Financial engineering is not a traditional branch of engineering. It is rather a methodological approach to incorporate theories and principles of mathematics while solving financial problems. This technique has various benefits mainly because it involves limited to no risks.

Moreover, it helps integrate information from fields like economics, computer science, mathematics, and financial theory. This technique can also convert financial theories into practical applications.

Financial Engineering is the application of engineering techniques or mathematical calculations to solve financial problems. It uses data and facts from subjects like statistics, economics, mathematics, computer science, etc., to address current financial situations. This technique's main objective is converting financial theories into practical applications.

Financial institutions like commercial banks and insurance agencies usually use this technology. Moreover, it is commonly known as quantitative analysis as it works as a measurement metre.

This engineering technique uses investment analysis, the latest financial models, trading methods, and many more to work effectively. With the help of mathematical modelling and computer science, it can issue new tools for solving the required financial problem. Professional financial engineers handle all these tasks in their various working fields.

These financial engineers can predict investment tools' performance, applicability, and profitability by managing quantitative risk models. Moreover, they can understand and handle the unpredictable market and provide knowledge on various product offerings' risks. Other than this, the engineers here use options trading as an effective and proven model for this technique.

Therefore, you can collectively say that financial engineering is used for various purposes, which are as follows:

• Security analysis
• Portfolio management
• Trading and arbitrage, as well as algorithmic trading
• Setting a price for derivatives and options
• Risk management which includes managing credit risk
• Analysing behavioural finance
• Machine Learning for investment strategies

The different types of this engineering techniques are as follows:

• Derivatives Trading: Derivatives trading is where the value of derivatives depends upon the performance of their underlying assets or securities. Similarly, the process of this technique to solve financial problems by estimating the value of its underlying assets is identified as derivative trading.
• Foreign Exchange Market Trading: In foreign exchange market trading, currency exchange rates play an important role. Based on changes in these rates, firms sustain funds by holding different currency values from various countries. Similarly, by this engineering technique, engineers can predict the rise or fall in currency value by estimating changes in exchange rates.

The main advantages or benefits of using this engineering method are as follows:

• Less Risk: While operating in a company whose business is in another country, it can be subject to significant currency or price fluctuations. This engineering method helps reduce such risks by providing products that stabilise your business against future volatility.
• Offers Compensation: As a business owner, you will be looking for ways to retain key employees and engage high-performing management to provide stock in the business. This strategy can be very useful for the business, especially during its growth phase, as it can improve the performance of higher-priced stocks. This engineering technique helps understand the consequences of entering stocks over cash in the company’s balance sheet and income statements.
• Contingent Payments: Your business can use financial engineering strategies and products for providing contingent payments to contractual provisions. This is also possible in the case of a convertible loan or other business agreements, as well as to control risky business ventures or opportunities. Therefore, by creating a solution providing minimum loss for your business, you can participate in the profit and limit your company's losses.

The disadvantages or limitations that you may come across here are as follows:

• Increased Complexity: Although this engineering method has many benefits, its main disadvantage is its complex process. This technique uses various complex mathematical formulas and equations to solve various problems. Now, if engineers make a slight mistake while solving them, it can create huge complexities resulting in starting the entire procedure from the beginning.
• Difficult for Investors: Though this technique helps in solving the financial problem of investors or business owners, they cannot use it themselves. An engineer needs to handle this problem by themselves to ensure the entire financial or quantitative engineering process is not of much use. Moreover, as already discussed, due to the complexity of this technique, everyone will not be able to understand it and apply it effectively.

Therefore, financial engineering uses a quantitative risk model to forecast the performance of an investment tool. It also helps predict whether a new security in the financial world would be profitable in the long run. Moreover, you can get a brief idea about the risks of these new securities before investing in them. As an investor, you can know all the challenges associated with these securities.
