Stock discount is the opposite of stock premium. Discount occurs when the selling price of shares is lower than their nominal value. For example, if shares are sold for Rp3,000, while the nominal value is Rp5,000, then the difference of Rp2,000 is called stock discount.
Stock discount usually occurs in companies that are forced to expand even though their financial condition is unstable, even at a loss. Therefore, the company is unable to sell shares at a price higher than their nominal value.
