Scrape Yahoo Finance with Python and BeautifulSoup: All You Need to Know

Data Yahoo Finance: Why It Is So Valuable?

Financial data has always been among the most valuable resources in the market. If you make a proper analysis, you will have a significantly better chance chance to solve your organization’s financial issues and grow your business. Today, Yahoo Finance is one of the most popular financial web sources with free access. Through this article, we will build a web crawler to scrape Yahoo Finance real-time stock data and other most active Yahoo Finance data like world indices, currencies, and cryptocurrencies.

Let’s reveal what Yahoo Finance is, why to scrape financial data, and how to download data from Yahoo Finance with Python.

What is Yahoo Finance?

Yahoo Finance provides various financial data like currency trends, financial reports, finance stock quotes, general news from the financial market, etc. Whether you are a business owner or investor, you will always get interesting and valuable insights from the Yahoo Finance page or Yahoo Finance app.

Note: Yahoo Finance discontinued its official API in 2017. All scraping methods described in this article interact with Yahoo Finance’s public web pages directly. Keep in mind that Yahoo’s page structure may change over time, which can require updates to the code. Always review Yahoo Finance’s Terms of Service before scraping at scale.

Reasons For Scraping Yahoo Finance

If you are working in finance or just interested in trading and investments, scraping Yahoo Finance page is a must. Financial data collected in real-time will enable you to have a wealth of information to make an up-to-date investment or financial analysis.

Scraping data from Yahoo Finance is especially needed for stock trading organizations that can download historical stock data from Yahoo Finance into Excel and make stock market predictions based on the fetched information.

To sum up the above, we can state that by scraping financial data you can make:

• Sentiment analysis of the market

• Financial market research

• Stock market prediction

Web Scraping Yahoo Finance Python Solution

Before building a crawler, you need to import the following libraries: Pandas and BeautifulSoup. Pandas library is used to arrange the extracted data as tables, while the Beautiful Soup handles HTML parsing in Python. Additional requirement is Requests library to send HTTP requests to Yahoo Finance.

Install all required libraries with a single command:

pip install requests beautifulsoup4 pandas

Then import them at the top of your script:

import requests
from bs4 import BeautifulSoup
import pandas as pd

A note on request headers: Yahoo Finance may block requests that do not look like they come from a real browser. Always include a User-Agent header to avoid getting blocked:

headers = {
“User-Agent”: “Mozilla/5.0 (Windows NT 10.0; Win64; x64) “
“AppleWebKit/537.36 (KHTML, like Gecko) “
“Chrome/120.0.0.0 Safari/537.36”
}

Dynamic content: Yahoo Finance renders a significant part of its data with JavaScript after the loading of the initial page. BeautifulSoup only parses static HTML so if a value seems to be missing in your results, it is likely loaded dynamically. In those cases you will need a browser automation tool like Selenium to fully render the page before parsing.

Cryptocurrencies

A digital currency known as cryptocurrency is a localized system founded on blockchain tech with advanced protection. It is a global phenomenon with considerable growth in recent years, attracting many investors.

The code below scrapes the cryptocurrency listings from Yahoo Finance’s dedicated crypto page. It targets table rows in the HTML and extracts name, price, change, and percent change for each entry.

import requests
from bs4 import BeautifulSoup
import pandas as pd

headers = {
“User-Agent”: “Mozilla/5.0 (Windows NT 10.0; Win64; x64) “
“AppleWebKit/537.36 (KHTML, like Gecko) “
“Chrome/120.0.0.0 Safari/537.36”
}

url = “https://finance.yahoo.com/crypto/”
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, “html.parser”)

names, prices, changes, percent_changes = [], [], [], []

for row in soup.select(“tbody tr”):
cols = row.find_all(“td”)
if len(cols) >= 5:
names.append(cols[1].get_text(strip=True))
prices.append(cols[2].get_text(strip=True))
changes.append(cols[3].get_text(strip=True))
percent_changes.append(cols[4].get_text(strip=True))

df = pd.DataFrame({
“Name”: names,
“Price”: prices,
“Change”: changes,
“% Change”: percent_changes
})
print(df)

