Johannesburg - Shares of Old Mutual jump more than 3 percent to lead Johannesburg's Top-40 index after robust sales by the Anglo-South African financial group boosted full-year profit.

However, volatile currencies in South Africa and other emerging markets kept profits flat.

Adjusted operating profit of 1.6 billion pounds was unchanged from a year earlier but represents 15 percent growth on a constant currency basis.

The company that is also listed in London says it will pay a 6 pence final dividend, bringing the total for the year to 8.1 pence per share. - Reuters
