Microsoft, Amazon, Alphabet, Intel, and SanDisk are set to report earnings this week, with results likely to determine the next direction for the technology sector. Eric Bleeker, Chief Investment Officer at 24/7 Wall St., identifies this as a potentially critical period for artificial intelligence stocks in 2026. Following sharp declines in AI infrastructure companies, Wall Street is questioning whether the hundreds of billions of dollars invested in data centers will generate sufficient returns. Investors are closely watching Microsoft's Azure growth and Amazon Web Services' accelerating revenue. Alphabet's expanding investments in AI infrastructure will also be a key indicator. Additionally, reports from Intel and SanDisk could provide insight into demand for semiconductors and memory. Bleeker notes that these earnings reports could either reignite enthusiasm for AI stocks or accelerate the current selloff.
