Data compiled by Woofun AI shows that the Nasdaq Composite retreated more than 1.3% on Monday, weighed down by a broad sell-off in mega-cap technology stocks that overshadowed optimism from U.S.-Iran diplomatic progress. The decline was anchored by Alphabet, which plunged approximately 5% following news that John Jumper, Vice President of Google DeepMind and 2024 Nobel laureate, is moving to Anthropic, triggering fears of an AI talent drain.

Concurrently, SpaceX shares tumbled over 16% to establish a new all-time low.

Meanwhile, the semiconductor sector defied broader market weakness, surging roughly 2% to reach a historical high. Lam Research (LRCX) and Intel (INTC) led the rally with gains of 5.27% and 5.19%, respectively, while Applied Materials (AMAT) and KLA Corporation (KLAC) also posted solid advances. In storage, Micron Technology (MU) jumped 6.82%, and optical communication stocks saw widespread strength, with Credo (CRDO) climbing 11.29% and Coherent (COHR) rising 9.22%.
