Between January and June 2015, Finanssivalvonta, the Finnish financial and insurance regulator, investigated 102 cases of suspected securities market abuse, as opposed to 86 in the previous 12 months.

Of these cases, 41 (26) are related to the abuse of insider information, 27 (18) to market manipulation, 30 (34) to the disclosure obligation under the Securities Markets Act, and 4 (8) to other types of abuse.

FIN-FSA, as it abbreviates itself, acts on its own suspicions about market abuse, but it also receives information about suspicious cases through notifications and tips from high-net-worth investors, the stock exchange, market participants, the media and foreign supervisory authorities. From domestic and foreign investment service providers between January and June it received a total of 37 notifications, as opposed to 30 in the first half of 2014). A major proportion of these came from domestic service providers. The stock exchange sent it 15 notifications (13 in the first half of 2014).

The number of notifications has been increasing, partly due to improvements in investment service providers’ own control systems and partly due to a lower notification threshold for some market participants. A notification related to market abuse is not in itself a request for an investigation but refers instead to an exceptional transaction or something triggered off by a firm's obligation to notify, perhaps involving the background to a transaction. Also imporant are the obligation to disclose major shareholdings and the offering of securities.
