The Top Line
Stocks finished May at record highs — nine weeks in a row of gains — powered by extraordinary results from artificial intelligence companies, even as inflation remains stubbornly high and a Middle East peace deal is still not finalized. This week, the focus shifts to jobs: Friday's employment report will be the most important data point before the Federal Reserve meets on June 17th to decide what to do with interest rates.
We are operating in a Transitional/Mixed regime characterized by momentum-driven equity expansion coexisting with structurally elevated inflation and unresolved geopolitical risk. The S&P 500 closed May at 7,580.05 — up 5% for the month, marking nine consecutive weeks of gains, the longest winning streak since December 2023 — while the Nasdaq surged 8.5% for the month, its best monthly performance of 2026, driven by a semiconductor supercycle that pushed Micron Technology past a $1 trillion market cap (+19% on May 26th on a UBS price target of $1,625) and a Dell AI server earnings beat of historic magnitude ($43.8B revenue, +88% YoY). The regime's Transitional classification reflects the tension between this AI-earnings-powered equity bull and a macro backdrop of 3.8% headline PCE, a GDP that was revised down to 1.6%, record-low consumer sentiment at 44.8, and an Iran ceasefire MOU that remains unsigned — with Trump issuing fresh demands Friday and active ballistic missile exchanges continuing through the week. Today's ISM Manufacturing PMI for May (consensus 53.1, prior 52.7) is the first tier-1 data point of June and will frame the growth narrative heading into the critical June 5th NFP and June 17th FOMC.
Inflation
Prices are rising faster than the Federal Reserve — the central bank that sets interest rates — would like to see, and the trend has been getting worse, not better, over the past three months. The government's preferred inflation gauge showed prices up 3.8% over the past year in April, nearly double the Fed's 2% target, driven largely by higher gasoline costs tied to the conflict in the Middle East. There's one small encouraging sign: prices rose a bit less than expected month-to-month in April, hinting that the surge may be starting to level off. But here's what worries economists most right now — a major consumer survey found that Americans expect prices to keep rising at 4.8% over the next year, and their longer-term expectations are also climbing. When people expect higher inflation, they tend to demand higher wages and spend differently, which can make inflation even harder to bring down. Until gasoline prices fall meaningfully and stay down, the Fed is very unlikely to cut borrowing costs on mortgages, car loans, or credit cards.
Key Takeaway
Inflation is still running too hot for the Fed to cut rates — and Americans' expectations for future prices are rising, which makes the problem harder to solve.
The inflation picture entering June is unambiguously elevated and directionally unfavorable on an annual basis, even as the most recent monthly data offered a fragile constructive signal. April headline PCE rose 0.4% MoM, pushing the YoY rate to 3.8% — up from 3.5% in March and 2.8% in February, the highest reading since May 2023 — while core PCE held at 3.3% YoY on a softer 0.2% MoM print (consensus: 0.3%). The Q1 GDP second estimate embedded a PCE deflator of 4.5% annualized and a core PCE of 4.4% (revised up 0.1pp), confirming that Q1 inflation ran far hotter than the Fed's 2% target. Critically, the University of Michigan's final May consumer sentiment survey — released May 22nd at a record low of 44.8 — showed year-ahead inflation expectations at 4.8% and long-run expectations at 3.9%, the highest long-run reading in years, up sharply from the 2.8%–3.2% range that prevailed through 2024. Inflation expectation de-anchoring at the consumer level is the Fed's most feared secondary effect, and the May data moves closer to that threshold.
The composition of inflation remains structurally challenging. Energy remains the dominant impulse — gasoline drove the largest single-category contribution to April spending at +$28.8 billion — but the underlying core services trend is the longer-duration problem. The S&P Global Manufacturing PMI for May (released May 21st, preliminary) hit 55.3 — the strongest since May 2022 — but its embedded Prices Paid component showed input cost inflation at a ten-month high and output charges rising at the fastest pace since June 2025, signaling that producer-level inflation is broadening rather than abating. The ISM Manufacturing Prices Paid component has been running between 78–80 since March, among the highest readings since June 2022. The personal saving rate at 2.6% in April leaves little buffer for further nominal spending support, and with personal income essentially flat in April, real consumer purchasing power is compressing. The ceasefire-driven oil retreat from May highs (WTI off roughly 20% from its 2026 peak above $110) is the most meaningful potential disinflationary tailwind for H2 2026 — but it remains contingent on the MOU being formalized.
Key Takeaway
Inflation is reaccelerating on a YoY basis, consumer inflation expectations are near multi-year highs, and producer prices remain hot. The monthly core deceleration to 0.2% is insufficient to shift the Fed's calculus. Rate cuts are off the table for 2026; the operative question heading into Warsh's June 17 debut is whether the FOMC formally shifts to a tightening bias — a move that would represent the most significant policy signal of the year.
