To match equities from databases (CRSP, Compustat, Datastream, Execucomp, NYSE TAQ, SDC), see the Matching Guide. For hints on finding specific items in these databases as well as additional sources, see the Economics and Finance FAQ.
- CRSP DEMO
- Reports prices as they were traded (not adjusted for splits). Holding returns are adjusted however. To adjust prices for a long time series comparison, the best variable to use is the cumulative factor (query item: CFAPR-- Cumulative Factor to Adjust Price) that WRDS computes from the factors CRSP provides for a particular trading day or month. Use this formula: PRC_SPLITADJ = PRC/ CFACPR
Dividends can be adjusted the same way. For shares, use CFACSHR as the cumulative factor. (In most cases, the two cumulative factors are the same, but not always.)
- For the latest data, see quarterly updates at the bottom of the CRSP screen.
- Prc is the closing price or the negative bid/ask average for a trading day. If the closing price is not available on any given trading day, the number in the price field has a negative sign to indicate that it is a bid/ask average and not an actual closing price. Please note that in this field the negative sign is a symbol and that the value of the bid/ask average is not negative.
- Use the Linking Suite to link CRSP stocks to corporate bonds in TRACE, options in Optionmetrics, earnings forecasts in IBES, or intraday data in TAQ.

Fama-French Research Portfolios and Factors. Constructed from the intersections of 2 portfolios formed on size, as measured by market equity (ME), and 3 portfolios using the ratio of book equity to market equity (BE/ME) as a proxy for value. Returns from these portfolios are used to construct the Fama-French Factors. Eugene Fama and Kenneth French showed that their factors capture a statistically significant fraction of the variation in stock returns (see "Common Risk Factors in the Returns on Stocks and Bonds", Journal of Financial Economics 33, 1993). Source is Kenneth French's web site at Dartmouth. Available on WRDS.
When needing the original, unadjusted prices of stocks the following sources from Standard & Poor's are useful:

|Daily Stock Price Record. American Stock Exchange||1962-2003||HG4915.I22|

NYSE TAQ**: Tick data for equities traded on the New York Stock Exchange, American Stock Exchange, and NASDAQ. Data time stamped by the second for 1993-2014 is available through WRDS (see Section I).

Additional data for the NYSE and AMEX is available for 1983-1992 and for the NASDAQ for 1987-1992 through ISSM which is also found on WRDS. Due to the size of files, using SAS is often the best option (see sample extraction programs). To link to CRSP use the TAQ CRSP link.

|Russell Index Constituents*||Constituent lists for the Russell indexes with weights back to 1979. Limited data back to 1978.|
|S&P 500 Constituents** (accessed through CRSP on WRDS)||CRSP created a PERMNO-based historical list of S&P 500 constituents as part of their Indices product. Can be extracted using the CRSPAccess stk_print utility (using the /g16 option, see the CRSPAccess manual for details). A SAS dataset can be found at /wrds/crsp/sasdata/msp500list.sas7bdat. The daily SP500 version is dsp500list. (The S&P 500 started later as a daily published index. It has the same members as the monthly for the overlapping date range, and for most purposes the dsp500list can be safely ignored even if you are interested in daily data.) This list does not show exactly 500 members at any point in time. The index had only 90 members until March 1957 and S&P does not always remove a delisted security from the list immediately. For more detail on the CRSP S&P 500 members list, see the CRSP Data Definitions Guide in CRSP Index Methodologies under "CRSP Indices for the S&P Universe".|
