U.S. equity markets delivered a mixed close on Monday, with the tech-heavy Nasdaq edging higher while the Dow and small-cap stocks retreated, as investors weighed escalating geopolitical tensions in the Middle East against a flurry of corporate news and insider buying activity.

The Nasdaq 100 (QQQ) bucked the broader trend, rising 0.22% to $716.71, and the Russell 2000 (IWM) declined 0.40% to $293.92.

## Oil Surges as U.S.-Iran Tensions Boil Over
The dominant macro story on Monday was the sharp escalation in geopolitical risk. Oil prices traded sharply higher after the United States launched strikes on Iranian rocket launchers on Larak Island, prompting Iran to retaliate with attacks on U.S. bases in Jordan. The developments sent crude benchmarks higher and fueled a flight to safe-haven assets, while energy stocks caught a bid on supply disruption fears.
The geopolitical shockwave reverberated through several sectors, with defense and energy names seeing increased attention. The United States Oil Fund (BNO) rallied on the news, reflecting the market's pricing of a risk premium on crude supplies from the strategically vital Strait of Hormuz region.
## Sector Spotlight: Energy Rises, Utilities Lag
Energy stocks were the clear outperformers as crude prices surged. The geopolitical premium injected fresh momentum into a sector that had been under pressure in recent weeks. Conversely, utilities and rate-sensitive sectors faced headwinds as the geopolitical uncertainty weighed on risk appetite, though the tech-heavy Nasdaq managed to hold its ground.
## Biggest Movers: Biotech, Crypto, and a YouTuber Shake Things Up
Monday's session was marked by extraordinary volatility in several names, driven by a mix of regulatory catalysts, earnings surprises, and notable shareholder activism.
Antelope Enterprise (AEHL) surged over 100% in what appeared to be a pump-driven rally, though the company did not release any material news to justify the move. USDE jumped 30.92% to $8.85 on heavy volume of 8.8 million shares, while TP gained 28.12% to $10.25.
On the downside, MOVE cratered 26.08% to $11.00, and WETO tumbled 22.85% to $5.51 on massive volume of nearly 37 million shares.
GoPro (GPRO) was a standout winner, soaring 11.85% to $9.96 after reports emerged that YouTube star Markiplier had become the company's largest shareholder. The development injected fresh optimism into the struggling action-camera maker, with traders betting the influencer's involvement could revitalize the brand.
Bitdeer AI (BTDR) gained after announcing it had sold out 9.5MW capacity at its Malaysia data center, securing over $800 million in five-year offtake commitments ahead of Q1 2027 energization. The news underscored growing demand for AI infrastructure.
Roivant Sciences (ROIV) rose after the FDA cleared the first targeted treatment for dermatomyositis, a rare autoimmune disease. The approval marked a significant milestone for the company and its pipeline.
SciSparc (SPRC) traded higher after its subsidiary NeuroThera Labs advanced participant enrollment in a clinical trial for SCI-210, a treatment for autism spectrum disorder symptoms.
PMV Pharmaceuticals (PMVP) saw volatile trading after announcing the commencement of an underwritten public offering, which weighed on shares, but the stock also reported promising interim Phase 2 data showing a 46% overall response rate in TP53 Y220C ovarian cancer patients. The company plans to submit an NDA in Q1 2027.
Editas Medicine (EDIT) fell after filing a prospectus for a $400 million mixed shelf offering, raising dilution concerns.

## Smart Money: Insider Buying Spree

## Looking Ahead
Investors will be closely watching developments in the Middle East, with any further escalation likely to drive continued volatility in energy markets and defensive sectors. On the economic calendar, Tuesday brings the ISM Manufacturing PMI for August, which will provide the latest read on factory activity. The data will be scrutinized for signs of whether the manufacturing sector is stabilizing after months of contraction.
Additionally, the market will digest the flurry of insider buying activity, which historically has been a bullish signal for the stocks involved. Earnings season is winding down, but a few notable reports remain on the calendar.
The tech-heavy Nasdaq's resilience in the face of geopolitical headwinds suggests that investor appetite for growth stocks remains intact, though the broader market's inability to hold gains points to lingering caution. With the Federal Reserve's next policy meeting approaching, any shift in rate expectations could quickly alter the market's trajectory.
