How to Find the Top 1200 Companies

I'm just thinking in terms of the sectors and the industry dynamic that a typical searcher would look at is very fragmented industries. So classified, I guess, very small companies, it may fall below that 1200. Do you know what that number would be? I don't have a feel for specifics. The way we define sectors, we try to go very specific. We're not looking to buy anything that private equity we're buying.
