Johannesburg - South African shares sink to a one-month low as investors globally dump risky assets such as emerging market stocks.

Overnight market talk of a hedge fund liquidating big positions in commodities, as well as worries the US Federal Reserve could prematurely wind down its bond buying programme, has rattled investor sentiment around the world.

Johannesburg's Top-40 index is down nearly 1 percent at 35,671.43 and the wider All-Share index is 0.9 percent weaker at 40,081.02. - Reuters
