Is stock in a company considered a good or a service, or something else?
Well it depends on whether or not your differentiating against. If its capital stock or stock as in a share certificate in the company. If its a share in the company then in my opinion using Equity would be best as it is a form of an asset and does refer to a piece of ownership of the entity. I wouldn't consider a share of stock a service, since the service to you is say Facebook or the broker who facilitates the transaction of buying or selling FB stock. I also would not consider it a Capital Good, as the Capital Good's would be the referring to the actual capital like the servers,other computer equipments etc.
