South African regulator reviewing volatile share trading

A South African market regulator said on Friday it was reviewing volatile share trading sparked by market speculation that a research group would release a negative report on a listed firm.

The regulator confirmed in an emailed response to questions it was reviewing unusual activity in shares of Aspen Pharmacare, which plunged 10 percent on Tuesday, prompting the company to say there was speculation that New York-based Viceroy Research would release damaging information about the company.

Aspen, whose shares have since recovered, said it had never been contacted by Viceroy.

The Financial Services Board (FSB) was working with the Johannesburg Stock Exchange to determine whether to open a formal investigation, FSB spokeswoman Tembisa Marele said.

“The specific mandate of the FSB in this area, according to the Financial Markets Act is to investigate cases of insider trading; price manipulation; and false reporting,” Marele said.
