The Dow Jones Industrial Average climbed Monday, buoyed by news related to U.S.-Iran relations. The broader market showed positive momentum despite geopolitical uncertainties.

SpaceX shares posted sharp gains following the company's inclusion in the Nasdaq-100 index. The move signals growing institutional recognition of the space exploration and satellite communications firm.

Specific figures on the Dow's rise and SpaceX's rally were not disclosed in available reports. The Nasdaq-100 addition is a significant milestone for SpaceX, often seen as a validation of its market standing.

Market watchers are now assessing the dual catalysts: geopolitical developments with Iran and the structural shift in index composition. The rally may face headwinds if U.S.-Iran tensions escalate.

Some analysts caution that geopolitical-driven gains can be fleeting, urging investors to focus on fundamental drivers rather than short-term news events.
