US index futures were little changed on Thursday after the S&P 500 and Nasdaq Composite closed at fresh record highs in the previous session, lifted by strong corporate earnings and an extension of the US–Iran ceasefire. President Donald Trump said the current truce would remain in place indefinitely as Washington awaits a new peace proposal from Iran, although Tehran has signaled it does not intend to enter negotiations in the near term.
On Wednesday, the S&P 500 and Nasdaq Composite rose 1.05% and 1.64%, respectively, while the Dow added 0.69%. Market sentiment has been underpinned by a robust earnings season, with three out of four S&P 500 companies reporting so far beating either earnings or revenue estimates.
In extended trading, Tesla was volatile after warning of a sharp increase in capital expenditures, while IBM and ServiceNow fell more than 7% and 12%, respectively, following weaker-than-expected results.
