On September 1, KLA Corporation fell 3.19% in regular trading, trading at $170.23/share, with turnover of $117 million. The decline came as UBS lowered its price target on KLA Corporation to $200 from $215 while maintaining a Neutral rating, adding pressure to an already weak semiconductor equipment sector.

The downgrade reflects ongoing concerns over KLA Corporation's China revenue exposure, which accounts for over 30% of total sales, amid tightening export control risks. Rising input costs have also weighed on gross margin expectations. While the company delivered strong Q4 results with revenue up 15% year-over-year to $3.66 billion — beating the $3.6 billion consensus — the stock has struggled since the earnings release in late July, when shares initially dropped over 9% on profit-taking despite the beat. Recent insider sales, including CEO Richard P. Wallace's disposal of 87,568 shares and executive Brian Lorig's sale of 59,586 shares in August, have further dampened sentiment.

Within the Semiconductor Equipment sector, broad weakness was evident. Among peers, Applied Materials fell 3.4%, Lam Research declined 3.05%, ASML Holding dropped 1.72%, Teradyne lost 4.86%, and AXT Inc slid 9.12%.
