Bulge bracket

Bulge bracket banks are the world's largest multi-national investment banks, serving mostly large corporations, institutional investors and governments. The term "Bulge Bracket" comes from the way investment banks are listed on the "tombstone", or public notification of a financial transaction;, where the largest advisors on investment banking operations (mergers, acquisitions, IPOs, or debt issuance) are listed first. The term is primarily related to the financial advisory side of the business, as opposed to sales and trading.
