1. On September 18, 2026, Apple launched its new smartphone and continued its in-house chip strategy; Qualcomm expects its modem market share to decline, and the agreement renewed on September 24 covers only patent licensing, not baseband supply, meaning long-term pressure on chip revenue.
2. On September 28, 2026, the 30-year US Treasury yield rose to 5.54%, reaching its highest level since May 2004. The high interest rate environment puts valuation pressure on technology and semiconductor stocks.
3. On September 21, 2026, Qualcomm's stock price surged 9% in a single day; as of September 27, the stock price was close to a recent high. After expectations for the Snapdragon Summit, artificial intelligence, and data centers were priced in, technical pullback pressure emerged.
