R

Fifth letter of a Nasdaq stock symbol specifying that the stock has rights.

R

A symbol appearing next to a stock listed on NASDAQ indicating that the share being traded comes with a right. All NASDAQ listings use a four letter abbreviation; if an R follows the abbreviation this indicates that the share has rights attached to it.

1. Used in the dividend column of stock transaction tables in newspapers to indicate the amount of dividends declared or paid in the preceding 12 months plus a stock dividend: PE Cp .25r.
2. Used in mutual fund transaction tables in newspapers to indicate funds that levy a deferred sales charge when shares are sold: IDS Inc r.
3. Used in bond transaction tables in newspapers to indicate a registered security. Although most bonds are registered, this symbol is used when a distinction is necessary, as when a bond trades in registered and in bearer form: NoPac 3.47r.
