El saldo del período: cuánto dinero entra y cuánto sale
En los Formularios 4 presentados entre el 19 dic 2025 y el 5 ago 2026 no consta ni una venta en mercado abierto de W. R. Berkley Corporation: 50 compras por $705,5M y cero dólares vendidos.
Solo cuentan los códigos P y S, donde el directivo pone o saca su propio dinero. Que el saldo de W. R. Berkley Corporation salga comprador es lo menos frecuente en el S&P 500: sus directivos ya cobran en acciones y aun así ponen dinero propio. No es una recomendación de comprar ni de vender: es lo que se declaró.

Cómo leer estos datos
Las 50 compras en mercado abierto (código P) de W. R. Berkley son la señal rara: los directivos ya cobran en acciones, y comprar más es poner dinero propio. La última presentación es del 5 ago 2026, y el Formulario 4 llega hasta dos días hábiles después de operar.
20 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.

- Qué dice y qué NO dice la hipótesis de eficienciaSi la compra de un directivo es pública y cualquiera puede leerla, ¿queda información dentro? Es la pregunta exacta que trae a esta página.
- Quién mueve realmente el mercado: los tipos de inversoresQuién hay al otro lado de cada orden, y qué sitio ocupan entre ellos los directivos de la propia empresa.
- Oferta, demanda y el precio: por qué sube y baja constantementeCómo acaba una noticia metida en el precio, y por qué la reacción a una venta declarada rara vez es la que uno esperaría.
