Investors may have been disturbed by the rising tensions between the United States and North Korea last week, resulting in a shift from stocks to long-term bonds. The Dow, which had surged to a new record high the prior week, sunk over 1.0% last week, while the large-cap S&P 500 fell almost 1.5% following some less than stellar second-quarter corporate earnings reports. Once again, the biggest drop was felt by the small-cap Russell 2000, which suffered the largest weekly decline of the indexes listed here, and has lost most of its year-to-date gains. On the other hand, demand for 10-year Treasuries increased, sending yields to their lowest level since June.
