What is Quantitative Finance? History and Definition.

Definition of Quantitative Finance

Quantitative finance is a subfield of investment management that makes use of mathematical and statistical techniques to conduct an analysis of investment possibilities across a variety of asset classes.

History of Quantitative Finance

Quantitative finance emerged in the middle to late 20th century as a result of the development of the financial markets leading to their expansion and increased complexity. Nevertheless, a few of the most important models and hypotheses were developed considerably earlier. Learn more about some of the most important quant finance practitioners and milestones by reading the following overview.

• The 1800s:-
• The early 1800s
• The movement of particles that were stuck within grains of pollen on a pool of water was discovered by Robert Brown, a Scottish botanist, in the year 1827. This observation is considered to be the foundation of one of the most important notions in the subject of quantitative finance. He took notice of the patterns that these particles traveled in, which seemed to be random. In addition to the concepts of drift and diffusion, this random movement came to be known as “Brownian motion,” which ultimately became an essential component of quantitative finance.

• The late 1800s:- In his book Calcul des Chances et Philosophie de la Bourse, which was published in the 1860s, Jules Augustin Frédéric Regnault used the idea of the “random walk” to investigate the contemporary notion of fluctuations in stock prices inside the stock market. Regnault, who worked as an assistant for a French stock broker, was one of the first authors to develop a “stock exchange science” that was founded on statistical and probabilistic research.

• The 1900s
• The early 1900s:-

A French mathematician named Louis Bachelier made a significant contribution to the field of derivatives in the year 1900 when he published his doctoral thesis titled “The Theory of Speculation.” In this thesis, Bachelier modeled the stochastic process that is now known as Brownian motion and used it to analyze stock options. This was a significant milestone for the realm of derivatives.

It is generally agreed that Bachelier was the first individual to do this, and his Bachelier model has been a pioneer in the creation of subsequent models that are commonly used, such as the Black-Scholes model.

Karl Pearson, an English mathematician and biostatistician, is credited with being the first person to use the phrase “random walk” in 1905. It is generally agreed that Pearson is substantially responsible for the establishment of the field of mathematical statistics.

The concepts that he presented in his book, “The Grammar of Science,” were subsequently incorporated into the ideas of Albert Einstein and other scientists.

With the work of Friedrich Hayek on efficient markets in the 1940s and the emergence of Modern Portfolio Theory following the publication of Harry Markowitz’s thesis “Portfolio Selection” in 1952, economists were laying the foundation for a more developed theory of financial markets by the middle of the 1900s. This was accomplished by laying the groundwork for future theories of financial markets.

Asset allocation, risk management, and attribution analysis are all areas in which institutional investors and financial advisers make extensive use of Modern Portfolio Theory. Markowitz was awarded the Nobel Prize in Economic Sciences in 1990 for his contributions to portfolio theory, which he had originally developed.

• The late 1900s

Eugene Fama, an American economist, expanded on this basis and advanced the discipline with his efficient market hypothesis (EMH) in the early 1970s. Fama’s work was a significant contribution to the field. Since Fama’s work laid a significant portion of the foundation for the field of financial economics as it exists today, he is sometimes referred to as the “Father of Finance.”

Since the work of Fama, the creation of a wide variety of quantitative models has been a logical evolution for individuals who are interested in analyzing stocks, determining the optimal risk-reward frontier, and engaging in portfolio optimization.

Edward Thorp, a mathematician who came to finance via his work on probability and statistics as they were used to the blackjack tables of Las Vegas, is another individual who played a significant role in the development of quantitative finance in the late 1900s. The blackjack game theory that Thorp developed was published in the book “Beat the Dealer” in 1966.

This book is widely regarded as the first guide to card counting when it was first released. In addition, Emanuel Derman, who was one of the first physicists to work on Wall Street, was a significant quant during this time period.

He was responsible for the development of a number of models that are still in use today, notably the Black-Derman-Toy model (BDT). Following the work that Fischer Black, Myron Scholes, and Robert Merton did in 1973 on the eponymous Black Scholes (Merton) equation, quant approaches and sophisticated computers became widespread in the derivatives market. This was due to the fact that option pricing and quant trading grew more prevalent in the 1970s and 1980s.
