[Borda]

addresses issue when data are not found in requested page, to reproduce:

import pandas_datareader.data as web

# Fetch stock data using pandas_datareader
def fetch_stock_data(symbol='AAPL', start_date='2020-01-01', end_date='2021-01-01'):
    df = web.DataReader(symbol, 'yahoo', start_date, end_date)
    return df['Close'].values

print(fetch_stock_data())
