Finance, as a field of study and an area of business, definitely has strong roots in related-scientific areas, such as statistics and mathematics. Furthermore, many modern financial theories resemble scientific or mathematical formulas.
However, there is no denying the fact that the financial industry also includes non-scientific elements that liken it to an art. For example, it has been discovered that human emotions (and decisions made because of them) play a large role in many aspects of the financial world.
Modern financial theories, such as the Black Scholes model, draw heavily on the laws of statistics and mathematics found in science; their very creation would have been impossible if science hadn’t laid the initial groundwork. Also, theoretical constructs, such as the capital asset pricing model (CAPM) and the efficient market hypothesis (EMH), attempt to logically explain the behavior of the stock market in an emotionless, completely rational manner, wholly ignoring elements such as market sentiment and investor sentiment.
