Stock Market Midday, July 30: Microsoft Soars 15%, Boosting Tech Stocks

Microsoft jumped 15.5% in midday trading July 30 after reporting earnings that beat expectations and reinforced investor conviction in artificial intelligence spending. The move lifted the Nasdaq 2.42% as the broader tech sector recovered from prior-session losses.

The rally comes against a backdrop of weakening economic data. Second-quarter GDP growth decelerated to 1.5%, missing consensus forecasts and pointing to slowing momentum even as equity markets push higher. The contrast between MSFT's AI-driven strength and softer macro prints highlights the narrow leadership driving current gains.

Microsoft's surge single-handedly shifted sentiment in mega-cap technology, pulling the index out of the red and adding roughly $300 billion in market capitalization. The stock's performance suggests institutional buyers remain willing to pay up for companies demonstrating tangible returns on AI infrastructure investments, despite broader economic headwinds.
