How is Financial Data extracted?

Here are some points that can satisfy your curiosity:

Building your scraper — If you are a learned developer, you can write and design the scraper in a particular programming language to automate the process of extracting data from the web.
It is crucial to remember not to disturb the website server by firing too many requests, as it can result in IP blockage, preventing you from extracting the data. However, this can make the process unscalable. But, this problem can be solved using a Google Finance API.

Google Finance APIGoogle Finance API is a perfect solution for businesses to increase the scalability and avoid blockage of any kind, as they are designed to handle or bypass the onsite protection by using proxy rotation and passing custom headers.

Sources of Finance Data

There are various sources of Finance Data available on the internet:

Stock Exchanges — Several stock exchanges like NSE, NASDAQ, and LSE provide complete financial data, including quarterly results, balance sheets, shareholding, etc., of the publicly traded companies.

Financial News Providers — Financial News providers like Bloomberg, Yahoo Finance, Google Finance, MorningStar, etc., are some of the best financial news providers in the market and are quality sources for scraping financial data.

Trading Platforms — The startup boom became evidence of the rise of many fintech companies and trading platforms. These platforms often provide a wealth of information, including real-time stock pricing, QoQ and YoY reports, historical performances, and much more.

Credit Rating Agencies — Credit Rating Companies like Moody’s, S&P, and Fitch Ratings provide in-depth research analysis on the creditworthiness of companies and governments. These ratings allow investors and financial institutions to calculate the risks associated with bonds, debt instruments, and financial stability.

Challenges in Extracting Financial Data

Extracting financial data at scale can present you with various challenges:

IP Blockage — If you are looking to scrape this data from trusted providers like Google, Bloomberg, or Yahoo then there is a high probability that your scraper might get blocked after a time by the anti-bot mechanism on these websites.

Legal Problems — Extracted data should only be used for legal purposes such as research and analysis. However, if any illegal activity is caught on notice, you must deal with the repercussions.

Scalability — The scraper might face scalability issues if it is not correctly optimized to extract huge amounts of data from the websites. This will cause a disturbance in the data pipeline and there would be no consistent flow of data.


A thorough financial information is always necessary when you are making an investment decision. Financial institutions always use web scraping to calculate the risk, investment returns, and probable losses associated with a specific entity. This data-driven approach of collecting data for in-depth research and analysis empowers investors to turn their fortunes toward success.
