Stocks initially found support on Monday amid strength in technology stocks after stellar revenue growth at Anthropic PBC bolstered the view that spending on artificial intelligence will be sustained. Anthropic told prospective investors that its Q2 revenue jumped by at least 14-fold from the same period last year, according to a report today by Bloomberg. However, the weakness in software stocks is weighing on the Dow Jones Industrial Average.
Stocks also found support on some better-than-expected US economic news. The Aug Empire manufacturing survey general business conditions index unexpectedly rose +5.0 to a 4.5-year high of 20.6, stronger than expectations of a decline to 10.0. Also, the Aug NAHB housing market index unexpectedly rose +1 to 35, stronger than expectations of a decline to 33.
Signs of weakness in China’s economy undercut global growth prospects and were negative for stocks. China's July industrial production rose +4.5% y/y, weaker than expectations of +5.0% y/y. Also, China's July retail sales rose +0.6% y/y, weaker than expectations of +1.5% y/y. In addition, the China July survey jobless rate rose +0.2 to 5.2%, showing a weaker labor market than expectations of 5.1%. Finally, China's July new home prices fell -0.18% m/m, the thirty-eighth consecutive month home prices have declined.
Sep WTI crude oil prices (CLU26) rallied more than +2% on Monday to a 3-week high amid fresh Israeli attacks on Iran-backed Hezbollah in Lebanon, dampening the prospects of ending hostilities in the Middle East and a quick reopening of the Strait of Hormuz. Also, Israel has struck Iran-backed Hamas in Gaza, the Yemen- based Houthis have attacked ships in the Red Sea, and several vessels have been hit by projectiles in the Strait of Hormuz. President Trump said today that the US naval blockade on Iranian ports is putting pressure on the country, and he has no timeline for resolving the US-Iran conflict.
Crude prices raced to their high on Monday after US Energy Secretary Chris Wright said that the US is playing the long game with Iran, implying the US has no plans for de-escalation of the conflict, potentially limiting crude supplied from the Middle East.
Iran and Oman appear to be edging closer to a deal on how the Strait of Hormuz should be managed, agreeing on routes through the waterway. Iranian Foreign Ministry spokesman Baghaei said on Monday that finalizing a "shipping map" is part of a broader accord to govern traffic through the strait and constitutes an independent arrangement between the two states that will uphold their sovereignty and ensure the safe transit of vessels.
Treasury Secretary Bessent said last week that the administration will soon announce unprecedented economic measures against Iran that “have never been seen in the history of economic isolation of a country.” The economic measures would add to the current US naval blockade of Iranian ports.
There have been no signs of progress toward a US-Iran agreement to fully open the Strait of Hormuz. An Iranian military spokesperson said last Thursday that no ship can safely pass the Strait of Hormuz without Iran’s authorization and supervision and that President Trump’s claims of control over the Strait are “nothing more than lies.” The Iranian statement was in response to President Trump's comment last Tuesday that the US has “total control over the Hormuz Strait” and that “we own it.”
The outlook for strong Q2 earnings is a bullish factor for stocks. The S&P 500 is tracking for earnings growth of almost 32% in Q2, well above projections of +23%, and nearly four times the average earnings growth rate outside of the Covid period since Q4 of 2013, according to Bloomberg Intelligence. AI spending is expected to account for most of earnings, with AI infrastructure stocks set to contribute nearly 60% of the S&P 500's earnings-per-share growth in Q2. So far, earnings results have been positive, with 85% of the 456 S&P 500 companies that have reported Q2 earnings beating estimates, according to Bloomberg data.

The 10-year breakeven inflation rate rose to a 3-week high of 2.296% on Monday. Also, Monday’s stronger-than-expected US economic news on the Aug Empire manufacturing index and Aug NAHB housing market index weighed on T-note prices.
