Apple shares traded in a volatile range near $310–$327 during the week of September 7, 2026, before surging above $330 on September 10–11 amid heavy volume. The primary catalyst was the September 9 iPhone 18 launch event, which introduced the iPhone 18 Pro lineup starting at $1,199 and Apple’s first foldable device (iPhone Duo) at $1,999 under new CEO John Ternus. The initial market reaction was muted, with shares closing down modestly on launch day, reflecting already-discounted expectations and concerns over premium pricing. Strong Q3 results (16% revenue growth, record iPhone and Mac sales) and the company’s $4.85–4.9 trillion market capitalization provided underlying support, while analyst price targets around $324 and the October 29 earnings date remain key forward reference points for positioning.
