Published on 07/04/2026 08:54 PM

Stock losses picked up on Tuesday morning following President Trump’s latest threats against Iran, which raised concerns that a potential off-ramp to the hostilities may be closing.

Apple shares slid 3.4% on Tuesday after a Nikkei Asia report said the company is facing engineering setbacks in the foldable iPhone’s testing phase, raising the risk of delays to production and shipments, according to people familiar with the matter. The report said the engineering challenges are proving more complex and time‑consuming than Apple initially expected, potentially pushing the first shipment back by several months. The development comes after Apple stock had gained nearly 5% over the previous four sessions. The foldable device is expected to feature an iPad‑like interface when fully opened, Bloomberg reported earlier.

Uncertainty around the escalating US-Iran conflict has prompted UBS to turn more cautious on US equities, cutting its year‑end target for the S&P 500, CNBC reported. In a Tuesday note, the bank lowered its 2026 target to 7,500 from 7,700, though this still implies a headline gain of over 13% from current levels and a return of about 9.5% in 2026. UBS CIO Ulrike Hoffmann‑Burchardi said markets are closely watching President Donald Trump’s deadline for Iran, advising investors to de‑risk amid elevated energy prices. UBS flagged higher vulnerability in regions sensitive to energy supply disruptions, including Europe and India, while cautioning against exiting risk assets entirely given medium‑term upside potential.

Buyers are “paying an exceptional premium for secure, refinery-usable Atlantic Basin barrels available now,” analysts including Martijn Rats said in a note dated April 7. “That does not mean the futures market is broken. It just means that different parts of the complex are pricing different combinations of immediacy, tightness and expected persistence,” they added.
