Corporations can be sold to investors through stocks or shares, as a public entity. Thus, a company that engages in the sales of ownership shares to many investors is referred to as a corporation.

The book value per share of stock can be defined as a measure of the total amount of value associated with a net asset that an investor is entitled to when he or she buys a share of stock.

Hence, the book value per share of stock is a ratio of the equity gotten by an investor to the amount of outstanding shares.
