Whalewisdom.com has rolled out an improved filer search at http://whalewisdom.com/search/advanced_filer_search.

Improvements include:

• the ability to drilldown by certain types of filers:
  • 13F filers
  • management investment companies
  • open-end investment companies
  • closed-end investment companies
• Filter by one or more states
• Filter by a total market value range based on the filer’s last 13F holdings report
• Filter by the total number of holdings included in the last 13F holdings report
• Filter by the last 13F quarter a filer submitted a 13F
• Find all filers that have a certain concentration percentage of top 10 holdings by market value
• An overall increase in search speed and responsiveness

There’s a lot of data in the Whalewisdom database that can be mined.  Feel free to suggest any other attributes you would like to be able to search on.  I’ve recently started processing N-SAR forms so now there’s even more data we can mine.  I just need some ideas on what you want to see.
