For example, the following chart examines reported price differences between CRSP and COMPUSTAT for IBM on an annual basis between 1950-1998. CRSP data extracted with ts_print. Graph created in Excel.

69. Software: dsxport/msxport dsxport and msxport are command line portfolio- building programs. dsxport is used with the daily data, msxport, with the monthly data. These programs require a user-created input file containing a list of CUSIPs (8-characters, without the electronic check digit), historical CUSIPs, or PERMNOs to be included in the portfolio. (CUSIP is the default.) This input file can be created in a text editor. The program prompts for input. Output is written to a log file.
