Brian Szytel recaps a mixed market close on Tuesday, April 28, with tech and the NASDAQ down about 0.9% while the Dow was flat and the S&P 500 fell about 0.5%, driven by AI concerns and competition after OpenAI missed numbers amid market-share losses to Gemini and Anthropic. He notes the importance of sector divergence and warns that semiconductors alone are about 17% of the index, nearing the combined weight of several major sectors. Treasuries were flat, while oil surged (WTI up ~3.7%, Brent over 104 and WTI near 100) on ongoing Middle East tensions and the Strait of Hormuz remaining closed, potentially weighing on GDP and global growth. He addresses record margins as largely reflecting index composition shift toward higher-margin tech.
