The UAE Is Hit, Markets Fall: How the Iran Conflict Ended the April Rally

It took just 24 hours to flip the narrative. On Friday, the S&P 500 and Nasdaq closed at fresh all-time highs — 7,230.12 and 25,114.44. The April rally was the strongest since November 2020. Yet on Monday, May 4, markets sold off as the United Arab Emirates intercepted missiles from Iran, activating its early-warning system for the first time since the U.S.-Iran ceasefire began. The Dow lost 557 points or 1.13 percent, closing at 48,941.90. The S&P 500 fell 0.41 percent to 7,200.75, the Nasdaq Composite 0.19 percent to 25,067.80. Brent quotes jumped above $126 — the first four-year highs since Thursday. WTI climbed 3.4 percent to above $105. What had been treated as geopolitical background noise is suddenly the dominant theme again.

What Happened Over the Weekend

The escalation has a concrete backstory. On Sunday, May 3, President Trump announced an initiative called “Project Freedom” via a Truth Social post. The U.S., according to Trump, would “guide” stranded vessels through the Strait of Hormuz, which has been blockaded since the start of the Iran war — through a narrow route in Omani waters along the southwestern edge of the waterway. The strategic significance is enormous: the Strait of Hormuz is the world’s most important oil chokepoint. Roughly 20 percent of global oil supply passes through it daily.

The Iranian response was immediate. Tehran warned it would target U.S. forces approaching the waterway. Overnight into Monday, the UAE reported Iranian strikes against the major oil export terminal of Fujairah and several ships in and around the Strait of Hormuz, including an oil carrier belonging to the Abu Dhabi National Oil Company. Fujairah was not hit by accident — the port, fed by a pipeline from the Persian Gulf to the Gulf of Oman, has become the key release valve for oil stuck behind the Strait of Hormuz.

The Market Reactions in Detail

The energy sector was the only winner of the day. The S&P 500 Energy Index gained 0.6 percent — the only of the eleven sectors in positive territory. APA led the sector winners with nearly 4 percent, Diamondback and Marathon Petroleum followed at about 3 and 2 percent. SLB, which leans more heavily on services, fell over 2 percent.

AI infrastructure names that had carried the April rally came under the heaviest pressure. Nvidia, Broadcom, AMD, Qualcomm, and Intel lost between 1.5 and 6 percent. This reaction is revealing: AI stocks are more correlated with risk sentiment than many investors realize. When geopolitics intensifies and 10-year Treasury yields jump as they did Monday by 6 basis points to 4.438 percent, highly valued growth names get sold first.

Berkshire Hathaway was among the broad-market losers — and that’s despite the strong Q1 numbers from over the weekend. Greg Abel’s first quarter as CEO ended with operating earnings growth of 18 percent and a cash position approaching $400 billion. But in an environment of rising Treasury yields, even defensive names get sold.

Palantir After the Closing Bell

Amid the broader weakness, Palantir delivered a bright spot after Monday’s close. The AI software provider reported record revenue and record profit in the first quarter. The stock gained 1.4 percent in regular trading after the report and added another 0.4 percent in premarket. This is relevant for the May week: Palantir was one of two critical earnings tests this week. AMD on Tuesday will be the second. If both deliver, bulls get arguments to read the correction as a buying opportunity. If they disappoint, multiple compression at the hyperscalers accelerates.

The Mortgage Market Becomes a Leading Indicator

An often overlooked detail: Average 30-year mortgage rates climbed back above 6.5 percent on Monday — to 6.52 percent — and thus to the highest level in over a month. The 8-basis-point increase tracked almost 1:1 with the 10-year Treasury yield’s move. High mortgage rates are not just a housing market problem. They reflect bond investors’ inflation expectations — and if these rise because oil prices won’t come back down, then the Fed cannot cut. Markets currently price essentially zero rate cuts for 2026.

Historical Seasonality Speaks Clearly

May traditionally marks the beginning of a historically weak six-month period for stocks. The S&P 500 has gained only an average 2 percent between May and October since 1945. “Sell in May and Go Away” is a tired saying, but the data behind it is real. Adam Parker of Trivariate Research noted in a Sunday memo that the S&P 500’s April performance was the 25th strongest in the last 1,167 months — an event that statistically occurs every 56 months. “Bracing for a market pullback” is currently appropriate for investors.

This Week’s Dates Will Be Decisive

Several key data points are due this week. AMD on Tuesday — the most important semiconductor test of the week, with the stock already up 270 percent year-over-year. Options traders are pricing in a 7-percent move in the stock after the report. Coinbase and Disney on Thursday. McDonald’s on Wednesday. Over 100 S&P 500 names report this week in total.

Outside earnings: The ISM Manufacturing PMI for April held at a four-year high of 52.7 on Friday — a clear positive signal for the U.S. economy. ISM Services comes Tuesday. Nonfarm Payrolls on Friday will show whether the labor market can withstand the geopolitical pressure.

SpaceX as Market Catalyst

A larger story on the periphery: SpaceX is preparing an IPO at a valuation of up to $1.75 trillion. That would be the largest IPO in history. Brad Gerstner of Altimeter Capital warned on Monday that retail investors should not expect to get rich from the IPO — “buying a company at a trillion dollars in value, or a trillion-and-a-half dollars in value, is not a get-rich-quick scheme.” Still, retail and institutional investors could see solid returns by accumulating SpaceX stock after the listing.

What Retail Investors Should Do Now

Three points are decisive from a risk management view. First: the Iran escalation is not just “geopolitics” — it’s a direct driver of inflation and thus of Fed policy. Anyone running a savings plan should not stop it; let it continue. Volatility delivers more favorable entry levels.

Second: the AI trade is not dead, but it’s temporarily dependent on risk sentiment. AMD’s report Tuesday is the next test. If AMD delivers, the AI trade returns. If AMD disappoints, the correction accelerates.

Third: energy stocks are short-term advantaged but cyclical. Anyone entering now is buying at multi-year highs. Smart money positions differently — through long-term exposure to energy infrastructure, not through speculation on further escalation.

Bottom Line

The April rally was extraordinary, but it created a market position that now responds sensitively to any escalation. The Iran-UAE confrontation has not erased the gains — the S&P 500 is still 7.5 percent above its 52-week low. But the narrative has changed. Instead of “the worries are exaggerated,” it’s now “the worries are back.” The next 72 hours — AMD Tuesday, ISM Services, Coinbase, and Disney — will reveal whether the correction densifies into a serious pullback or whether the next buying impulse is already at the door. Stay sober, stick to the plan, and use volatility when it’s there.
