Yields climb and markets wobble as Boston Scientific slides and Qualcomm advances

Higher U.S. Treasury yields are pressuring profits and weighing on stocks, with Boston Scientific dropping 5.9% after a cybersecurity outage foul‑up that could dent Q3 and full‑year 2026 forecasts, and Novartis tumbling 13.9% on a disappointing therapy study. Qualcomm rose 3.2% after announcing a large‑scale AI data‑center collaboration with Amazon. Overseas, Japan’s Nikkei fell about 1.7% as exporters fret the stronger yen ahead of a Bank of Japan meeting, while China’s exports jumped 25% year‑over‑year in August; the day underscores a global market mix of growth signals, currency moves, and central‑bank expectations.
