Taken together — from the beginning of 2009's trading through yesterday's final 2011 session — The Dow is up 39.21%.

McDonald's, IBM and Pfizer all gained more than 20% this year.

IBM Corp. (up 25.29%) and Pfizer Inc. (23.59%) closed 2011 as the Dow's second- and third-leading performers, respectively.
