On August 3, KLA Corporation fell 3.91% in regular trading, trading at $176.14/share, with turnover of $194 million. The decline came amid a broad global semiconductor sector selloff that terminated the stock's post-earnings rebound momentum.

On the news front, the Korean KOSPI index plunged over 5% triggering a circuit breaker mechanism, with Samsung Electronics and SK Hynix both closing down more than 8%, placing heavy pressure on semiconductor equipment names globally. Short-term profit-taking intensified as gains accumulated during the July 30-31 rebound of over 12% were unwound. Within the Semiconductor Equipment sector, Lam Research fell 4.02%, Applied Materials declined 2.62%, Teradyne dropped 2.62%, AXT Inc lost 1.24%, and ASML Holding fell 0.99%.

KLA had previously reported record fourth fiscal quarter revenue of $3.66 billion, up 15% year-over-year, with adjusted EPS of $1.05 beating estimates by 5%. Despite the strong results, the stock initially fell over 9% on profit-taking given its 57% year-to-date gain, then staged a technical rebound before this latest wave of sector-wide selling pressure.
