Market Analysis
U.S. stocks fell across the board on Thursday as investors digested the latest round of corporate earnings and monitored whether U.S.-Iran peace negotiations were making progress. The Dow Jones Industrial Average dropped 464.02 points, or 0.85%, to 53,885.10. The S&P 500 slipped 13.53 points, or 0.18%, to 7,710.02, while the Nasdaq Composite edged down 15.09 points, or 0.06%, to 26,348.35.
A strong earnings season had eased concerns about AI-related capital expenditures, and optimism over a potential end to the U.S.-Iran war had driven the Dow and S&P 500 to record closing highs earlier in the week. However, oil prices surged sharply on Thursday after Iran released a restrictive draft framework for Hormuz Strait shipping management, reigniting fears of disruption to global crude flows.
Under the proposed terms, Iran would ban U.S. and Israeli vessels from transiting the Strait of Hormuz. Ships from other nations that have caused harm to Iran would also be barred until reparations are completed.
"The market's reaction to macro headlines may be more muted than it used to be, partly because we're in the summer trading lull and partly because there's some Iran fatigue setting in," said Robert Bernstone, Head of New York Trading at SummitTX Capital. "To be clear, Iran's influence is fading — but it hasn't disappeared. Tweets and headlines move markets, but the details are what really matter."
According to LSEG data, as of Wednesday morning, 382 S&P 500 companies had reported earnings, with 84.8% beating analyst estimates — well above the 68% historical average since 1994.
On the economic data front, weekly initial jobless claims rose slightly. Markets are now awaiting Friday's July nonfarm payrolls report, which will be a key input for the Fed's rate path. Fed Chair Kevin Walsh has reduced forward guidance, making the data itself the primary signal for market participants.

Institutional Views
BlackRockSELECTIVE
Upgrades energy sector to Overweight following Iran's restrictive Hormuz draft. Recommends XLE and XOP as tactical hedges against geopolitical risk. Maintains selective overweight on equities overall, but flags that oil above $80 could reignite inflation expectations and delay Fed rate cuts.
UBSBULLISH
Raises S&P 500 year-end 2026 target to 8,000 on stronger-than-expected Q2 earnings season, with 85%+ beat rate. Remains Overweight U.S. equities and upgrades Asia ex-Japan to Overweight as Middle East de-escalation reduces energy cost headwinds. Expects Fed to cut rates twice in H2 2026 as oil declines ease CPI, providing additional tailwind for risk assets.
J.P. MorganCONSTRUCTIVE
Highlights energy as the key tactical trade following the Hormuz draft. Notes that Trump's polysilicon tariffs add a new layer of supply-chain risk for solar and semiconductor sectors. Maintains Overweight on U.S. equities but shifts preference toward value and energy over growth. Friday's payrolls data will determine whether the Fed can afford to stay on hold.
