I imagine there are very few traders here with access to CRSP data due to its high cost and infrequent updates (annual at the standard subscription level and monthly at the top level), so I don't expect many (if any) responses. But I thought I'd mention that I've spent several years developing a daily update routine for personal use that scrapes data from free sources all over the internet and produces a year-to-date addendum to the most recent annual CRSP database of daily stock data. It extends all of their tables, including Price/Volume, Shares Outstanding, Delistings and Names history (identifiers, security classification, etc). New listings are immediately added to the tables throughout the year using the exact inclusion rules that CRSP uses. If this would be of interest to anyone, let me know. It would be nice to finally make a few bucks off of my obsessive-compulsiveness, so if there were enough interest in it, I might consider selling daily feeds of my CRSP addendum. I'd also consider trading it for other data instead. If either of these possibilities interests you, let me know how much you think it might be worth, in either dollars or data.
