The Rally That Refuses to Make Sense

The S&P 500 closed at 7,609.78 on Tuesday, June 2. That was its fifth straight all-time high and the 23rd record close of the year. The index has climbed roughly 29% from where it sat twelve months ago, when it was hovering near 5,900. A year ago, inflation was still sticky, the Federal Reserve was talking about patience, and the US was not at war with Iran. Now it is, and the market does not care.

Or rather, the market cares about something else more.

The Earnings Engine That Won't Quit

J.P. Morgan Private Bank released its Mid-Year Global Investment Outlook on May 11 under the title "Promise and Pressure." The framing feels right for the moment. The promise is on full display in quarterly reports. Wall Street analysts now project S&P 500 earnings per share of $340 for the full calendar year 2026, a 24% increase from 2025. Goldman Sachs raised its year-end S&P 500 target to 8,000 from 7,600 on the back of that earnings trajectory. The rally, as Goldman's research team put it, has been powered entirely by profit growth rather than multiple expansion. That is the kind of detail that separates a durable bull market from a speculative one.

And yet.

The Liquidity Drain Nobody's Watching

The pressure side of J.P. Morgan's equation shows up in fixed income. The 10-year Treasury yield sat at 4.55% on June 5, up from 4.47% two days earlier but still within the range that has held for most of the past year. The yield curve has normalized somewhat, which sounds like good news until you remember what normalization means. Short term rates stayed elevated while long term rates refused to collapse. The 30-year bond yielded 4.97% on June 4. That is not a landscape of easy money. That is a landscape where the cost of capital has reset permanently higher and the market is still learning to walk on it.

Bond yields fell in May as inflation fears ebbed. The CPI data for April showed a 0.2% month over month increase, below consensus, and the market grabbed the headline like a lifeline. But the structural picture has not changed. Energy supply disruption from the Iran conflict continues to push input costs higher. The bond market is pricing in maybe one rate cut from the Fed before year end. Maybe. The ECB, meanwhile, is moving in the opposite direction.

Europe Takes the Hawkish Crown

The European Central Bank kept its deposit facility rate at 2.00% in April but signaled clearly that a hike was coming. Market expectations now point to a June move to 2.25%, with further tightening possible in July. The ECB has become the G7's lead hawk, a role that seemed improbable two years ago. Euro area inflation is running around 3%, above the 2% target, and energy prices tied to Middle East tensions have made the Governing Council's life harder. Policymakers in Frankfurt are watching the same oil charts the rest of us are. The Strait of Hormuz remains a flashpoint. Every tanker that transits it carries a risk premium that shows up in European heating bills and, eventually, in European inflation prints.

The irony is that US equity markets have largely shrugged this off. The logic goes something like this: European weakness does not derail US earnings when the largest US companies generate 40-50% of their revenue domestically and the rest from a global economy that, outside Europe, is still growing. The AI capex cycle shows no signs of slowing. OpenAI is plotting what is being called the biggest ChatGPT overhaul since the platform's launch, and the infrastructure spending that supports that race flows through the P&Ls of US tech giants. Those giants, in turn, dominate the S&P 500's market cap weight. The index has become a bet on maybe 50 companies, and those companies are printing money.

The Iran Factor Nobody Wants to Price

Here is where the story gets uncomfortable. The US and Iran are about 100 days into a war that has already reshaped energy markets and the geopolitical landscape of the Middle East. Reports from late May suggested a peace deal was close, with a memorandum of understanding nearing finalization. President Trump said negotiations were going "very well." Iranian officials pushed back, saying talks remained stalled. On May 24, Trump warned that "the clock is ticking" for a deal. Then he said he would "hold off" on a planned attack, citing a request from intermediaries.

The market has chosen to believe in resolution. J.P. Morgan's outlook explicitly states that "the risks are skewed in favor of a resolution to both the geopolitical conflict and market volatility as policymakers in the United States and China have a common desire to" maintain stability. That is not a prediction. It is a weighting. The market is assigning a higher probability to peace than to escalation because the alternative is too disruptive to model.

But disruption does not require a high probability to inflict damage. It requires a tail event that markets have not fully hedged. The VIX has drifted lower. Credit spreads have tightened. The market is acting like the Iran question is a solved problem. It is not. The mechanism by which Iran would dispose of its highly enriched uranium remains under negotiation. The Strait of Hormuz reopening is expected under the ceasefire framework but has not happened. Every day that passes without a deal is a day the risk premium on oil could re-emerge without warning.

What the Bond Market Is Really Saying

The Treasury market's behavior this spring offers a more nuanced read. The 10-year yield held in a range of roughly 4.0% to 4.5% for most of the past year before breaking above that band in late May. The move higher reflected not inflation panic but supply reality. The US government is issuing a lot of debt. The fiscal deficit, while improved from pandemic peaks, remains structurally elevated. Foreign buyers of Treasuries are not stepping in with the same enthusiasm they showed a decade ago. The marginal buyer of US government debt is increasingly the domestic investor, which means yields need to clear a higher bar to clear supply.

