Australian National University academic Dr Dean Katselas has studied the trading of shares by directors following the release of listed companies’ earnings announcements. He says directors typically sell shares when positive information about their company is released and spark a jump in its share price, while they buy shares after the release of negative information that sees the share price depressed. Katselas says ‘contrary’ share trades are being made on the basis of non-public information about a company’s future performance, which he says essentially amounts to insider trading.
