Introduction
Determining investment decisions in the stocks of a company, as well as analyzing cash flow statements, are the concepts of using technology, programs with complex algorithms, and mathematical calculations to collect, process, and analyze data. Because of the collected data, it is possible to predict future trends, make decisions and learn useful details. Such forecasts are important when creating risk management systems or determining the potential movement of the financial market. There are many options for using data with the help of R and Python, and with the proper configuration of the commands of these programming languages, it is possible to conduct financial analytics.
Python for Financial Data Analysis
Programmers created Python as a general-purpose language, and later it adapted to the specific tasks of data analysis. This is where the main advantages of this language follow. When analyzing data, its use is optimal for web scraping and crawling (beautifulsoup, Scrapy, etc.), effective work with databases and applications (sqlachemy, etc.), implementations of classic ML algorithms (scikit-learn, pandas, NumPy, scipy, etc.), and tasks Computer Vision. There are many reasons to use Python, but “the main reason for using Python is that it is growing faster than predicted in the finance sector, giving way to a faster and better analysis of the stock market” (Garita 4). Based on this, it can be argued that Python can help to make informed and less risky decisions when it comes to investing in the stock market. In order to conduct such an analysis, it needs to download financial data for certain time periods. For using this, it is better to exercise the Pandas extension to link to financial data from Google Finance, Quandl, Enigma, and other databases.
Python is a good choice for doing the quantitative analysis of a company’s cash flow, which is related to the study of big financial data. With libraries such as Pandas, Scikit-learn, PyBrain, or other similar modules, it is possible to manage enormous databases and visualize the results. In this way, it is practicable to easily generate price charts and other trends in the financial world. Python for finance analytics can teach machine learning systems to collect information about company statistics, news reports, earnings results, and other useful information. Any of these aspects can be directly related to the future of the company. However, all stock investments are risky, and even experienced financial data analysts or machine learning can be wrong.
Python for finance analytics has many advantages and a competitive edge to lead the financial industry to success. One of the reasons is a strong ecosystem of millions of users, frameworks, and lessons. The financial sector is approaching a new era because of Python and its libraries. Due to the increasing amount of financial data, people are no longer able to professionally analyze and evaluate them. Therefore, machines have come to replace people in this sector and, at incredibly low cost and at high speed, perform financial data analysis. There is a close relationship between artificial intelligence (AI) and finance. Consequently, it is not at all surprising that Python has become the main language for AI-based data analysis.
Python, in the financial industry, is the leading programming language for performing quantitative and qualitative analysis. This language is involved in the development of payment and online banking solutions, the analysis of the current situation in the stock market, reducing financial risks, determining the rate of return of stocks, and much more.
In addition to this, Python for finance is a popular choice due to its powerful framework for building neural networks and artificial intelligence. Such machine learning models can make predictions on the collected data. This fact and the ease of use of Python make it ideal for use in financial sector information analytics.
R for Financial Data Analysis
Among the advantages of R, it can be noted that many researchers have developed excellent packages for financial data analytics. In addition, the capabilities of R packages are improving quickly, and this trend will continue in the future, which means new opportunities for financial data analytics. In addition, R is an open source, so many new packages are regularly developed for it for different use cases and unlike analytical tasks. R also has a many variabilities when it comes to the information displayed. With the right set of commands, R can show functional information, “in finance and economics, this can be the current price of a stock, the value of an economic index such as inflation, the result of academic research, among many other possibilities” (Perlin 32). Using R is convenient for loading financial data, for example, from resources such as Google Finance and Yahoo Finance. The undoubted advantage of R is the possibility of advanced statistical analysis for a number of specific areas of science and practice (econometrics, bioinformatics, etc.). In R, time series analysis is still much more developed at the moment. Another key and, so far, undeniable advantage of R over Python is interactive graphics. The possibilities for creating and customizing dashboards and simple applications for people without JS knowledge are truly enormous. R is also compatible with other programming languages such as Python or C++. Therefore, another of its advantages can be called the fact that it is easy to integrate code from other programming languages into R. This means that the user is not limited to only one programming language, choosing R as the main one.
R has the following advantages: many packages have been written for this program to solve a wide range of problems. The program is flexible: the sizes of any vectors and matrices can be changed at the request of the user, and the data does not have a rigid structure. This property is extremely useful in the case of forecasting when the researcher needs to make a forecast for an arbitrary period. There are many considerable solutions for comparability of system versions and packages, helping to apply the principles of literate programming.
Conclusion
Taking into account all the information studied, we can conclude that Python is the best choice for financial data analytics. Python can be called the leading language in various financial sectors, including banking, insurance, management and investment, and so on. Python helps generate tools used for market analysis, financial model design, and risk mitigation. According to Garita, “…Python is easy to use, and with the use of Jupyter Notebooks, it has become extremely helpful considering data analysis” (2). By using Python, companies reduce costs by not spending so many resources on data analysis. In addition, the workflow is so efficient that a two-month analysis can be completed in a day.
Nonetheless, R, together with a strong ecosystem, is also a good choice under purposes in data analysts and especially organizations. Knowledge of R is also one of the advantages that will help to analyze large amounts of data in the financial sector. Therefore, given the mutual compatibility of the programming languages under consideration, it is possible to use them in symbiosis for more productive analytics.
