Cantillon Research · The Cantillon File

Stock research that follows the money

Each File takes one US stock and follows its money from the first dollar of sales to what is left for shareholders, asks what growth today's price is assuming, and checks whether institutional money is flowing in on the IVT terminal. Every number comes from SEC filings and market data. There are no buy or sell ratings.

Grouped by business quality: a score from the filings alone, with each rule printed on the File. It says nothing about the price, so a high-quality File is not a buy and a low one is not a sell.
