Callan's Periodic Table of Investment Returns

"The first Callan Periodic Table of Investment Returns was published (and copyrighted) by Callan Associates, Inc. in 1999. The Table is updated each year and can be found (free of charge) on Callan's website. As the proud father of Callan's Periodic Table of Investment Returns, and the coiner of the name, I am happy to see it adopted by many in the investment industry, all we ask is for acknowledgment."
