AMC XDVDA refers to a stock ticker symbol for AMC Networks Inc. Class D convertible preferred stock. It is a type of hybrid security that combines features of both common stock and bonds. These preferred shares have some of the characteristics of common stocks, such as the potential to earn dividends, but also have fixed, preferential dividend payments and a maturity date, making them more like bonds. The "D" in the ticker symbol represents the fact that these shares have limited voting rights compared to the company's Class A and Class B common shares. The "XD" part of the ticker stands for "extended dividend" which indicates that these shares receive dividends that are both variably and cumulatively accrued.
