title: Downloading mutliple stocks at once from yahoo finance python
body: <p>I have a question about the function of yahoo finance using the pandas data reader. I'm using for months now a list with stock tickers and execute it in the following lines:</p>
  
  <pre><code>import pandas_datareader as pdr
  import datetime
  
  stocks = ["stock1","stock2",....]
  start = datetime.datetime(2012,5,31)
  end = datetime.datetime(2018,3,1)
  
  f = pdr.DataReader(stocks, 'yahoo',start,end)
  </code></pre>
  
  <p>Since yesterday i get the error "IndexError: list index out of range", which appears only if I try to get multiple stocks.</p>
  
  <p>Has anything changed in recent days which I have to consider or do you have a better solution for my problem?</p>
