Johannesburg - Share prices on the JSE edged marginally higher for the third consecutive day on Wednesday morning, as investors wait for the US Federal Reserve's open market committee meeting to end later in the day.
Things can however change quickly if investors read too much in the Fed's statement after the meeting, particularly if they get the impression that the bank is more hawkish about the future movement of US interest rates.
Any promise of a strengthening in monetary policy in the US will not only boost the dollar further, but could lead to an outflow from emerging markets like South Africa as higher interest rates will attract investors back to their home market where the risks are perceived to be smaller.
