Shares/Stock Sites that let you keep track of all stocks you invest in ?

[greenieS]

Hello,

Do you work with any specific application where you track all your stock investments? As a portfolio or a total presentation of investments?

For example, as it is a curve card, several cards in one application from where you can control everything. That's what I mean by stocks here.

I heard from someone that a Yahoo Finance application would solve all these things and is useful for investors, but I want to hear other opinions.
