KLA Corporation fell over 3% alongside peers including Lam Research, Intel, and Teradyne during regular trading on September 23.

Adding to sentiment headwinds, KLA Corporation director and executive Richard P. Wallace recently filed a Form 144 restricted stock sale notice, disclosing plans to sell 72,019 shares valued at approximately $12.38 million. Wallace had previously sold 87,568 shares at $198.95 on August 11 through a 10b5-1 trading plan. Consecutive insider dispositions at the executive level have weighed on market confidence.
