From: Webster's Revised Unabridged Dictionary (1913)

 Pyr·a·mid v. i. Speculation To enlarge one's holding or interest in a series of operations on a continued rise or decline by using the profits to buy or sell additional amounts on a margin, as where one buys on a 10% margin 100 shares of stock quoted at 100, holds it till it rises to 105, and then uses the paper profit to buy 50 shares more, etc. The series of operations constitutes a pyramid.  A similar process of reinvesting gains or winnings (as of a gamble), but not involving operation on margin, is called a parlay.
