(23)Articles 142 and 143 of the FMIA prohibit insider trading and market manipulation by any person. In addition, under the conditions of Articles 154 and 155 of the FMIA, the exploitation or the attempted exploitation of insider information and price manipulation constitute criminal offences. The stock exchange must issue regulations regarding the disclosure of inside information by issuers. Under the Listing Rules of a stock exchange, the issuer must inform the market of any price-sensitive facts which have arisen, or are about to arise, in its sphere of activity, as soon as it becomes aware of such information. Price-sensitive facts are facts which are capable of triggering a significant change in market prices. Disclosure must be made so as to ensure the equal treatment of all market participants. Further, under Article 31(1) of the FMIA, Swiss stock exchanges are required to monitor price formation and the transactions executed on the stock exchange with a view to detecting insider trading, price and market manipulation and other breaches of statutory and regulatory provisions. To this end, a stock exchange must also review transactions which are conducted outside of the trading venue and which are reported to it or brought to its attention in some other way (Article 31(1) of the FMIA). This supervisory task must be carried out by an independent body of the stock exchange. Issuers must be able to provide FINMA upon request with an insider list based on their duty to provide information, including all additional information and documents that FINMA requires to carry out its tasks (Article 29(1) of the FINMASA in conjunction with Article 145 of the FMIA). A stock exchange must notify FINMA of any suspected breaches of the law or other irregularities. If the breaches in question involve criminal offences, it must also inform the competent prosecuting authority without delay (Article 31(2) of the FMIA). FINMA investigates on information about violations of the law received from stock exchanges, as well as based on its own market monitoring with the aim of enforcing the provisions of supervisory law that prohibit market abuse.
