The positive momentum was further fueled by Dell's impressive earnings report, which sent the computer giant's shares skyrocketing.**Key Developments**The US-Iran crisis, which had been escalating over the past few weeks, took a dramatic turn when the US and Iran agreed to a tentative deal, brokered by European allies.

The company's success is also a reflection of its successful pivot towards higher-margin businesses, such as its cloud and security divisions.**Future Outlook**As the market looks to the week ahead, investors will be keeping a close eye on economic data, including the upcoming release of the US GDP figures. The market is also likely to be influenced by the ongoing earnings season, with several major tech companies, including Microsoft and Alphabet, set to report their quarterly results.The easing of US-Iran tensions is likely to have a positive impact on the market in the short term, as it reduces the risk of a geopolitical shock.
