Largecap News Today — August 28, 2026

US markets are likely to be influenced by a mix of corporate updates and global events as investors await remarks from the Federal Reserve chair at Jackson Hole. The performance of major stocks has been varied, with Salesforce experiencing a significant surge of 20%, providing a boost to the software sector. Other companies, such as Marvell, have revised their forecasts upward, but this hasn't translated to a notable increase in its stock value. Meanwhile, SK Hynix is making substantial investments in the US, planning to establish a key memory production base in Indiana by 2030.

In other news, global developments are also making headlines. The situation in Iran remains tense, with the country linking the reopening of the Hormuz Strait to an end to regional conflicts, while reports suggest that US President Trump is unlikely to agree to a return to the June deal. On a more personal note, a dispute over a $42,000 pool upgrade has raised questions about homeowners' rights when contractors subcontract work to previously rejected vendors. As investors assess these diverse factors, they will be closely watching the Fed chair's speech at Jackson Hole for insights into potential monetary policy shifts and their impact on the market.
