El saldo del período: cuánto dinero entra y cuánto sale
En los Formularios 4 presentados entre el 14 oct 2025 y el 10 sept 2026 no consta ni una compra en mercado abierto de Lam Research Corporation: 23 ventas por $177,4M y cero dólares comprados.
Solo cuentan los códigos P y S, donde el directivo pone o saca su propio dinero. Que el saldo de Lam Research Corporation salga vendedor es lo habitual en el S&P 500, donde buena parte del sueldo se cobra en acciones. No es una recomendación de comprar ni de vender: es lo que se declaró.

Quién ha operado
En los 15 meses del histórico han declarado operaciones de Lam Research Corporation 19 personas o entidades distintas. De ellas, ninguna compró en mercado abierto y 9 vendieron.

Cómo leer estos datos
12 de las 20 ventas de la tabla van marcadas como programadas (plan 10b5-1): se firman con meses de antelación y se ejecutan solas, así que no dicen lo que el directivo piensa hoy. Lam Research no tiene ninguna compra en mercado abierto (código P) en el histórico, que es lo más común en el S&P 500: los directivos ya cobran en acciones. La última presentación es del 10 sept 2026, y el Formulario 4 llega hasta dos días hábiles después de operar.
19 de las 20 filas de la tabla llevan notas al pie del propio Formulario 4, plegadas en la columna del código y copiadas tal cual, en inglés; una fila sin nota es que el formulario no la trae.
