In February 2010, CME Group agreed to purchase 90% of Dow Jones & Company's financial-indexes business, including the Dow Jones Industrial Average. CME Group and Dow Jones & Company subsequently contributed the Dow Jones Indexes to the formation of S&P Dow Jones Indices, with CME Group receiving a 24.4% ownership interest and Dow Jones & Company receiving a 2.6% ownership interest in the joint venture. In April 2013, CME Group purchased the Dow Jones & Company interest for $80 million, increasing CME Group's interest in S&P Dow Jones Indices from 24.4% to 27.0%.
In December 2020, S&P DJI removed some Chinese companies from its indices following an executive order signed by President Donald Trump which prohibited U.S. investors from purchasing or investing in securities of companies which the U.S. Department of Defense has designated as being backed by the Chinese Military.
