Top 6 Quotes & Sayings by Joseph Granville

Joseph Ensign Granville, often called Joe Granville, was a financial writer and investment seminar speaker. He is most famous for inventing and developing the concept of "On-balance volume (OBV)". Granville argued that when volume increases sharply without a significant change in a stock's price, the price will eventually increase rapidly, and vice versa. On balance volume is thus one tool of technical analysis that attempts to predict future prices of stocks, commodities, and other financial assets traded on financial markets for which historical price and volume information is available.
