The Sensex Index on India’s Bombay Stock Exchange traded on Thursday up 4.9% since Dec. 31. The index slumped 4.2% during the same period last year, hitting its low on Feb. 5, then turning to rally nearly 30% for the year. That rally began as polls showed centrist candidates in favor ahead of the pending election. When the votes were all tallied in mid-May, the right-wing Bharatiya Janata Party held an outright majority.
