John P. Calamos and Nick P. Calamos of money manager Calamos Investments give their thoughts on the recent market downturn and surrounding events. "Throughout July, market participants grew increasingly apprehensive about global growth and government debts. As anxieties bubbled over in early August, the see-sawing in the markets gave way to frenetic gyrations. Investors are rightly concerned about many of the issues facing the U.S. and global economies, but we continue to caution against emotion-driven reactions, whether markets are advancing or declining."
