Looking Ahead

The market remains in a tug-of-war between strong corporate earnings (especially in tech and energy) and the persistent upward pressure on long-duration Treasury yields. If the 30-year yield breaks decisively above 5.5%, expect broader equity weakness. Key catalysts to watch: upcoming Federal Reserve speakers, PCE inflation data, and Q3 earnings guidance from mega-cap tech.
