The CME Group will launch individual stock futures on Monday, allowing investors to hedge or speculate on more than 50 leading U.S. stocks. The contracts will be cash-settled at the closing price of the underlying stock and offer a simpler leverage option than options. The individual stock futures will trade five days a week, 23 hours a day, and will be available in two sizes: a large contract based on 100 shares and a micro contract based on 10 shares.
