  • President Donald Trump intensified warnings toward Iran, pushing crude prices near two-week highs. 
  • Reports indicated Trump is expected to hold a Situation Room meeting on Tuesday with top national security officials to discuss possible military options. 
  • The cautious tone comes ahead of one of this week's biggest catalysts: NVDA's earnings on Wednesday.

U.S. stock futures were under pressure early Monday after wrapping a record-setting week. Investors monitored the rising U.S.-Iran tensions and a heavy earnings week, which includes a report from the bellwether for AI demand: Nvidia. 

Crude oil prices hovered near two-week highs after President Donald Trump issued stern warnings to Iran. Trump is expected to hold a Situation Room meeting on Tuesday to discuss military options, stating that Iran must present a better offer or face a "much harsher strike." 

Meanwhile, on Sunday night, the White House announced multiple trade deals following a meeting between President Trump and China’s President Xi Jinping. China has agreed to address rare-earth supply shortages, purchase 200 Boeing aircraft, buy $17 billion in U.S. agricultural goods annually, and restore access to U.S. beef and poultry. 

As of 4:00 a.m. ET on Monday: Dow futures fell 0.7%, S&P 500 and Russell 2000 futures were 0.6% lower, and Nasdaq futures declined 0.5%.

Retail sentiment toward the SPDR S&P 500 ETF (SPY), an exchange-traded fund that tracks the S&P 500 Index, has held at ‘extremely bullish’, while the Invesco QQQ Trust (QQQ) ETF, which tracks the Nasdaq-100 Index, has improved to ‘extremely bullish’ from ‘bullish’ last week. 

Trending Stocks To Watch

Nvidia (NVDA) is garnering retail attention ahead of Wednesday’s earnings report. Traders are expecting another strong quarter, though some skepticism remains after the stock’s recent AI-driven rally. 

ServiceNow (NOW): Its recent $4B debt raise and the revelation last week that President Trump holds a stake in the company brought renewed attention. Retail traders believe that ServiceNow is one of the undervalued stocks in the space and has potential for rally ahead. 

ImmunityBio (IBRX) stock rose 2% in early premarket trade ahead of a pivotal FDA workshop regarding its drug Anktiva and a new exclusive U.S. supply agreement with Japan BCG Laboratory for bladder cancer treatments. 

UnitedHealth (UNH) shares fell 5% in premarket trading after Berkshire Hathaway disclosed it fully exited its $1.6 billion stake during the first quarter. Retail traders on Stocktwits largely dismissed the move, arguing Berkshire sold near the lows before missing UNH’s powerful 45% rebound.

Regeneron Pharmaceuticals (REGN) stock fell 11% in early premarket trade after a Phase 3 melanoma trial failed to meet its primary endpoint tied to progression-free survival. Piper Sandler has lowered its price target on Regeneron to $855, down from $875. 

Poet Technologies (POET): Stock recovered from Friday’s selloff. Traders appeared to be setting positions ahead of Nvidia’s quarterly report later this week. For context, Nvidia’s mention of photonic tech has often triggered gains in POET stock.

Dominion Energy (D) shares rose 11% in early premarket trade on reports that NextEra Energy (NEE) is in talks to acquire the company in a mostly stock deal to form a $400 billion utility titan.

Other tickers trending on Stocktwits at the time of writing included Redwire Corp (RDW), Everspin Technologies (MRAM), AST Spacemobile (ASTS) and Iren Limited (IREN). 

Other Catalysts To Watch

On earnings radar, watch out for quarterly reports from Baidu (BIDU), iQIYI (IQ), Axe Compute (AGPU), and Niu Technologies (NIU), among others, before the bell today. Major retail earnings from Walmart and Target will follow later in the week.
