You suspect an irregular trade on the stock exchange

SFMA analyses unusual securities trading as part of market supervision, including sharp price movements, high volatility and unusual trading volumes.

How suspicious trading is assessed

After initial checks, SFMA decides whether more detailed supervisory investigations or formal proceedings are required. If criminal conduct may be involved, the matter can also be referred to the competent criminal authorities.

Stock exchange surveillance

SFMA works with the trading surveillance units of the stock exchanges. Within self-regulation, those units monitor price formation, examine irregularities and inform SFMA where a case may be relevant under supervisory law.

Limits for individual losses

A report about suspicious trading can support market supervision, but SFMA cannot compensate individual losses or provide case-by-case investment assessments. Financial-loss claims must be pursued through the appropriate legal channels.
