Nasdaq up 0.5% on softer inflation, AI stock earnings beat

Today's session reflects the interplay between macroeconomic data and sector-specific momentum. The softer inflation reading, which aligned with market expectations, removed a source of near-term uncertainty around monetary policy and interest rates—critical for equity valuations, particularly in growth-heavy sectors like technology and AI. Against the backdrop of what the article describes as an otherwise quiet trading environment, earnings beats from Super Micro Computer and Lumentum provided concrete evidence that AI-related companies are delivering results, reinforcing the narrative that supports continued investor appetite for the sector. The modest 0.5% gain on the Nasdaq, combined with the characterization of the session as "fairly uneventful," suggests that while these positive signals supported prices, there was limited broad-based enthusiasm or fresh catalysts driving aggressive buying.
