block (redirected from Conduction block)

Block

A large amount of the same security bought or sold by institutional or other large investors. There is no official size designation constituting a block of securities, but a commonly used threshold is more than10,000 equity shares or more than $200,000 of debt securities.

Notes:

Blocks of securities are traded in what are called "block trades" and serve to facilitate trades involving institutional investors or other large investors who require such bulk trades to meet their needs.
