Ticker Symbol - Header is set to the first seven characters of Trading Symbol - Header for active issues, and is blank for delisted issues. The Trading Symbol - Header contains the symbol used by automated trading systems, including all supplied class, share type, or status suffixes, with no punctuation for active securities in the file. There are no current trading symbols longer than seven characters.
Ticker Symbol - Header is used in CRSP access routines and utility programs using ticker as a database key. Usage is unchanged, but input lists built on previous conventions of TICKER.SHRCLS for NYSE and NYSE American securities must be changed to comply with the new data. This change provides a field in the CRSP database that contains an exact match with symbols available directly from exchanges and other sources.
Ticker Symbol is an alphabetic symbol assigned to each security by an exchange.
Tickers can be reused over time. The combination of Ticker Symbol, Share Class, Exchange Code, and Calendar Trading Date uniquely identifies a security. A ticker may be one to three characters for NYSE and NYSE American securities or four to five characters for NASDAQ securities.
NASDAQ trading tickers have four base characters and may include a fifth character suffix that provides information about an issue's type or temporary information about an issue's status. CRSP only includes the suffix when it provides permanent descriptive information. The following table describes the suffixes appearing on the CRSP file:
Suffix
Definition
A
Class A
B
Class B
S
Shares of Beneficial Interest
U
Unit
W
When-issued
Y
ADR
Z
Miscellaneous common issues
Occasionally NASDAQ will add two additional suffixes to the base ticker to identify certain issues. However, because the NASDAQ ticker field only allows for five characters, one letter of the base ticker will be dropped. For example:
If a foreign company with a class A stock has a base ticker symbol ABCD, NASDAQ adds two additional characters, A and F. Due to NASDAQ's limited fields, they will delete a letter from the base ticker, so ABCDAF would be truncated to ABCAF.
There is no guarantee that the ticker suffix matches a share type. The Share Code variable should be used to determine the security's share type.
NASDAQ tickers before 1982 in an issue's name history are presumed to represent legitimate trading symbols for that issue at some point in time, although these symbols may be listed out of proper chronological sequence. In addition, the NASDAQ file ticker symbols provided do not necessarily constitute a definitive list of all symbols used throughout an issue's trading history. Due to source limitations, the ticker field may be blank in name histories of NASDAQ securities that stopped trading from the early 1970s through the early 1980s.

One-character field describing the status of a security most recently known at the end of the period. (A = active, H = halted, S = suspended, X = unknown)
