Intel Stock Soared About 278% in the First Half of 2026, Then Fell 10% in a Single Day. Buy the Dip or Run for the Hills?

Intel surged 278% in the first half of 2026 under CEO Lip-Bu Tan, driven by successful adoption of its 18A manufacturing process and major foundry wins from Tesla and Apple. The rally reversed sharply in July with a 10% single-day drop, raising questions about whether the stock has overshot fundamentals.

The chip giant's turnaround hinges on its foundry business, which secured high-profile customers including Tesla and Apple for chips built on the advanced 18A node. That momentum propelled shares to triple-digit gains in six months, rewarding investors who bet on Tan's restructuring strategy.

Valuation now presents a challenge. Intel trades at a forward price-to-earnings ratio between 89 and 127, according to analysts, while revenue growth is projected at just 7%. The disconnect between price and near-term earnings has prompted analyst caution, with recommendations shifting to hold rather than buy. The consensus view: the stock is pricing in multiple years of growth that hasn't yet materialized.

The July selloff suggests profit-taking as momentum traders exit positions built during the first-half surge.
