¿Como se establece el índice general del Ibex 35?
 

Siempre pensé que el indice era una media ponderada de todos los valores, pero en la jornada de hoy me he dado cuenta de que una de las veces el indicativo general reflejaba una diferencia de -0,19, solo uno de los valores se situaba por debajo de ese indice "Unión Fenosa" con -017.

una característica fundamental de este índice es que se calcula de manera ponderada de acuerdo a la capitalización bursátil, lo cual se traduce en una variedad de empresas que lo integran y que no necesariamente son grandes o poderosas, sino que se evalúan simplemente por su liquidez

[url]http://www.barandilleros.com/ibex-35-algunas-consideraciones.html[/url]

has tomado los valores de invertia cuyas cotizaciones no son en tiempo real.

sabito y como es que no te tenemos en el concurso de bolsa?? :p

Marta, entre telefónica, santander. bbva e iberdrola ya representan el 59% del índice, así que sí estos no bajan mucho o suben el índice hace lo mismo; eso lo hace uno de los manipulables del mundo.

porque estoy mayor. . . :cool:

X sabito: ya tamos con lo mismo de siempre...:p

X persee: gracias por la aclaración,no estoy muy puesta en el tema,solo en la evolución de algunos valores... :)

un saludo.

besos :p
