Get current stock price in Python
In this article, we have covered how to get the current stock price in Python from Yahoo Finance using two Python libraries, Beautiful Soup, and the Requests library.
Yahoo Finance
Yahoo Finance (finance.yahoo.com) is a media property that provides financial news and data about stock quotes, financial reports, financial summaries, etc. A ticker symbol or stock symbol is used to search for the stock information of a particular company. A stock symbol may consist of letters, numbers, or a combination of both.
Import the packages
The lines of code below import the packages you installed in the previous section.
Use Requests to send an HTTP request
The Requests library is used to make HTTP requests using Python. We use the GET method or verb as we need to fetch the stock data from Yahoo Finance. We call the HTTP GET method on the requests module passing it the URL of the webpage we want to scrape data.
Parse the content using Beautiful Soup
The Beautiful Soup library is used to scrape websites to retrieve data from HTML and XML files. Beautiful Soup creates a parse tree from the given page that makes it easy to search and extract data.
Inspect the page to find the data
To find the stock price we need from the webpage, we need to inspect the webpage. To inspect the HTML page, we need to open the developer tools. There are several ways of opening the developer tools:
How to get Stock Market Data in Python?
One of the first sources from which you can get historical daily price-volume stock market data is Yahoo finance. You can use pandas_datareader or yfinance module to get the data and then can download or store in a csv file by using pandas.to_csv method.
How to get Stock Market Data for different geographies?
To get stock market data for different geographies, search the ticker symbol on Yahoo finance and use that as the ticker
S&P 500 Stock Tickers
If you want to analyse the stock market data for all the stocks which make up S&P 500 then below code will help you. It gets the list of stocks from the wikipedia page and then fetches the stock market data from yahoo finance.
Intraday or Minute Frequency Stock Data
yfinance module can be used to fetch the minute level stock market data. It returns the stock market data for the last 7 days.
Resample Stock Data
During strategy modelling, you might be required to work with a custom frequency of stock market data such as 15 minutes or 1 hour or even 1 month.
Fundamental Data
We have used yfinance to get the fundamental data. The first step is to set the ticker and then call the appropriate properties to get the right stock market data.
Futures and Options Data
If you are looking to get Options chain data then you can refer to the FREE course on Getting Market Data on Quantra.
2. Loading and Preparation of Data
For the project we will be using the all_stocks_5yrs csv file which includes stock data for 5 years and has seven columns which are listed below.
3. Understanding the Data
From the whole dataset, we will first extract all the unique stock ticks name with the help of unique function. In the dataset, we have 444 different stock names.
4. Creating a new Dataframe and Training data
To make our study easier we will only consider the closing market price and predict the closing market price using Python. The whole train data preparation is shown in the steps below. Comments are added for your reference.
5. Building LSTM Model
The LSTM model will have two LSTM layers with 50 neurons and two Dense layers, one with 25 neurons and the other with one neuron.
6. Compiling the Model
The LSTM model is compiled using the mean squared error (MSE) loss function and the adam optimizer.
7. Testing the model on testing data
The code below will get all the rows above the training_data_len from the column of the closing price. Then convert the x_test data set into the NumPy arrays so that they can be used to train the LSTM model.
8. Error Calculation
RMSE is the root mean squared error, which helps to measure the accuracy of the model.
Visualize Real-Time Stock Price with Python
I will start this task by importing all the necessary package that we need to get an visualize the real-time stock prices with Python. Now let’s import all the necessary libraries to get started with the task:
Real-Time Stock Price

A comprehensive guide to downloading stock prices in Python
The goal of this short article is to show how easy it is to download stock prices (and stock-related data) in Python. In this article I present two approaches, both using Yahoo Finance as the data source.
Downloading the stock prices using yfinance
yfinance is a very convenient library, which is my go-to library for downloading stock prices. It was previously known as fix_yahoo_finance. The short history of the library is that is started as a fix to the popular pandas_datareader library. With time, Yahoo Finance changed the API and the connected functionalities were deprecated.
Downloading the stock prices using yahoofinancials
The second library I wanted to mention in this article is yahoofinancials. While I find it a bit more demanding to work with this library, it provides a lot of information that is not available in yfinance. Let’s start with downloading Tesla’s historical stock prices:
Conclusions
In this article, I showed how to easily download historical stock prices from Yahoo Finance. I started with a one-liner using the yfinance library and then gradually dived deeper into extracting more information on the stock (and the company). Using the mentioned libraries, we can download pretty much all the information available at Yahoo Finance.
How I learned to analyze stock prices using Python
A beginners guide to comparing Amazon, Apple, Microsoft and Tesla stock for Investment.
Stock Open Prices
I use the following Python libraries below to import the data and perform the data visualization for analysis. My source code and workbook are hosted on Jovian.
Stock Volume
The Graph above shows the volume traded of all four companies relative to each other over the last five years. In this case, APPL is clearly the most traded by volume, with TSLA and MSFT following. Despite the higher opening prices, it can be seen that AMZN is the lowest traded by volume.
Market Capitalization
Using the volume or stock prices do not always provide a good comparison between companies. Market Capitalization is the total value of a publicly traded company’s shares and can be used to evaluate how much a company is worth.
Moving Averages
Stock prices tend to be highly volatile and prices change quickly with time. One technical analysis tool which is used to smooth out prices and observe the underlying trend is Moving Averages. To observe any trend or pattern a 50-day or 200-day average can be plotted using python.
Volatility
Volatility measures the rate of fluctuations in the stock prices over time. It can be determined by calculating the percentage increase in stock value compared to the previous day. The bigger the value either positive or negative the more volatile the stock is. It indicates the level of risk associated with the price changes of the stock.
Further steps
Besides the above metrics, Python can also be used to research other fundamental data such as Ratios (Price to Book, Price to Earnings), Revenues, Balances, and Cash Flows. These are all useful in analyzing a company’s performance and likely profitability for long term investment.
