2012 has been a very good year for a lot of Illinois-based companies.
Crain’s Chicago Business tracks the performance of publicly-traded Illinois firms through its “Chicago Index,” measuring the performance of more than 140 companies. This year, the Illinois firms saw an increase of more than 11-percent in their stock prices over last year.
Some of the best performers were the housing-materials supplier USG, OfficeMax, and the parent company of Fisher Nuts. Illinois companies that saw declines this year include Groupon… a company promoting web-based deals… and McDonald’s, which saw its stock price drop more than 11-percent.
