getting Market cap data using Yfinance

I was trying to get market cap data of stocks using yfinance. Here is my code:

import yfinance as yf
import numpy as np
from pandas_datareader import data
import pandas as pd
import pandas_datareader as web

tickers=pd.read_excel('C:/Users/Administrator/Desktop/bse.xlsx')
UndervaluedCompanies=[]

market_cap_data = web.get_quote_yahoo(tickers)['marketCap']

# Get the P/E ratio directly
pe_data = web.get_quote_yahoo(tickers)['trailingPE']

# print stock and p/e ratio
for stock, pe in zip(tickers, pe_data):
print(stock, pe)

By using this code I get the following error:

*** IndexError: list index out of range

I attach screenshots of the error and also of the DataFrame

I referred to the url as specified below as to circumvent this issue.

Yfinance IndexError: list index out of range

The modified code made using the fix given in the above url is:

import yfinance as yf
import pandas as pd
import pandas_datareader as web
import pandas_datareader as pdr

from pandas_datareader import data

data =pd.read_excel('C:/Users/Administrator/Desktop/bse.xlsx')
ticker = data['Ticker']
rows = []

for ticker in ticker:

  try:
    market_data =  data.get_quote_yahoo(ticker)['marketCap']
  except IndexError as e:
    print(f'{ticker}: {e}')  # print the ticker and the error
    print('n')

By using the above code I am getting an error as described in the screenshot:

By using the code I am getting the following error:

KeyError: ‘regularMarketPrice

The screenshot of the same is as shown:

On clicking on the file which is mentioned in error we can see that the error is caused by the function def_read_lines. The screenshot is attached below:

I did try using the yahooquery library but in the values dataframe all the values are populated as error values and not the actual market cap values as shown:

I am not understanding where am I going wrong. Any help will be appreciated

Answer

It could be that some of the ticker in your excel file aren’t listed or there is some kind of naming issue. So i solved using try to download the stocks one by one with data.get_qoute_yahoo('ticker') and then with pd.concat() I obtained my dataframe.

import yfinance as yf
from pandas_datareader import data
        
tickers=pd.read_excel('C:/Users/Administrator/Desktop/bse.xlsx')
    
market_data=[]
  for ticker in tickers:
      print(ticker)
           try: 
               market_data.append(web.get_quote_yahoo(ticker)['marketCap'])
           except:
               print('Error with: ', ticker)
df=pd.concat(market_data, axis=0)
display(df)
