When an earlier version of this book was published twelve years ago, many of the technical timing tools that were explained were used mainly in the futures markets. Over the past decade, however, these tools have been widely employed in analyzing stock market trends. The technical principles that are discussed in this book can be applied universally to all markets—even mutual funds. One additional feature of stock market trading that has gained wide popularity in the past decade has been sector investing, primarily through index options and mutual funds. Later in the book we'll show how to determine which sectors are hot and which are not by applying technical timing tools.
