Final answer:
The market value per share is the appropriate term for the price at which a stock is traded on the stock market. This value changes based on a variety of factors and is different from intrinsic, book, and par values.
Step-by-step explanation:
The value per share that represents the price at which a stock is bought and sold is the market value per share. The market value is determined by the price that buyers are willing to pay and sellers are willing to accept in the open market. This price fluctuates constantly during trading hours due to numerous factors including company performance, investor sentiment, and external economic conditions.
In contrast, the intrinsic value is a theoretical value that represents what investors believe a stock is actually worth based on its financials and growth prospects. The book value refers to the value of a company as recorded in its books, and the par value is the face value of a stock or bond as stated by the issuer.
