This classification of stock allows you to vote in corporate matters.

Common stock is a classification of stock that typically grants shareholders the right to vote on corporate matters, including the election of the board of directors and other significant company decisions. This voting power is a hallmark of common stock, giving shareholders a voice in the management and strategic direction of the company.

In contrast, preferred stock usually does not come with voting rights, as it is designed for investors seeking fixed dividends and less volatility, focusing more on income stability rather than control. Treasury stock refers to shares that were once part of the outstanding shares but have been repurchased by the company, and stock options are contracts that give the right to purchase shares at a predetermined price in the future, rather than being a form of stock itself.

Understanding these distinctions highlights why common stock is the correct answer when it comes to voting privileges in corporate governance.
