March 26, 2026
Thursday in 30 seconds:
Worst day since the conflict began — SPX -1.7%, tech -2.4%, small caps -1.7% — as re-escalation fears returned with force
Three catalysts hit simultaneously: Pentagon reportedly preparing a “final blow” strike plan on Iran, Trump signaling he may not commit to a deal, and Trump downplaying the market impact of the war
Everything that rallied on Sunday got sold today — AI stocks, cyclicals, momentum, gold, and high yield bonds all fell hard
Momentum stocks had their worst single day in recent memory: -4.7% — a sign of broad, indiscriminate de-risking
After the close, the US extended the energy infrastructure ceasefire by 10 days — but markets barely moved, closing near session lows
The week is now essentially flat on SPX — Sunday’s relief rally has been almost entirely erased
All eyes on Iran’s 5-point counterproposal and whether talks continue into the weekend
This round-trip dynamic is exactly what we warned about in earlier notes, linked here. With dealer gamma flat at current prices and positioning dynamics favoring choppiness over trend, the market was always more likely to oscillate than to establish a clean directional move. This week has been a prime example.
Let’s get into it.
What Happened Today
Three days ago, a single Trump statement about “very good and productive conversations” with Iran sent markets surging. Today, three separate pieces of news from the same administration reversed nearly all of it.
The sequence mattered. First, Axios reported that the Pentagon is developing military options for a “final blow” against Iran — signaling that the US military posture hasn’t softened even as diplomacy was supposedly underway. Then, President Trump told reporters he may not commit to an agreement. Then, in what may have been the most market-damaging comment, Trump downplayed the war’s impact on markets — a signal that he isn’t particularly focused on financial stability as a constraint on his foreign policy decisions.
Markets read all three signals the same way: the ceasefire was fragile, the diplomacy was uncertain, and the Commander-in-Chief wasn’t treating market stability as a binding constraint. The selloff was quick and broad.
The After-Hours Ceasefire Extension
After the market close, the US announced it was extending the ceasefire on Iranian energy infrastructure by 10 days. In isolation, this should have been positive news. In practice, markets barely moved — SPX futures closed near the session lows.
Why the muted reaction? Because the context surrounding the extension overwhelmed the headline itself. When the same administration that extended the ceasefire also had the Pentagon reportedly preparing a “final blow” and the President signaling he may not commit to a deal, a 10-day extension reads less like diplomatic progress and more like a procedural pause before potential escalation. Markets are pricing the totality of the signals, not just the most recent one.
The fact that SPX futures closed near the lows after the after-hours news is itself a signal. In a market that’s looking for reasons to rally, good news would have been seized upon aggressively. Instead it was shrugged off — a sign that the macro mood has shifted back toward skepticism and caution.
2-Year Yields Approaching 4%
The bond market’s reaction today deserves careful attention because it tells us something specific about how investors are interpreting the re-escalation.
The 2-year Treasury yield jumped 10 basis points to 3.98% — approaching the psychologically significant 4% level. The 10-year yield also rose, but the front end moved more aggressively.
Why Does the 2-Year Yield Matter So Much Right Now? The 2-year Treasury yield is the bond market's best real-time read on near-term Federal Reserve policy. When it rises, markets are pricing out rate cuts — they're saying the Fed will keep rates high for longer. At 3.98%, the 2-year is approaching a level that would represent a significant repricing of Fed expectations. The 4% level is a technical and psychological threshold that, if broken convincingly, would signal that markets have largely abandoned hopes for near-term rate cuts. For stocks — especially high-growth tech — this is a direct headwind, because their valuations depend heavily on the assumption that rates will come down.
The re-escalation → oil risk up → inflation fears up → Fed stays tight → rates higher chain is running again. Sunday’s oil decline provided temporary relief on this front. Today’s re-escalation fears are reversing it. This is why stocks and rates moved together today — they’re responding to the same underlying driver.
High Yield Spreads Widen — The Credit Market Sends a Warning
High yield credit spreads widened +13 basis points today — a meaningful single-day move that deserves its own section.
What Are High Yield Spreads and Why Do They Matter? High yield (HY) bonds are debt issued by companies with lower credit ratings — sometimes called "junk bonds." The "spread" is the extra interest rate these companies must pay above what the US government pays to borrow. When spreads widen, it means lenders are demanding higher compensation for the risk of lending to these companies — a sign of rising anxiety about corporate health and the economic outlook. A +13bp single-day widening is notable. It's not crisis-level, but it's the credit market beginning to price in genuine economic stress. Historically, sustained HY spread widening precedes equity market deterioration — the credit market often leads stocks as a warning signal.
The significance of HY spreads widening on the same day that stocks fell sharply is that it represents a multi-asset confirmation of the risk-off signal. When equities fall in isolation, it can be a positioning or technical move. When equities and credit and rates all move in the same direction simultaneously, it reflects a genuine shift in the fundamental outlook. Today had all three.
Gold Failed Again — What It’s Telling Us
Gold fell -3% today. For investors who view gold as the ultimate safe haven — the asset that always goes up when everything else falls — this is confusing. It’s actually the second time in recent sessions that gold has declined alongside stocks.
When traditional safe havens fail to protect portfolios, it typically signals one of two things: either the selling is purely mechanical and technically driven (forced de-risking regardless of asset quality), or the market is repricing a fundamentally new and more negative scenario where even safe assets look less attractive. Today’s gold decline alongside HY spread widening and equity weakness suggests the former — broad, indiscriminate de-risking — but warrants monitoring.
The Momentum Collapse with -4.7% in One Day
The momentum factor’s -4.7% single-day loss is the most technically significant data point. We flagged in a previous edition that the momentum long leg had a -50% correlation to oil — meaning when oil rises, momentum longs tend to fall. Today’s re-escalation, with its implications for oil prices, acted as a direct catalyst for momentum de-risking. Critically, the Morgan Stanley desk had been explicitly cautious on momentum longs heading into this period. The previous two major momentum drawdowns averaged -32% — and the current drawdown is just getting started from a historical context perspective.
The AI Unwind — The Market’s Last Consensus Trade Cracks
The most striking development today wasn’t the overall market decline — it was the severity and breadth of selling in AI-related stocks, which had been the market’s most resilient theme throughout the conflict.
The MSXXCLAW basket opening higher before reversing to -2.2% is a particularly telling detail. Early buyers who tried to “buy the dip” in the morning got stopped out as selling accelerated through the day. That kind of intraday reversal — from green to red on previously resilient names — is characteristic of a sentiment shift from “AI is immune to macro” to “nothing is immune when re-escalation hits this hard.”
Growth vs. Value Hits a 2-Year Low — A Structural Signal
Growth vs. Value Stocks: Growth stocks are companies expected to grow revenues and earnings faster than average — typically tech, AI, biotech, and consumer internet names. They trade at high valuations because investors are paying for future earnings. Value stocks are companies trading cheaply relative to their current earnings or assets — typically financials, energy, industrials, and consumer staples. The relative performance of growth versus value is one of the most closely watched macro signals on Wall Street, because it reflects the market's view on interest rates, economic conditions, and risk appetite. When growth underperforms value, it usually means rates are rising and/or investors are de-risking away from speculative names.
A 2-year low in growth-versus-value is not a one-day anomaly. It’s the cumulative result of a sustained repricing. The high-rate, high-inflation environment that the Middle East conflict is perpetuating is fundamentally hostile to growth stock valuations, which depend on discounting far-future earnings at low rates. Every day that the 2-year yield pushes toward 4% is another day that the mathematical case for paying high multiples for growth companies gets harder to justify.
