Definition,block shares, A large number of company shares, usually 10,000 or more sold in bulk in a single trade. Block trading is a useful measure for analysts in order to assess where institutional investors are pricing a stock. Because in a merger or acquisition, a bid needs to "clear the market" (i.e. enough shareholders need to tender), it is most useful to see at what prices large blocks of stock are trading. These prices imply what the largest shareholders are willing to sell their shares for; therefore, in block trading analysis, small trades are ignored to avoid skewing the data.
A block trade, also known as a block order, is an order or trade submitted for the sale or purchase of a large quantity of securities. It involves a significantly large number of equities or bonds being traded at an arranged price between two parties, sometimes outside of the open markets, to lessen the impact on the security price. In all, 10,000 shares of stock, not including penny stocks, or $200,000 worth of bonds are considered a block trade.
