Tech-heavy Nasdaq reached 6000 for the first time in its history last Tuesday. The small-cap Russell 2000, which surged for much of 2016 but fell back earlier this year, rebounded over the past few weeks, attaining a record high of 1419.43 by midweek. Better-than-expected quarterly corporate earnings reports, a sign of sustained strength for many large companies, have pushed stocks higher. Each of the benchmark indexes listed here posted notable gains last week, led by the Global Dow, which rose over 2.50%, followed by Nasdaq’s 2.32% climb. Long-term bond yields increased on news of proposed tax cuts.
