Nasdaq-100 futures plunged over 2% in pre-market trading, signaling a significant downturn for the technology sector. The sell-off was primarily triggered by disappointing quarterly earnings reports from mega-cap tech companies Amazon and Intel, which missed market expectations. This follows a recent negative trend in the tech sector, which was already under pressure after Alphabet's underwhelming earnings report. The weak results from these major tech players are raising concerns about a slowdown in the industry.
