One of the more interesting aspects of the Mosman Oil & Gas (MSMN) story involves the nature of price sensitive information. When Mosman announced its first oil “discovery”, at 11:42am on June 13th, the share price went ballistic. Having opened at 11.85p, Mosman’s stock had just hit an intraday low of 10.5p before the company delivered its joyous news. By the end of the next trading day, Mosman’s share price had peaked at 56p, giving the company a market cap of £36.3million. Four days later and Mosman placed at 23p to raise £3million. There is no doubt that Mosman’s news release was a price sensitive event, but is it time to revisit the definition of what constitutes price sensitive information?
