Johannesburg - The Johannesburg Stock Exchange said on
Friday it had identified and halted "incorrect" trades from one of
its member brokers, and would reverse the trades and lower the session's total
value after the close.
"Until end of day figures are adjusted after the close
of trade, the incorrect trades will distort today's trading value,"
exchange operator JSE Ltd [JSE:JSE] said in a statement.
"All incorrect trades will be reversed after the market
closes and today's trading value will be adjusted downwards."
The JSE's benchmark Top 40 - (Tradeable) [JSE:J200] index
was down 0.4% at 29,021.55 at 11:24 GMT.
The error was on the part of the broker and not the JSE,
said Michelle Joubert, head of investor relations at the bourse.
Both stock market and the broker were investigating the
incident, she said, it was unclear how many stocks were affected and how much
money was involved.
