 82nd Airborne. Brent surged to $108. OECD forecast 4.2% U.S. inflation. G7 foreign ministers met without resolution.
• Friday: Brent topped $110. Trump extended energy infrastructure strike deadline to April 6 — a 10-day reprieve, though Tehran denied requesting it. Rubio told G7 that hostilities could persist 2–4 more weeks. Average U.S. gasoline at $3.98/gallon; diesel above $5 in multiple states.

Beyond the Iran conflict, the week brought several significant macro developments. A partial U.S. government shutdown continued as House leaders rejected the Senate’s DHS funding compromise, though TSA employees were expected to start receiving pay as early as Monday under executive order. Google’s TurboQuant AI algorithm — which can run large language models using roughly six times less memory — sent memory chipmaker stocks into a multi-day slide, raising questions about the sustainability of the AI memory buildout that has driven billions in capital expenditure. Private credit stress continued to mount: Apollo, Ares, Blackstone, Blue Owl, Morgan Stanley, and Cliffwater have all restricted or disclosed elevated redemption activity. Bloomberg reported $5 billion in private credit assets are now trapped behind withdrawal restrictions.

Corporate Highlights

• Meta $2.2B addiction verdict: An L.A. jury found Meta liable in two landmark child safety cases, awarding $2.2 billion in combined damages. The stock lost 12% in two days, erasing more than $70 billion in market capitalization. Bernstein cautioned that “the legal risk is now structural, not episodic” as thousands of similar lawsuits await trial.
• Google TurboQuant: Alphabet unveiled an AI algorithm that runs LLMs on six times less memory, sending Samsung, SK Hynix, and Micron into a multi-day slide. The Jevons paradox may ultimately offset the impact, but near-term memory chip demand forecasts are being rapidly revised lower.
• SpaceX IPO: Elon Musk is reportedly considering allocating up to 30% of SpaceX’s upcoming IPO to retail investors at a reported $1.75 trillion valuation. Anthropic is also eyeing a $60 billion+ IPO.
• Merck-Terns acquisition: Merck acquired Terns Pharmaceuticals for $6.7 billion in oncology.
• Brown-Forman / Pernod Ricard: Brown-Forman surged 14% on a reported $30 billion Pernod Ricard takeover bid.
• Meta $10B data center: Despite the stock’s collapse, Meta announced it is increasing spending on an El Paso data center from $1.5 billion to $10 billion, doubling down on AI infrastructure.
• David Sacks exits: The White House crypto czar departed with key legislation unresolved. Bitcoin fell below $69,000.
• NYSE/Securitize tokenization: The New York Stock Exchange teamed up with Securitize as traditional finance firms invest in blockchain-based tokenization of real-world assets.
• Schwab teen accounts: Charles Schwab launched joint brokerage accounts for teens aged 13–17, with fractional S&P 500 shares as an educational incentive.

Week Ahead Preview: March 30 – April 3

The week ahead is loaded with tier-one economic data. ISM Manufacturing on Wednesday will provide the first comprehensive read on whether the oil shock is damaging factory activity. But the main event is Friday’s March jobs report — nonfarm payrolls and the unemployment rate will be interpreted through the lens of whether the economy can withstand the energy shock without tipping into recession. Nike’s results on Tuesday will test consumer spending resilience at the margin.

The April 2 reciprocal tariffs — widely discussed as a secondary risk — officially take effect on Thursday, adding another layer of uncertainty for multinational companies already reeling from the energy shock. And the Iran deadline of April 6 looms just beyond the trading week, giving the market a concrete date around which to price geopolitical risk.

The AlphaEdge Take

Five consecutive weeks of losses. Two major indexes in correction. The Fed’s preferred inflation gauge accelerating. Rate hike odds above 50%. Oil at $110 and climbing. This is the most hostile operating environment for equity investors since the 2022 bear market, and the roadmap for relief remains unclear.

Start with what changed this week. Monday’s relief rally was the last gasp of the “TACO trade” — the notion that Trump Always Chickens Out and any escalation will be followed by a face-saving retreat. The market bought that narrative one more time on Monday, pushing the Dow up 631 points. By Friday, that entire gain and more had evaporated. The market has now conclusively priced out the possibility of a quick resolution. Rubio’s 2–4 week timeline suggests the administration itself sees an extended conflict. Oil at $110 is no longer a spike — it is the new baseline.

The rate hike probability crossing 50% is the week’s most significant structural development. For the past three years, the central assumption underpinning equity valuations has been that the Fed would provide monetary easing. That assumption is now dead. If March PCE accelerates further — and with Brent at $110, it almost certainly will — the Fed will face impossible choices. Hiking rates during a potential recession would repeat the policy error of 1980. Holding steady while inflation accelerates would risk credibility. Neither path is good for stocks trading at 19 times forward earnings.

Meta’s 12% two-day decline deserves more than a headline. This is not a revenue miss or a competitive setback. It is a structural reassessment of legal risk for the entire social media sector. If platforms can be held liable for the addictive design of their products, the cost of doing business permanently increases across the industry. Meta’s simultaneous $10 billion El Paso data center expansion suggests the company itself views AI — not social media — as its future. The market is pricing that transition risk in real time.

Amazon’s break below $200 is a proxy for the American consumer. With gasoline approaching $4 per gallon, diesel above $5, and inflation expectations at 5%, discretionary spending is the first casualty. Amazon is the single largest barometer of that spending. Its decline is not company-specific — it is macro-economic.

We see three scenarios for the coming weeks. Our base case (45% probability): the market grinds lower toward the 6,100–6,200 range on the S&P 500 as each new data release confirms the stagflationary trajectory. Oil stays above $105, the April 6 deadline passes without a breakthrough, and investors slowly reduce exposure. The second scenario (20%): a diplomatic breakthrough or ceasefire sends oil back to $90–95 and triggers a 4–6% relief rally. Possible, but nothing this week suggests either side is ready to stand down. The third scenario (35%): further escalation pushes Brent to $120–130, the April 6 deadline triggers U.S. strikes on Iranian energy infrastructure, and equities suffer a 3–5% gap down. This scenario has grown more probable with each passing week.

Our posture remains cautious. Cash is a valid position at 4.46% on the 10-year. Energy remains the only sector with positive momentum, but a single diplomatic headline could collapse the entire trade overnight. Stay hedged, size positions for volatility, and do not try to call the bottom. The VIX above 30 confirms that even the options market is deeply uncertain. The next clear signal will come from one of three places: a credible ceasefire, the March jobs report on April 3, or the April 6 Iran deadline. Until then, the trend remains firmly down.
