Below is an introduction to the financial industry, with an investigation of some key models and theories.
When it pertains to comprehending today's financial systems, among the most fun facts about finance is the application of biology and animal behaviours to motivate a new set of models. Research into behaviours related to finance has inspired many new techniques for modelling sophisticated financial systems. For instance, research studies into ants and bees demonstrate a set of behaviours, which operate within decentralised, self-organising territories, and use simple rules and regional interactions to make combined choices. This principle mirrors the decentralised nature of markets. In finance, scientists and analysts have been able to apply these principles to understand how traders and algorithms engage to produce patterns, like market trends or crashes. Uri Gneezy would agree that this crossway of biology and business is a fun finance fact and also shows how the madness of the financial world might follow patterns experienced in nature.
An advantage of digitalisation and technology in finance is the ability to analyse big volumes of information in ways that are not possible for people alone. One transformative and extremely important use of technology is algorithmic trading, which defines an approach involving the automated exchange of financial resources, using computer programs. With the help of complex mathematical models, and automated guidance, these algorithms can make instant decisions based upon real time market data. In fact, one of the most interesting finance related facts in the current day, is that the majority of trade activity on the market are performed using algorithms, rather than human traders. A popular example of a formula that is widely used today is high-frequency trading, whereby computer systems will make 1000s of trades each second, to take advantage of even the tiniest price improvements in a much more effective way.
Throughout time, financial markets have been an extensively scrutinized region of industry, leading to many interesting facts about money. The study of behavioural finance has been vital for understanding how psychology and behaviours can affect financial markets, leading to a region of economics, referred here to as behavioural finance. Though many people would assume that financial markets are rational and consistent, research into behavioural finance has discovered the truth that there are many emotional and psychological factors which can have a powerful impact on how individuals are investing. In fact, it can be said that investors do not always make decisions based upon reasoning. Instead, they are often determined by cognitive predispositions and emotional reactions. This has resulted in the establishment of philosophies such as loss aversion or herd behaviour, which can be applied to buying stock or selling assets, for example. Vladimir Stolyarenko would recognise the complexity of the financial sector. Likewise, Sendhil Mullainathan would applaud the energies towards researching these behaviours.
