Astera Labs, Inc. (ALAB) saw its stock price plummet 6.91% during intraday trading on Monday, extending recent losses for the semiconductor connectivity company.

The sharp decline was driven by a broad selloff across the optical communication and semiconductor sectors. Peer companies including Applied Optoelectronics, Lumentum Holdings, Credo Technology, Fabrinet, and Coherent all experienced significant drops of more than 5%, with Applied Optoelectronics falling over 10% and Lumentum Holdings declining nearly 8%. This sector-wide weakness dragged Astera Labs lower in sympathy with the broader industry trend.

Additionally, the stock had already been facing selling pressure in prior sessions due to ongoing semiconductor sector weakness and reports of insider selling activity, which amplified the downside momentum during Monday's trading session.
