The Nasdaq Composite Index (COMP:IND) experienced its third consecutive weekly decline, closing down 0.93% on Friday, as tech stocks faced headwinds amid rising tensions between the U.S. and Iran. The index's performance was significantly impacted by the broader market sentiment surrounding the geopolitical conflict, which has created uncertainty for investors and contributed to the Nasdaq's recent struggles.

Micron Technology emerged as the week's biggest gainer, likely driven by anticipation surrounding its upcoming earnings report. Investors are closely watching Micron's results as a key indicator of the overall health of the semiconductor industry and the broader tech sector. The company's performance often influences other tech stocks, making it a crucial player in the market. As the tech sector continues to navigate the challenges posed by the US-Iran conflict, Micron's earnings report will be closely watched for any signs of weakness or strength.

Conversely, Thomson Reuters recorded the largest loss among companies within the Nasdaq Composite. Specific details regarding the reasons for Thomson Reuters' decline were not immediately available, but market analysts suggest it could be related to broader industry trends or company-specific factors. Further investigation is needed to determine the exact cause of the stock's underperformance. The escalating US-Iran conflict continues to be a significant factor impacting market volatility, and its impact on the tech sector will be closely monitored in the coming weeks.
