The first detailed examination of the Amsterdam Stock Exchange emerged in 1688 with the publication of Confusión de Confusiones, a work that explored the complexities of financial speculation. Authored by a Sephardic merchant active in the diamond trade, this text analyzed behaviors and instruments that would later underpin the development of modern global market systems.
Early Life and Education
Born around 1650 to Isaac Penso Félix and Esther de la Vega, his early background was marked by the Sephardic diaspora. His father, a merchant who fled the Inquisition in Córdoba, established the family in Amsterdam. Joseph received an education from members of the Talmud Torah community, including Isaac Aboab da Fonseca and Moses Raphael de Aguilar, which cultivated his literary and intellectual pursuits.

He operated as a merchant in Amsterdam, with records indicating his professional activity included a bill protest on Portugal in 1679. Beyond his commercial interests, he was a prolific writer of poetry and moral philosophy. In 1673, he published a Hebrew drama titled Asire ha-Tiḳwah, which utilized allegory to examine the conflict between human will and passion. He also engaged with academic circles, serving as secretary for the Academy of the Flori in Amsterdam.
Analyzing the Amsterdam Exchange
His primary legacy, Confusión de Confusiones, remains an early study of market dynamics. Using a dialogue-based structure, he cataloged various speculative techniques such as options, futures, and margin buying. He identified patterns like herd behavior and overconfidence among investors, documenting the volatile reality of the Dutch East India Company and West India Company markets. His work serves as a record of early financial philosophy, though it was written primarily for the entertainment of his peers rather than as an instructional manual.
Final Years
His financial stability was challenged in August 1688 during the collapse of major Dutch trading companies, an event exacerbated by the financial crisis surrounding the invasion of William III. He maintained a massive correspondence, sending over 200 letters to various princes and statesmen during his career. He died in 1692 in Amsterdam and was interred at the Beth Haim cemetery in Ouderkerk aan de Amstel.
