pyramiding

pyramiding - Investment & Finance Definition

Using paper profits from one investment as collateral to buy further positions while using a margin loan from a broker. This is a risky strategy because of the potential for prices to fall. Pyramiding also may occur if unrealized profits on existing futures positions are used as a margin to increase the size of the positions in successively larger increments.
