With today’s gains, major indices have closed higher in eight out of the past 11 trading sessions, but volumes have been light, suggesting some investors are remaining on the sidelines as geopolitical tensions simmer. The Dow Jones Industrial Average climbed 214 points, or 0.9%, to 24787, its highest close since March 16. The S&P 500 added 1.1%, as 10 of the index’s 11 sectors traded higher, while the tech-heavy Nasdaq Composite rose 1.7%. Those indices ended at their highest levels since March 21. Tuesday’s rally helped propel the Dow industrials back into the black for the year. The blue-chip index is up 0.3%, while the S&P 500 has gained 1.2% and the Nasdaq Composite has risen 5.5%.
