US Market Drivers

Markets are once again looking to the Middle East, with hopes for a peace deal between the U.S. and Iran reignited after Trump said in a post on Truth Social that he had paused a planned strike on Iran amid “serious negotiations.”

“I have been asked by the Emir of Qatar, Tamim bin Hamad Al Thani, the Crown Prince of Saudi Arabia, Mohammed bin Salman Al Saud, and the President of the United Arab Emirates, Mohamed bin Zayed Al Nahyan, to hold off on our planned Military attack of the Islamic Republic of Iran, which was scheduled for tomorrow, in that serious negotiations are now taking place, and that, in their opinion, as Great Leaders and Allies, a Deal will be made, which will be very acceptable to the United States of America, as well as all Countries in the Middle East, and beyond,” he said.

Trump reiterated that the deal would include “NO NUCLEAR WEAPONS FOR IRAN” and that the U.S. Military would stand by for “a full, large scale assault of Iran, on a moment’s notice,” if an acceptable deal was not reached.

Meanwhile, technology stocks declined sharply on Monday, led by key memory chip names. Seagate Technology shares fell nearly 7% after CEO Dave Mosley said at a JPMorgan conference that building new factories “would just take too long,” further adding to broader supply-chain concerns that were already under pressure. Other stocks, including Micron, SanDisk, Western Digital, and other AI-adjacent stocks also declined.

On the economic front, markets will be looking out for April’s pending home sales reading on Tuesday, and the minutes of the Federal Reserve’s May FOMC meeting, scheduled for release on Wednesday.

Trending Stocks To Watch

Dominion Energy (D): Shares of the energy company shot onto the retail radar after an announcement that NextEra Energy (NEE) would acquire the company in an all-stock deal worth nearly $67 billion. D stock closed up nearly 10% higher on Monday and continued to climb in the overnight session.

NextEra Energy (NEE): The Florida-based company also garnered attention amid the deal, which will create one of the world's largest electric utility companies. The stock, however, closed more than 4% lower, although it was edging higher in after-market hours.

Duos Technologies Group Inc. (DUOT): The small-cap tech company fell more than 5% on Monday after its first-quarter results missed Wall Street expectations.

T1 Energy Inc. (TE): The solar and battery manufacturer’s shares surged more than 23% on Monday and continued to climb higher in the overnight session after hedge fund Situational Awareness LP reported a new stake in the company.
