Is Zakat obligatory on saved portfolio shares if the company pays Zakat to the government on all its assets?

The distribution of zakat on hidden wealth, such as trade goods, is left to their owners according to the majority of scholars. If the ruler undertakes its collection and distribution, it suffices, and the owner's responsibility is discharged. Zakat is not valid without the owner's intention, based on the Prophet's (peace be upon him) saying: "Indeed, actions are by intentions." It is permissible for a company to be authorized to pay zakat to the government. The determination of the zakat base (assets or profits) varies depending on the type of shares and the owner's intention behind them.
