A Little More on What is a Blockage Discount

When traded securities have a value of over $200,000, this can be called a block trade. A block trade often involve the trade of more than 10,000 shares in the bond market. Block trades refer to exchange of large number or amount of securities. In a block trade, it is possible for depression in price to occur, often times, this is as a result of low market volume.

To avoid depress in price, traders can give away their large securities in bits over a period of time.
