LONDON/NEW YORK, (Thomson Reuters Accelus) – A decision by the UK Financial Services Authority (FSA) to¬†fine hedge fund manager David Einhorn and his Greenlight Capital fund 7.3 million pounds ($11.5 million) has highlighted the need for professional investors to ascertain clearly what constitutes inside information, securities lawyers said. The FSA said that it fined Einhorn 3.64 million pounds and Greenlight Capital 3.65 million pounds for using inside information that he obtained from a broker before selling shares in a UK public company in 2009. Einhorn’s is the biggest scalp by far of the FSA’s renewed determination to punish market manipulation as part of its “credible deterrence” policy.
