Preferred stock is stock which is given a preference over the common stock. Ordinarily, a dividend is paid on the preferred stock before any is paid on the common shares.

The par value of a share of stock is the value named in the certificate of stock.

When a corporation is prosperous, its shares of stock often sell for more than the value named in the certificate of stock. They are then said to be above par, or at a premium. In times of business depression, often these shares of stock sell below their face value. They are then said to be below par, or at a discount.

The market value of a share of stock is the value for which it sells in the open market.