Risk and Positioning
Think of market conditions right now as a sunny day with distant storm clouds on the horizon — calm on the surface, but with real risks that haven't gone away. The market's fear gauge dropped to 15.31 on Friday, one of its lowest readings since the Iran war began, as stocks closed May at all-time highs for the ninth week in a row. The engine driving all of this is artificial intelligence: companies that make the computers, chips, and software that power AI have been reporting sales and profits that far exceed what anyone expected, and investors have responded by pushing their stock prices to historic levels. At the same time, everyday Americans are more pessimistic about the economy than at any point on record — a striking disconnect. Gold rose nearly 1% on Friday even as stocks hit new highs, which is unusual and suggests some investors are still quietly hedging against the possibility that the Iran peace deal falls apart.
Key Takeaway
Markets are at record highs and feeling calm, but the peace deal in the Middle East still isn't signed — if it falls apart, oil prices and inflation could spike quickly.
May closed with one of the most asymmetric risk-asset environments in recent memory: the S&P 500 at record highs, nine consecutive weeks of gains, and a VIX that settled at 15.31 — its lowest close since the Iran war began in late February — while consumer sentiment printed at an all-time record low and PCE hit its highest level in three years. The market has decisively chosen to price the AI earnings cycle over the macro headwinds, and the May data validated that choice: Dell's +33% single-session gain, Micron's +19% surge to a $1 trillion market cap on the UBS upgrade, and a Nasdaq up 8.5% for the month collectively represent the most powerful AI earnings vindication of the year. The forward 12-month P/E on the S&P 500 has likely re-rated above the 20.9x reading from early May, given the index's 5% monthly gain and substantial positive earnings revisions from the AI infrastructure complex. Stretched multiples are the structural risk, but the earnings revision cycle is currently running in the bull's favor: roughly 78% of Q1 reporters beat consensus, above the 74% 10-year average.
The risk positioning dynamic heading into June is defined by two competing forces. On the bullish side: AI infrastructure earnings momentum is broadening from hardware (Dell, Micron) to software (Snowflake +36%, ServiceNow +14%, Datadog +10%), the semiconductor index (SOX) is up 81% YTD and crossed 13,000 for the first time, and the XLK sector posted +19% for May alone (+32% YTD). Morgan Stanley's Daniel Skelly issued a note Friday warning the AI trade could cool in a "mid-1990s" scenario — a cautionary flag from a major institution that deserves weight. On the bearish side: the equal-weight S&P continues to underperform the cap-weighted index meaningfully, confirming megacap concentration risk; Energy (XLE) and Utilities (XLU) both fell over 5% in May as the ceasefire trade unwound the war premium; and consumer-facing sectors (Gap cut annual guidance, American Eagle failed to reassure) signal demand pressure at the lower-income consumer level. Gold at $4,540.53 (+0.99% Friday) tells a consistent story: geopolitical hedging demand has not fully dissipated even as equities celebrate.
The Iran MOU remains the single largest binary risk for markets in June. Trump issued fresh demands Friday on Hormuz navigation, Iran's nuclear program, and unfreezing of Iranian assets — conditions Iran has not accepted. Active military exchanges continued through Thursday, with ballistic missiles fired at Kuwait before interception. UBS noted that physical crude loadings through Hormuz remain "extremely low" with "little evidence" of improvement. The market is pricing a deal; the physical reality has not yet confirmed one. A ceasefire collapse would rapidly reprice WTI toward prior 2026 highs (above $110), reigniting the energy inflation shock and forcing a reassessment of the Fed's path and equity risk premiums simultaneously.
Key Takeaway
VIX at 15.31 and nine consecutive weekly gains reflect near-maximum near-term bullish consensus. The risks are asymmetric to the downside: a ceasefire collapse, a FOMC tightening signal at June 17, or any break in the AI earnings revision cycle could catalyze a sharp de-rating from stretched multiples. The bull case requires the MOU to hold and Dell/Micron-caliber AI beats to continue. Watch SPX 7,500 as near-term support and 7,600 as the key upside level.
Sector and Cross-Asset Analysis
May was almost entirely a technology story. Tech companies (XLK) surged 19% for the month — their best performance of 2026 — as the artificial intelligence boom produced a series of jaw-dropping earnings results. Micron Technology, which makes the specialized memory chips that AI systems require, crossed a $1 trillion valuation after jumping 19% in a single day when a major Wall Street firm nearly tripled its price target. Dell Technologies then rose 33% in one session after reporting nearly double the revenue analysts expected, driven entirely by demand for AI servers. Software companies like Snowflake and ServiceNow also surged, suggesting the AI spending wave is spreading from the hardware that runs AI to the software that uses it. On the other end, oil and gas companies (XLE) and utility companies (XLU) each fell more than 5% for the month as hopes for a Middle East ceasefire pushed energy prices lower — good news for consumers at the pump, but painful for energy investors.
Key Takeaway
AI is the only game in town right now — nearly every other part of the market lagged in May while tech dominated by a wide margin.
