BREAKING DOWN 'Blockage Discount'

A block of securities will typically consist of 10,000 shares or debt securities valued over $200,000. Traders want to unload all of the securities quickly, but are often limited by market volume. To facilitate a fast exchange, a trader will sell the assets at a discount to another institutional investor.
