South African equities scaled multiple lifetime records for much of 2013 as the U.S. Federal Reserve bond-buying policy encouraged investors to seek risky assets in less-developed markets.
But the Fed is reducing that stimulus package and upbeat jobs data earlier this week has increased expectations the scaling back might be more aggressive than anticipated.
European stocks extended a rally into a third day on Thursday, betting on further economic improvements in the bloc, while U.S. shares rose at the open on upbeat labour market data.
Johannesburg's market volume is remains low with some traders and investors still away. Some 148 million shares were traded, according to preliminary bourse data, with decliners outpacing advancers 171 to 150.
