Well, that was a mood swing. Financial markets, which had been nervously eyeing the Middle East, decided to throw a party on Wednesday after the U.S. paused military action against Iran. It was a classic risk-on move: stocks up, oil down, and a collective sigh of relief echoing from trading desks.

Stocks Surge As Risk Sentiment Rebounds
U.S. stock futures jumped early Wednesday after President Donald Trump announced a two-week suspension of attacks on Iran. It was the kind of news that makes algorithms happy. Dow futures rose 1,056 points, while S&P 500 and Nasdaq 100 futures gained 2.45% and 3.2%, respectively.
Where did the money go? Straight into the usual suspects. U.S. Big Tech giants Meta Platforms Inc (META), Apple Inc (AAPL), Amazon.com Inc (AMZN), and Alphabet Inc (GOOGL) opened higher in premarket trading as investors decided equities were back in fashion.
The gains didn't stop there. They spread like wildfire across the semiconductor space, which had taken a hit earlier in the week. Suddenly, chip stocks were the place to be. Nvidia Corp (NVDA), Advanced Micro Devices Inc (AMD), Broadcom Inc (AVGO), Intel Corp (INTC), Arm Holdings Plc (ARM), Marvell Technology Inc (MRVL), Taiwan Semiconductor Manufacturing Co. Ltd (TSM), Micron Technology Inc (MU) and ON Semiconductor Corp (ON) all gained in tandem. It was a full-scale reversal.
This wasn't just a U.S. story. Global equities followed suit, with Asian and European markets posting strong gains as investors around the world welcomed the reduced risk of escalation and rotated capital back into stocks.
Jay Woods, chief market strategist at Freedom Capital Markets, told CNBC on Wednesday that the move was partly anticipated, noting, “It wasn’t much of a surprise that there was an announced reprieve in the Iranian conflict.”
“The market has gotten much better at sniffing out” Trump’s next move, he added. But then came the caveat, the thing everyone is whispering about: “The concern now is if this all too familiar ‘two-week’ timeframe is going to lead to a resolution.” In other words, enjoy the rally, but maybe don't get too comfortable.
Oil Plunges As Energy Supply Fears Ease
If stocks were the party, the oil market was the hangover cure. Crude prices dropped sharply after the ceasefire announcement, with West Texas Intermediate falling more than 15% and Brent crude losing over 13%, both slipping below $100 per barrel.
Why the plunge? The agreement raised expectations that the Strait of Hormuz—that crucial pinch point for global energy shipments—would reopen. The supply concerns that had been propping up oil prices during the conflict suddenly looked less urgent. It was a classic case of the geopolitical risk premium evaporating.
Koen Hoorelbeke, investment and options strategist at Saxo Bank, told the Wall Street Journal on Wednesday, “The geopolitical risk premium that had accumulated over 26 trading days of conflict is now unwinding at speed.” However, he struck a note of caution that mirrored the stock market's underlying anxiety: a two-week ceasefire “does not constitute a durable resolution.” It's a pause, not a peace treaty.
Price Action
So, what did the rally actually look like in the numbers? In Wednesday’s premarket session, the moves were decisive. Major tech and chip stocks rallied hard: Meta Platforms jumped 4.86% to $602.99, Alphabet gained 4.14% to $318.11, Nvidia rose 3.77% to $184.81, Broadcom climbed 5.34% to $351.80, and Marvell Technology surged 6.66% to $116.67, according to market data.
The story of the day is clear: markets hate uncertainty more than almost anything, and a ceasefire—even a temporary one—counts as a reduction in uncertainty. But the subtext is just as clear: everyone is watching the calendar. The rally is built on a two-week timeline. The question for investors is what happens when those two weeks are up.
