Final answer:
A corporation with ownership limited to a small group of stockholders is a private company, which does not issue publicly traded stock and typically has ownership involved in daily operations.
Step-by-step explanation:
A corporation whose ownership is confined to a small group of stockholders is called a private company. Unlike public companies whose stock may be traded on public stock exchanges, a private company does not have publicly issued stock. Ownership is typically held by a small number of individuals who may also be involved in the day-to-day operations of the company. Instances of such private corporations include large firms like Cargill and Mars, which, despite their scale, do not offer their stock to the general public.
