Get Financial Data from Yahoo Finance with Python

In this article, we will see how to get financial data from Yahoo Finance using Python. We can retrieve company financial information (e.g. financial ratios), as well as historical market data by using this. 

Installation:

Let us install them via pip commands

pip install yfinance

Once it is installed, we can import yfinance package in python code We need to pass as an argument of Ticker i.e. the ticker of the company

Note: A stock symbol or a ticker is a unique series of letters assigned to a security for trading purposes. For example:

1. For Amazon, it is “AMZN”
2. For Facebook, it is “FB”
3. For Google, it is “GOOGL”

Below are various programs which depict how to retrieve Financial Data from Yahoo Finance: 

Let us take the results for Facebook and hence using “FB”.

Python3

import yfinance as yahooFinance

# Here We are getting Facebook financial information
# We need to pass FB as argument for that
GetFacebookInformation = yahooFinance.Ticker("FB")

# whole python dictionary is printed here
print(GetFacebookInformation.info)

Output :

We can retrieve financial key metrics like Company Sector, Price Earnings Ratio, and Company Beta from the above dictionary of items easily. Let us see the below code.

Python3

import yfinance as yahooFinance


GetFacebookInformation = yahooFinance.Ticker("FB")

# display Company Sector
print("Company Sector : ", GetFacebookInformation.info['sector'])

# display Price Earnings Ratio
print("Price Earnings Ratio : ", GetFacebookInformation.info['trailingPE'])

# display Company Beta
print(" Company Beta : ", GetFacebookInformation.info['beta'])

Output :

Company Sector :  Communication Services
Price Earnings Ratio :  31.029732
 Company Beta :  1.286265

Though we have retrieved few financial key metrics, as it is a dictionary value, we can split that by means of key-value pair. 

Python3

import yfinance as yahooFinance
GetFacebookInformation = yahooFinance.Ticker("FB")

# get all key value pairs that are available
for key, value in GetFacebookInformation.info.items():
    print(key, ":", value)

Output :

We can retrieve historical market prices too and display them.

Python3

import yfinance as yahooFinance


GetFacebookInformation = yahooFinance.Ticker("FB")

# Let us  get historical stock prices for Facebook
# covering the past few years.
# max->maximum number of daily prices available
# for Facebook.
# Valid options are 1d, 5d, 1mo, 3mo, 6mo, 1y, 2y,
# 5y, 10y and ytd.
print(GetFacebookInformation.history(period="max"))

Output :

Even we can have the data for 1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, and ytd. 

Let us check out for 6 months

Python3

import yfinance as yahooFinance


GetFacebookInformation = yahooFinance.Ticker("FB")

# Valid options are 1d, 5d, 1mo, 3mo, 6mo, 1y,
# 2y, 5y, 10y and ytd.
print(GetFacebookInformation.history(period="6mo"))

Output :

We have the flexibility to get historical market data for the provided start and end dates too.

Python3

import yfinance as yahooFinance

# in order to specify start date and
# end date we need datetime package
import datetime

# startDate , as per our convenience we can modify
startDate = datetime.datetime(2019, 5, 31)

# endDate , as per our convenience we can modify
endDate = datetime.datetime(2021, 1, 30)
GetFacebookInformation = yahooFinance.Ticker("FB")

# pass the parameters as the taken dates for start and end
print(GetFacebookInformation.history(start=startDate,
                                     end=endDate))

Output :
