US stocks close mostly lower in a mixed session as investors respond to remarks by President Donald Trump about an interim deal related to ending the conflict involving Iran. Reports say Trump stated the interim agreement is “over,” prompting market participants to reassess expectations for de-escalation between the United States and Iran. The S&P 500 ends lower overall, reflecting investor caution amid uncertainty around the status of any truce or negotiation. In contrast, some areas of the market gain: Broadcom is cited as leading advances among recently battered chip stocks. Other chip-related equities also recover from prior declines, suggesting investors are selectively buying specific sectors even as broader risk sentiment remains subdued. Overall, the session reflects a split between concerns tied to geopolitical developments and pockets of strength in technology and semiconductors.