May's sector performance was one of the most concentrated and technically extreme in recent memory. Technology (XLK) gained +19% for the month and is now +32% YTD, driven by a semiconductor supercycle that saw the SOX cross 13,000 for the first time and Micron post +88% for the month — one of the most extraordinary single-month performances by a mega-cap stock on record. The catalyst sequence was decisive: the UBS price target upgrade on Micron to $1,625 (from $535) on May 26th triggered the $1 trillion market cap crossing; Dell's Q1 FY27 beat on May 28th ($43.8B revenue, +88% YoY, $16.1B in AI server sales) confirmed the AI capex cycle is a multi-company, multi-quarter structural phenomenon; and the subsequent software sector rally (Snowflake +36%, ServiceNow +14%, Datadog +10%) confirmed the broadening of AI monetization from hardware to applications. Healthcare (XLV) was the distant second-best sector in May at +2.4%. Every other sector — Materials, Communications, Financials, Industrials, Consumer Staples, and REITs — declined for the month, underscoring the extraordinary concentration of May's returns in technology alone.
Energy (XLE) and Utilities (XLU) were the worst-performing sectors in May, both falling over 5%, as the ceasefire-driven oil retreat removed the war premium that had been the primary bull thesis for the sector since February. WTI closed Friday at $90.07, down 1.14% on the session and down approximately 20% from its 2026 peak — the sharpest monthly decline in crude since the COVID-19 pandemic period. The front-month CL1! contract fell 1.73% to $87.36, while spot WTI's close above $90 reflects residual physical risk premium from the still-incomplete MOU. Defense stocks (LMT, NOC, GD, RTX) received positive S&P outlook revisions during the week, a structural re-rating that is independent of near-term ceasefire outcomes and reflects the multi-year defense spending cycle irrespective of how the Iran conflict resolves.
Cross-asset dynamics on Friday were constructive: the 10Y yield fell 1.6bps to 4.437%, completing a weekly yield decline that reflects ceasefire optimism reducing the energy-driven inflation premium. The 10Y/2Y spread at approximately +44 basis points (2Y at 4.002%) represents a positively sloped, gently steepening curve — consistent with growth expectations holding up marginally better than front-end rate fears. The DXY was essentially unchanged at 98.942, having declined approximately 2.5% from its late-April highs as the ceasefire trade reduced the safe-haven bid for the dollar. Gold's +0.99% gain to $4,540.53 on Friday — rising alongside equities at record highs — is the clearest signal that the geopolitical risk premium has not fully normalized: gold and equities are not typically both rising in a genuinely benign environment. Internationally, South Korea's Kospi and Japan's Topix both hit record highs during the week, confirming the AI semiconductor trade is a global institutional theme, not merely a U.S. equity phenomenon.
Key Takeaway
May's returns were a technology story — specifically a semiconductor/AI infrastructure story — in which XLK's +19% overwhelmed broad market mediocrity. As June opens, the question is whether the AI earnings broadening thesis (hardware → software → consumer gadgets) sustains the next leg, or whether Morgan Stanley's "mid-1990s AI cooling" warning marks a near-term sentiment ceiling. Breadth remains narrow; equal-weight underperformance is the primary structural caution flag.

Today's Calendar
- 8:00 AM MT — ISM Manufacturing PMI (May) — High Impact
Consensus: 53.1 | Previous (April): 52.7 | S&P Global Flash May PMI: 55.3
Week Ahead
The week builds to Friday's May Nonfarm Payrolls (June 5th, 6:30 AM MT) — the final major labor market read before the June 16–17 FOMC. Wednesday brings ADP Employment (6:15 AM MT) and ISM Services PMI (8:00 AM MT, consensus 53.7), and Thursday delivers weekly Jobless Claims and the Trade Balance. May CPI releases June 10th, completing the data set for Warsh's inaugural press conference on June 17th. The SpaceX (SPCX) IPO roadshow is expected to launch around June 4th, with pricing targeted as early as June 11th at a $1.75–$2T valuation.
The Bottom Line
Markets enter June riding a historic winning streak powered by AI, but this week's attention turns to jobs and the economy — because how those reports come in will shape what the Federal Reserve does with your borrowing costs on June 17th. The Iran peace deal remains the wild card: progress could push stocks and oil prices in opposite directions, and any breakdown would quickly change the mood.
Markets enter June with maximum momentum — nine straight weeks of gains, all-time highs, and an AI earnings cycle that continues to beat even aggressive expectations — but today's ISM Manufacturing PMI is the first test of whether the macro backdrop can keep pace with the equity narrative; a print above 53.1 with stable prices paid would be unambiguously constructive, while a reacceleration in the Prices Paid sub-index (which has run 78–80 since March) would reinforce the "higher-for-longer" Fed thesis and test Treasury yields against the 4.45% level. SPX support sits at 7,500 with resistance at 7,600; the bias is modestly bullish on the session given momentum and month-end positioning, but the Iran MOU's status over the weekend is the primary overnight risk factor — any signs of progress or collapse will drive the opening trade more than any domestic data point.
