What financial instrument typically represents ownership in a company?

The financial instrument that typically represents ownership in a company is stock. When an individual buys stock, they are purchasing shares, which represent a fractional ownership in that company. Shareholders have the potential to benefit from the company's growth through appreciation in the stock's market value and may also receive dividends, which are a portion of the company's profits distributed to shareholders.

In contrast, bonds represent debt, indicating that the investor is lending money to the company or government for a set period and receiving interest over time. Options are contracts that grant the right, but not the obligation, to buy or sell a stock at a specified price within a designated time frame; they do not represent ownership in a company. Mutual funds are investment vehicles that pool money from multiple investors to purchase a diversified portfolio of stocks, bonds, or other securities; while they can hold stock, they do not represent direct ownership in the companies making up the fund. Thus, stock is the clear answer when discussing instruments that confer ownership in a company.
