Stocks are company shares.
You will become a shareholder when you own stocks. The person/faction that owns the majority of the stocks of a faction technically owns also said faction.
But owning also just a single stock gives you insight about the faction itself.
I have just sent you one stock of Cerberus Corporation. Click on it in your stock inventory to see the additional information you can get by it.
Since this is a thread about stocks I might as well. How many stocks can a faction make when enterering the stock market? And can a faction enter the stock market at any time or only when they go faction?
