With keen insight and an unexpected good humor, this 1922 volume on the vagaries of the stock market and the psychology of those who play it is still required reading for investors today. From harnessing Hoyne's "speculative force"'-the tendency to transform into advantageous action the result of using one's brain-to overcoming greed and fear, taking advantage of news and gossip, and making the rules and principles work for you, contemporary speculators will find much to enjoy and learn here.American author THOMAS TEMPLE HOYNE (1875-1946) also wrote Intrigue on the Upper Level: A Story of Crime, Love, Adventure and Revolt in 2050 A.D. (1934), the humorous On Pilgrimage (1938) and other books.
