Shareholder(redirected from Stock holder)
Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.
If you own stock in a corporation, you are a shareholder of that corporation.
You're considered a majority shareholder if you alone or in combination with other shareholders own more than half the company's outstanding shares, which allows you to control the outcome of a corporate vote. Otherwise, you are considered a minority shareholder.
In practice, however, it is possible to gain control by owning less than 51% of the shares, especially if there are a large number of shareholders or you own shares that carry extra voting power.
