The Dow Jones industrial average dropped 611 points, or 3.4%, to 17,399 in heavy trading Friday. The Standard & Poor's 500 index fell 75 points, or 3.6%, to 2,037. The Nasdaq composite sank 202 points, or 4.1%, to 4,707. It was the biggest drop for the Dow and S&P 500 since August and the worst fall for the Nasdaq since 2011. Some European markets fell even more. France's benchmark index lost 8% and Germany's fell 7%. Britain's fell 3%. Bond prices rose sharply as investors sought safety. The yield on the 10-year Treasury note dropped to 1.57% from 1.75% a day earlier, a huge move.
