On August 3, KLA Corporation fell 3.02% in pre-market trading, trading at $177.31/share, with turnover of approximately $2.79 million. The decline came as a broad-based selloff across the global semiconductor equipment sector interrupted the stock's post-earnings rebound momentum.

The sector-wide pressure was evident across major peers, with Applied Materials down 2.83%, Lam Research down 3.42%, ASML down 0.91%, AXT Inc down 5.91%, and Teradyne down 3.54%. The Philadelphia Semiconductor Index also moved lower in pre-market trading, with Micron and Lam Research leading declines. The global semiconductor sector experienced sharp adjustments, with Korean chipmakers Samsung Electronics and SK Hynix falling over 8%, triggering circuit breaker mechanisms in Korea's KOSDAQ market.

KLA had been recovering from a post-earnings selloff on July 29, when shares dropped over 9% despite reporting record Q4 revenue of $3.66 billion (up 15% YoY) and adjusted EPS of $1.05 beating estimates by 5%. Multiple analysts had subsequently raised price targets, with Argus lifting to $225 and JPMorgan to $238, fueling a multi-day rebound that has now stalled amid the broader sector weakness.
