To successfully invest in the market, you need to simultaneously solve many problems: choose the right stock, find the right time for purchases and sales, limit losses in time and fix profits. Failure to properly solve these problems has led many investors to ruin during the period of the fall of the stock market. William O'Neil, author of the best-selling book "How to Make Money in the Stock Market", in his new book tells readers how to avoid fatal mistakes and increase their capital. All the provisions of O'Neill's investment methodology are illustrated on a variety of charts of prices for American stocks. Despite the simplicity of the presentation, the book details the methods of comprehensive market analysis that will be of interest to both private investors and speculators, as well as employees of investment companies, banks, as well as students of economic specialties.
