DEFINITION of 'Blue Sheets'
Requests for information sent out by the Securities and Exchange Commission to market makers, brokers and/or clearinghouses. Blue sheets ask for information related to specific securities or transactions and are often requested in order to determine if there has been any illegal activity or to determine why, for example, a certain security experienced a large level of volatility.
BREAKING DOWN 'Blue Sheets'
Blue sheets provide the SEC with detailed information about trades performed by a firm and its clients. The information includes the security's name, the date traded, price, transaction size and a list of the parties involved.
The questionnaires came to be known as blue sheets because they were printed on blue paper. Today, due to the high volumes of trades, this information is provided electronically though electronic blue sheet systems or EBS.
