Link any type of identifier (ticker, CUSIP, PERMNO, etc.) to GVKEY and one another.By using WRDS tools, researches can easily perform the following operations: WRDS offers just such tools of commonly used link resources. To ensure that the data from different datasets applies to the same company, researchers need tools to convert permanent identifiers from one to another or to link data from different datasets for the same companies. CRISP is maintained by Chicago Booth CRSP, and Compustat by S&P. GVKEY (Global Company Key) is a unique number assigned to each company in the Compustat-Capital IQ database.ĭifferent datasets in WRDS are collected from different sources, e.g.
On Decemthe closing price of shares with PERMNO 75104 was $42.440 and shares with PERMNO 76226 closed at $42.020. While most of the companies have one class shares, some companies have more than one class shares traded at different prices, and this is the reason why a company can have more than one PERMNOs.įor example, CBS Corporation (CBS) has two classes of shares (at the time of publishing of this document), and respectively two PERMNOs. PERMNO is a unique stock (share class) level identifier.in 1946, then changes to Consolidated Foods Corp.(CFD) in 1954, then became Sara Lee (SLE) in 1985, and as of 2012 is called Hillshire Brands Co. PERMCO is a unique company level identifier that remains unchanged throughout the whole term of company’s existence even if the company changed name/s.įor example, the PERMCO 21566 stays unchanged through the whole history of the company that started with the name Consolidated Grocers Corp.PERMCO and PERMNO are unique permanent identification numbers assigned by CRSP to all companies listed in CRSP dataset. For historical analysis on securities, researchers use permanent identifiers, such as PERMNO, PERMCO, and GVKEY that never change for the duration of the company’s life span regardless of the name changes or other instances and are never being reused.
