Data Science Applications in Finance Industry

There are many data science applications in the field of finance. Let’s discuss these below.

1. Risk Analytics

Every company has some risk while doing business, and it has become essential to analyze the risk before taking any decision. Risk management is the method by which the risks involved while doing business can be identified, assessed, and measures must be taken to control the risk.

It is through proper risk management only that the profits of the business can be increased in the long term. Thus, it is very important to analyze the risks that a firm is facing properly. The use of Data Science Use Cases in Finance has made the method of risk management easier, particularly in financial markets. Analyzing the threat has become crucial for large companies for their strategic decision making and is called Risk Analytics. For Business intelligence and Data Science Use Cases in Finance, Risk Analytics has become vital areas.

A company can increase the security and trustworthiness of the company using risk analytics of data science. Data is the core of Risk Management and Risk Analysis because it measures the gravity of the damage and multiplies it with the frequency of loss. The knowledge of problem-solving, statistics and maths is essential in the field of Risk Management for any professional.

Raw Data majorly consists of unstructured data which cannot be inserted into a standard excel spreadsheet or a database. Data science plays a significant role in this using their frameworks to analyze the data.

A company faces various kinds of risk which can originate from the market, credits, competitors, etc. The first step in managing the risk is identifying the threat. After that, monitoring and prioritizing the risk is essential.

A risk analyst has first to analyze the loss and the pattern of the loss. It also has to identify the source of loss. Financial data science helps to create models that help in analyzing areas.

A company can use massively available data like financial transactions and customer information using which they can create a scoring model and optimize the cost. This is an essential aspect of risk analysis and management which is used to verify the creditworthiness of a customer.

The past payment records of a customer must be studied, and then it must be decided whether the loan is to be paid to the customer or not.  Many companies now employ data scientists to analyze the creditworthiness of customers using machine learning algorithms to analyze the transactions made by customers.

2. Real-Time Analytics

In the earlier period, data were processed and analyzed in batches which means one by one and not real-time. It had a huge disadvantage of data being old by the time it was processed and analyzed. The decisions taken on historical data will not be very helpful or accurate.

Real-time analytics means a huge amount of data is being generated and analyzed continuously. It is a continuous process. The use of data science in finance makes the process much easier. Machine learning algorithms perform real-time analytics of data. Real-time analytics is very important because old data is of no use to the firm. It is a setback for the firm. Firms need to analyze the constant changes to be at par with the market and preferences of the customers.  

Many various industries started having a problem because they require real-time data to gain insights about present circumstances. However, now it is possible to access the data with minimum delay due to the development of dynamic data pipelines and advancements in technology.

Data Science has now become a very crucial part of Finance and Financial Institutions to keep track of all financial attributes, credit scores and transactions without any issue of latency. Read about the contribution of Data Science to the banking industry.

3. Consumer Analytics

Many financial institutions have consumer personalization as their major operation. With the help of data scientists, companies can gain insight into the behaviour of consumers in real-time with the help of real-time analytics to make better strategic business decisions. Data Science is being used in many financial institutions such as insurance companies to understand the consumer to reduce losses by eliminating below zero customers, to increase cross-sale and to measure the lifetime value of a customer.

By observing the behavior of different customers by means of financial data science, a data scientist can make the best use to increase the purchasing habits and frequencies of potential customers by following the below-mentioned techniques –   

Bifurcation of customers as per their habits – Customers can be bucketed into different segments, for example, a tech-savvy customer from an online platform is expected to buy latest products more frequently than the ones who purchase only based on the requirement. There are other segments of customers who generally wait for special sales offers. 

Offer to enhance customer purchase capacity – With this tool, a business house lures a periodic customer to purchase 25 to 30% more of its periodic purchase value by offering him attractive schemes. 

Prevention of attrition – Sometimes, customers tend to switch over service providers or brands in view to get more value for their money. Switching between different brands of cell phones or cellular data service provider is the most common example of attrition cells. Business houses try to capture the customer grievances and address them with value-added offers thereby preventing attrition.

4. Customer Data Management

Firms record the purchases and buying habits of the customers. Their choice and preferences are taken into account. Data science in finance helps in analyzing the purchasing trends of the customer and serving the customers according to their choices. 

Data is everything, and the financial institution needs customer data for processing and analyzing the information. The functioning of financial institutions has completely revolutionized after the introduction of big data in the world of data science. Large numbers of transactions and social media have contributed a lot to the variety and volume of data.

There are mainly two types of data available, which are Structured Data and Unstructured Data. It is effortless to handle, process and analyze the structured data as it is already in a specific format. But in the case of Unstructured Data, It is not as smooth as structured data to process and analyze it. Various top data science tools are used to process and handle unstructured data. 

One of the most important aspects of Big Data is Business Intelligence which is extracted by using machine learning to gain insight about the customers and their behaviour. Meaningful insights from data can be generated using various tools such as text analytics, data mining, Natural Language Processing (NLP) and many more. A thorough analysis is conducted on the data of customers using machine learning algorithms to analyze the changes and trends in the financial market and values.