This is not a crisis. It is a structural adjustment that has been underway since 2022. But it matters for the equity rally in a specific way. Higher risk free rates create a higher discount rate for future earnings. If the S&P 500's earnings growth decelerates in 2027, as some models suggest, the math on current valuations gets tighter. Goldman projects EPS of $385 in 2027, up from $340 this year. That is still strong but the rate of deceleration from 24% to about 13% would be noticeable. Markets can absorb deceleration. They struggle with deceleration plus rising rates.

The AI Supercycle as Shield

The counterargument to all of this caution is the AI investment cycle. It is real, it is global, and it is accelerating. J.P. Morgan's outlook identifies "the rapid artificial intelligence supercycle" as one of the forces reshaping global markets. The infrastructure buildout alone has created a floor under capital spending at the largest technology companies. Data centers, semiconductor fabrication plants, energy grids being reconfigured to handle compute loads that did not exist three years ago. The scale is hard to overstate. Analysts at several major banks have compared it to the early days of the internet or the electrification of the US economy in the early 20th century.

Those analogies are useful but imprecise. The internet buildout ended in a bust because capital was allocated to companies with no business models. The AI buildout, so far, has flowed to companies with enormous cash flows and proven revenue models. That does not guarantee a soft landing. It does mean the comparison to 2000 is probably wrong. The more relevant historical parallel might be 1995, when the internet was real but most people had not yet understood how it would transform industries. The dislocation came later, and it came from adoption patterns no one predicted.

The Dollar's Quiet Role

One factor that has received less attention is the dollar. It has remained stable through the first half of 2026, and J.P. Morgan's outlook expects that stability to persist. A stable dollar matters for the equity rally because it allows emerging market economies to service dollar denominated debt without compounding stress. It matters for inflation because a steady dollar keeps imported goods from adding to price pressure. It matters for corporate earnings because multinationals do not have to contend with an adverse currency headwind of the kind that plagued them in 2022.

Stability, however, is not the same as strength. The dollar is stable at an elevated level. That creates its own set of pressures for countries whose currencies have depreciated against it. The global fragmentation that J.P. Morgan cites as a theme is partly a story of countries trying to reduce their dependence on dollar denominated trade. It is slow moving. It does not show up in quarterly GDP prints. But over a five to ten year horizon, it reshapes capital flows in ways that are hard to reverse.

The Structural Bull Case

Let me lay out the bull case in plain terms because it is stronger than many skeptics want to admit. Corporate earnings are growing at a double digit pace. The AI investment cycle has multiyear visibility. The Federal Reserve is not actively tightening. The US labor market remains resilient with unemployment below 4%. Consumer balance sheets, while stretched at the lower end, are not showing the kind of deterioration that typically precedes recession. The US economy is growing at or above trend. None of that is controversial.

The question is not whether these conditions are good. They are. The question is whether they are good enough to justify the prices investors are now paying. The S&P 500 trades at roughly 22 times forward earnings. That is above its historical average of about 17. It is not at dot com bubble extremes, which saw multiples above 30. But it is expensive by any reasonable historical standard. The bull case requires that earnings continue to grow at an above trend pace for several more years. That can happen. It has happened before. But the margin for error shrinks as prices rise.

What the Next 12 to 18 Months Probably Look Like

Forecasting is a fool's errand, but framing probabilities is not. The most likely path over the next 12 to 18 months involves continued equity gains driven by earnings, intermittent volatility tied to geopolitical headlines, and a gradual stabilization of bond yields in a range that makes both stocks and bonds simultaneously unattractive on a relative value basis. That is the hallmark of a mature bull market. The easy money has been made. The remaining gains will require patience and tolerance for drawdowns.

Goldman Sachs Research described this dynamic clearly when it noted that the 2026 rally has been powered entirely by profit growth rather than rising valuations. That is a healthy foundation. But it also means that if earnings disappoint, there is no valuation cushion to soften the fall.

The market has not priced in a lot of bad news. It has priced in continued good news with occasional interruptions. That is a reasonable baseline, but it is not a resilient one.

The JP Morgan team put it simply. There is promise in the earnings cycle, in the AI transformation, in the stability of the dollar and the resilience of the consumer. There is pressure from inflation that has not fully receded, from geopolitical fragmentation that has not resolved, from fiscal deficits that have not been addressed, and from valuations that leave little room for error. The tension between those forces is what defines this market. It is not a moment for conviction. It is a moment for balancing.

And that is the part that makes the rally feel strange even as it hits new highs. The market is not wrong to rally. The earnings justify it. But the market is also not fully reckoning with the fragility of the conditions that support those earnings. The Iran talks could collapse. The ECB could trigger a credit event in European periphery debt. The AI capex cycle could produce a glut of compute capacity that drives down returns on investment. Any of those could happen. None of them have to. But they are not priced in, and that is what makes this moment feel less like a celebration and more like a watchful pause.

The S&P 500 closed at 7,609.78 on Tuesday. It could go higher. It could also go lower. What it cannot do is stay exactly where it is. The pressure is building. The rally is real. The tension is unresolved. That is the story of this market, and it will remain the story until something breaks one way or the other.