Currencies

The approach to scraping the currency data is the same as in the above case. Yahoo Finance lists currency pairs on a dedicated page. The code below extracts currency pair names, prices, and change values by targeting the data table rows:

import requests
from bs4 import BeautifulSoup
import pandas as pd

headers = {
“User-Agent”: “Mozilla/5.0 (Windows NT 10.0; Win64; x64) “
“AppleWebKit/537.36 (KHTML, like Gecko) “
“Chrome/120.0.0.0 Safari/537.36”
}

url = “https://finance.yahoo.com/markets/currencies/”
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, “html.parser”)

names, prices, changes, percent_changes = [], [], [], []

for row in soup.select(“tbody tr”):
cols = row.find_all(“td”)
if len(cols) >= 5:
names.append(cols[0].get_text(strip=True))
prices.append(cols[1].get_text(strip=True))
changes.append(cols[2].get_text(strip=True))
percent_changes.append(cols[3].get_text(strip=True))

df = pd.DataFrame({
“Name”: names,
“Price”: prices,
“Change”: changes,
“% Change”: percent_changes
})
print(df)

World Indices

MSCI World is a market cap-weighted index of 1,649 stocks. The index and its dynamics show the attitude of investing in companies of any size and field.

The code below will enable scraping world indices’ data like prices, changes in percentage, and market volume.

import requests
from bs4 import BeautifulSoup
import pandas as pd

headers = {
“User-Agent”: “Mozilla/5.0 (Windows NT 10.0; Win64; x64) “
“AppleWebKit/537.36 (KHTML, like Gecko) “
“Chrome/120.0.0.0 Safari/537.36”
}

url = “https://finance.yahoo.com/markets/world-indices/”
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, “html.parser”)

names, prices, changes, percent_changes = [], [], [], []

for row in soup.select(“tbody tr”):
cols = row.find_all(“td”)
if len(cols) >= 5:
names.append(cols[0].get_text(strip=True))
prices.append(cols[1].get_text(strip=True))
changes.append(cols[2].get_text(strip=True))
percent_changes.append(cols[3].get_text(strip=True))

df = pd.DataFrame({
“Name”: names,
“Price”: prices,
“Change”: changes,
“% Change”: percent_changes
})
print(df)

Most Active Stocks

The shares on the exchange with the highest volume for a certain period are the most active. Because of the value of the latest information affecting the entry of stocks into the market, stock trading volumes grow above average, which induces investors to sell or buy shares at high returns.

The code for scraping most active stocks with such details as symbol, name, price, change, percent change, market cap, and average volume, is coming below.

import requests
from bs4 import BeautifulSoup
import pandas as pd

headers = {
“User-Agent”: “Mozilla/5.0 (Windows NT 10.0; Win64; x64) “
“AppleWebKit/537.36 (KHTML, like Gecko) “
“Chrome/120.0.0.0 Safari/537.36”
}

url = “https://finance.yahoo.com/markets/stocks/most-active/”
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, “html.parser”)

symbols, names, prices, changes, percent_changes, market_caps, avg_volumes = \
[], [], [], [], [], [], []

for row in soup.select(“tbody tr”):
cols = row.find_all(“td”)
if len(cols) >= 7:
symbols.append(cols[0].get_text(strip=True))
names.append(cols[1].get_text(strip=True))
prices.append(cols[2].get_text(strip=True))
changes.append(cols[3].get_text(strip=True))
percent_changes.append(cols[4].get_text(strip=True))
market_caps.append(cols[5].get_text(strip=True))
avg_volumes.append(cols[6].get_text(strip=True))

df = pd.DataFrame({
“Symbol”: symbols,
“Name”: names,
“Price”: prices,
“Change”: changes,
“% Change”: percent_changes,
“Market Cap”: market_caps,
“Avg Volume”: avg_volumes
})
print(df)

Scraping Individual Stock Quotes

Yahoo Finance uses a custom <fin-streamer> HTML tag to display live price data on individual stock quote pages. The example below shows how to extract the current price, change, and percent change for any ticker:

import requests
from bs4 import BeautifulSoup

headers = {
“User-Agent”: “Mozilla/5.0 (Windows NT 10.0; Win64; x64) “
“AppleWebKit/537.36 (KHTML, like Gecko) “
“Chrome/120.0.0.0 Safari/537.36”
}

ticker = “AAPL”
url = f”https://finance.yahoo.com/quote/{ticker}”
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.text, “html.parser”)

price = soup.find(“fin-streamer”, {“data-field”: “regularMarketPrice”})
change = soup.find(“fin-streamer”, {“data-field”: “regularMarketChange”})
pct_change = soup.find(“fin-streamer”, {“data-field”: “regularMarketChangePercent”})

print(f”Ticker: {ticker}”)
print(f”Price: {price.text if price else ‘N/A’}”)
print(f”Change: {change.text if change else ‘N/A’}”)
print(f”% Change: {pct_change.text if pct_change else ‘N/A’}”)

If necessary, this approach can be looped over a list of tickers to collect quote data across multiple companies.
