Zimbabwe’s stock index rose for a 16th day, its longest winning streak in a year, as investors speculated President Robert Mugabe’s government will put in place policies supportive of economic growth. The gauge slumped to an eight-month low on 5 September, falling 24 percent after reaching its highest level in more than four years on 1 August. “The signs have been reasonably positive. The government has put measures in place that would take the country forward. It also said it will keep on engaging with industry on harmonizing of the indigenization program for what is best to industry,” a market analyst said.
