Which of the following is an example of a type of stock?

Common stock is a type of stock that represents ownership in a company and comes with certain rights, such as voting at shareholder meetings and receiving dividends. Investors in common stock have the potential to benefit from the company's growth through price appreciation of their shares, as well as from dividend payments, making it a foundational element of equity investment.

Penny stock, although a type of stock, refers specifically to shares of small companies that trade at low prices, typically below $5 a share. While it falls under the broader category of stocks, it is more of a descriptor for a specific market segment rather than a general type of stock like common stock.

Municipal stock is not a category of stock but rather refers to debt securities issued by local government entities, which are used to fund public projects. This type of investment is generally categorized under bonds rather than stocks.

Equity stock is a broader term that can encompass several types of stocks, including common and preferred stock. However, since the question asks for a specific example of a type of stock, "common stock" is the more precise answer.
