The subject stocks usually have little or no liquidity prior to the block purchase. After the block is purchased, the firm's participating brokers will sell the stock to their brokerage customers at the then-current quoted offer/ask price, to the often victimized investors who are generally unaware of this practice. This large difference, or "spread" between the then-current quoted offer/ask price and the deeply discounted price the block of stock was purchased is almost always shared with the stockbroker at the firm who solicited the trade. For this reason, there is a large benefit and an inherent conflict of interest for the firm and the broker to sell these "proprietary products".
