Industry list

Hi Drbob-

I was just looking for the same thing. In the SIPRO Help section/Contents and Index/Industries/Industry by Code, I found the attached. Sector seem to be by name only.

I want to test a sector switching model. It looks like I will have to run the backtester for a given sector, find the strongest one in a given month, and then run the screener again for that particular sector only. That is, test for the stocks that are from the strongest sector from the time period before.

Any ideas on another way to do this?
