How do common shares and preferred shares differ?

Common shares are ordinary voting shares, while preferred shares usually carry no voting rights but rank ahead of common shares in matters such as dividends.

In the Korean stock market, preferred shares are identified by the Korean character for 'preferred' added after the stock name, and an added 'B' denotes new-type preferred shares issued with a maturity since 1996. Preferred shares have a small float, so their prices can swing widely, and they may be delisted if trading volume or the number of shareholders is too low.
