Is zakat obligatory on dormant shares acquired through subscription?

Zakat is obligatory on shares based on their type. There are previous fatwas that clarify the types of shares on which zakat is obligatory, either on their value and profit, or only on their dividends. If the shares are of a type on which zakat is obligatory on both their principal and profit, then zakat becomes obligatory on them even if they are stagnant, as long as their value reaches the nisab and a full year has passed over them.
