U.S. stock index futures point to a strong opening for technology shares this week, while a major South Korean memory chipmaker is set to test the sustainability of the artificial intelligence-driven market rally.

At 6:47 a.m. New York time, Nasdaq 100 futures were up 1%, S&P 500 futures gained 0.4%, and Dow Jones futures were largely flat.

Samsung Electronics Co Ltd is scheduled to report earnings on Tuesday. The chipmaker's stock has surged 165% year-to-date, making its financial performance a key focus for investors. Shortly after, SK Hynix Inc will proceed with its planned $29 billion U.S. listing.

The significance of these events is heightened this week due to a light schedule of economic data and before the U.S. earnings season fully kicks off. Recent uneven performance in global markets has led investors to question whether the AI-fueled rally of the past quarter has gone too far and whether massive capital expenditures will inevitably translate into strong returns.

In a separate development, SpaceX is set to be added to the Nasdaq 100 Index on Tuesday, a move that could prompt some index-related portfolio adjustments.

Roberto Scholtes, Chief Strategy Officer at Singular Bank, commented, "Speculative positioning in semiconductors and other hot tech themes is likely to continue being unwound. The key question is whether this triggers a rotation of funds into lagging sectors or prompts a broader market correction."
