O meaning in Stock Exchange ?

Ownership is the state or fact of exclusive rights and control over property, which may be any asset, including an object, land or real estate, intellectual property, or until the nineteenth century, human beings. Ownership involves multiple rights, collectively referred to as title, which may be separated and held by different parties.

The process and mechanics of ownership are fairly complex: one can gain, transfer, and lose ownership of property in a number of ways. To acquire property one can purchase it with money, trade it for other property, win it in a bet, receive it as a gift, inherit it, find it, receive it as damages, earn it by doing work or performing services, make it, or homestead it. One can transfer or lose ownership of property by selling it for money, exchanging it for other property, giving it as a gift, misplacing it, or having it stripped from one's ownership through legal means such as eviction, foreclosure, seizure, or taking. Ownership is self-propagating in that the owner of any property will also own the economic benefits of that property.
