When Stock Market Theory and Practice was written, there seemed the definite need for a comprehensive volume which should tell the reader “all you ought to know” about the stock market – its theory, its principles, its successful trading practices. Stock Market Theory and Practice was designed to give the individual a full and complete background of basic knowledge with which to pursue his general market activities. Schabacker has designed the present volume with an eye to getting the most in profit out of average market operation with the minimum of personal research, statistical background, and necessary attention. No attempt has been made to cover the entire field of market technique, particularly the more specialized and scientific fields. His attempt has been to present a purely simple rationalization of the entire scheme of market action and market activity, to boil the whole thing down to a common-sense and logical approach which even the inexpert and far-from-professional layman can easily understand and profitably apply.
