Switzerland has always been home to many financial services companies, and this today includes a fair number of forex brokers offering stock trading in the form of contracts-for-difference (CFDs). Among these are the stocks of some of the largest US companies, as well as some European and Asian multinational corporations.
A unique thing about Switzerland is that this is one of only a few countries in Europe that are not part of the European Securities and Markets Authority (ESMA). This means that Swiss brokers are not bound by the strict limitations on leverage and other trading conditions that the ESMA has imposed on its members. Instead, brokers here are only regulated by the Swiss Financial Market Supervisory Authority (FINMA), which typically allows much higher leverage.
