Python For Finance

Financial institutions are increasingly evolving technologically. Technology and innovation bring speed to operations that can make a big difference in an organization’s competitiveness, even more so with so much information. As a result, many companies have used Python for finance.

Python is among the three most popular programming languages for applications in financial services. For this reason, Python is among the most sought-after languages ​​by banks.

Because of all this importance, in this article, we will show you why institutions use Python for finance in their tasks, through the following content:

How to use Python in the world of finance?

Python is a versatile programming language that has become very popular in data science and for data analysis. Companies around the world are using Python to gather and process the information they need.

It is an easy language to program and implements, making it perfect for use in financial services applications, which are almost always quite complex.

For this reason, the  Python domain for finance has become one of the most sought-after skills. Large institutions in this field, such as banks and insurance companies, are looking for programmers with expertise in this language.

Compared to other languages ​​used by financial analysts, such as VBA in Excel, Python is much simpler to learn. In addition, it also has several frameworks and libraries that assist in programming.

It is clear that for very complex tasks, it is necessary to use more advanced languages ​​and technologies. However, Python is quite powerful and can handle day-to-day tasks with ease.

Because it has a  simple and easy-to-understand syntax, application development is very fast. So it is ideal for solving the tasks and demands that arise, quickly solving problems, and building the necessary software.

At the same time, it reduces the number of errors in the code, which is very important when developing products for an industry as serious as the financial market.

All of these features make Python ideal for finance. It solves complex problems easily,  effectively, and quickly. This speed and assertiveness are very important in a market like the stock market, where there are changes all the time.

For this reason, it is also used to create stock buying and selling strategies automatically, using data analysis and with the help of frameworks such as Flask and Django.

Now, let’s look at some practical Python applications for finance:

1. Download stock quotes from the Stock Exchange

We can use language to automate the stock analysis process. A relatively simple task is to download stock quotes in a specific period: the day, the month or even the period of months and years.

It may seem rudimentary, but this is the basis for carrying out more complex tasks , such as creating artificial intelligence algorithms to automatically analyze this collected information.

2. Analysis of the main stock indicators

Python is widely used for financial mathematics, that is, solutions that process and analyze large amounts of financial data. Some libraries simplify the information visualization process and allow sophisticated statistical calculations.

3. Creating graphics

The value of a stock varies over time, depending on whether it values ​​it or not. This appreciation depends on many other market factors and the company itself.

Trends, profit and loss, debts, and scandals: are all variables that can bring down or increase the price of a share.

This behavior of an action over time can be valuable information for predictive analysis of the value of a company in the future.

This is done through a trend check, which reflects on the asset’s value, and the identification of resistances (limit values) and supports (minimum values).

4. Calculation of risk and return on individual shares

The stock market generates several types of information that require analysis. That’s exactly why Python for finance is so good: we can use it to create programs that identify the best trading and stock offering strategies.

Algorithms can perform predictive analysis on market conditions. We can create sophisticated programs, which incorporate several indicators on a specific stock in the code, calculating the purchase risk and the possibility of the return of each stock.

The indicators are already calculated by financial institutions, and we can use them as variables within the algorithm, or we can create codes to calculate these same indicators.

5. Building an optimized stock portfolio

From all the other applications we have mentioned, you can create your optimized stock portfolio. The use of Python for finance makes it possible to choose assets that will bring higher returns, and assist in the decision to buy, or not to invest in a stock.

As this market is very volatile and varies quickly, the use of this language helps a lot in the formation of the personalized stock portfolio, gathering the data, and bringing greater reliability to the choices, through well-founded analyzes.
