This book is the first that describes the practices of any stock exchange; it makes evident a high development of practices, with puts, calls, pools, and manipulations; and it appeared as early as the seventeenth century. Not inappropriately the stock exchange described is that of Amsterdam, a city which at the date of the volume’s publication —1688 — was still the leading financial center of the world. The book, to be sure, is hardly a systematic account of the institution; the author pursued moral, philosophical, and rhetorical objectives, and, while saying a lot that seems now to be of little value, manages somehow to leave unsaid a great deal that would be of interest for us. Nevertheless, it represents, even in its peculiar form, a really important source of information about the stock exchange, and indeed about the Dutch business world of that period.

2013 Reprint of 1957 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition Software. Joseph Penso de la Vega, best known as Joseph de la Vega (ca.1650-1692), was a successful Jewish merchant, poet, and philanthropist residing in 17th century Amsterdam. He became famous for his masterpiece "Confusion of Confusions" the oldest book ever written on the stock exchange business. Although not a descriptive account of the process of stock trading, Penso presented the history of speculation in stocks and acquainted the reader with the sophisticated financial instruments used. The dialogue format allowed the reader to understand the respective perspectives of the various market participants and the intricacies of speculation and trading. Penso also came up with four basic rules of the share market that are still of the greatest relevance today: The first rule in speculation is: Never advise anyone to buy or sell shares. Where guessing correctly is a form of witchcraft, counsel cannot be put on airs. The second rule: Accept both your profits and regrets. It is best to seize what comes to hand when it comes, and not expect that your good fortune and the favorable circumstances will last. The third rule: Profit in the share market is goblin treasure: at one moment, it is carbuncles, the next it is coal; one moment diamonds, and the next pebbles. Sometimes, they are the tears that Aurora leaves on the sweet morning's grass, at other times, they are just tears. The fourth rule: He who wishes to become rich from this game must have both money and patience. Includes Foreword by Hermann Kellenbenz.

A few words will suffice to justify the preparation of an introduction to English readers of Joseph de la Vega and 's Confusion de Confusiones. His book is the first that describes the practices of any stock exchange; it makes evident a high development of practices, with puts, calls, pools, and manipulations; and it appeared as early as the seventeenth century. Not inappropriately the stock exchange described is that of Amsterdam, a city which at the date of the volume and 's publication — 1688 — was still the leading financial center of the world. The book, to be sure, is hardly a systematic account of the institution; the author pursued moral, philosophical, and rhetorical objectives, and, while saying a lot that seems now to be of little value, manages somehow to leave unsaid a great deal that would be of interest for us.

This account of the sophisticated financial hub that was 17th-century Amsterdam “does a fine job of bringing history to life” (Library Journal). The launch of the Dutch East India Company in 1602 initiated Amsterdam’s transformation from a regional market town into a dominant financial center. The Company introduced easily transferable shares, and within days buyers had begun to trade them. Soon the public was engaging in a variety of complex transactions, including forwards, futures, options, and bear raids, and by 1680 the techniques deployed in the Amsterdam market were as sophisticated as any we practice today. Lodewijk Petram’s award-winning history demystifies financial instruments by linking today’s products to yesterday’s innovations, tying the market’s operation to the behavior of individuals and the workings of the world around them. Traveling back in time, Petram visits the harbor and other places where merchants met to strike deals. He bears witness to the goings-on at a notary’s office and sits in on the consequential proceedings of a courtroom. He describes in detail the main players, investors, shady characters, speculators, and domestic servants and other ordinary folk, who all played a role in the development of the market and its crises. His history clarifies concerns that investors still struggle with today—such as fraud, the value of information, trust and the place of honor, managing diverging expectations, and balancing risk—and does so in a way that is vivid, relatable, and critical to understanding our contemporary world.
