SIA

Securities Industry Association (SIA) was established in 1972 through the merger of the Association of Stock Exchange Firms (1913) and the Investment Banker's Association (1912).
The Securities Industry Association brings together the shared interests of more than 740 securities firms to accomplish common goals. SIA member-firms (including investment banks, broker-dealers, and mutual fund companies) are active in all U.S. and foreign markets and in all phases of corporate and public finance.
The U.S. securities industry manages the accounts of more than 50-million investors directly and tens of millions of investors indirectly through corporate, thrift, and pension plans. The industry generates more than $300 billion of revenues yearly in the U.S. economy and employs approximately 700,000 individuals.
