Normal Market Size

The number of shares in a publicly-traded company that can be traded at a given price. The normal market size is a set number determined by the stock's market capitalization. Market makers must trade within the parameters of the normal market size. If a market maker wants to buy or sell more shares than the normal market size, he/she must negotiate a new price. The normal market size exists to keep particularly large orders from affecting the share price, thus reducing volatility.
